Do We Really Need Fiber To The Home (FTTH) in India?

Do We Really Need Fiber To The Home (FTTH) in IndiaCarrying on with my previous post about broadband connectivity in India, I will be talking about FTTH i.e Fiber to the home. What is FTTH, brief introduction to technology behind it, and scene of FTTH in India.

To get idea of fiber to home, we first need to understand basic difference between communication over conventional copper, wireless mediums and next of fiber.

The biggest problem in using copper in communication is “noise”. Copper pairs get noisy over distance, apart from getting too much effect of interference from nearby environment.

Now to carry more bandwidth, one needs to use really high frequencies (like we do in various flavors of DSL), and high frequencies are effected by noise even more. Imagine noise as road block interrupting traffic, and high frequency as car running at high speed!

Till now there has been no way out to the noise problem of copper. A lot of research work is still going on, but till now all we see is multiple bonding of pairs for increasing speeds i.e what At&t seems doing in US.

Next, if you look at wireless communication – as I explained in my last post due to limited spectrum, overall capacity is very much limited and one can’t provide high speed broadband for very low rates to everyone. That is what makes 3G, EVDO and other stuff expensive.

Now coming on main part of this post – fiber. In case of fiber, communication is done using light which travels in whole fiber via a simple Physics rule called total internal reflection. Principle is quite simple, but it makes communication very effective as fiber is NOT prone to interference by any external element like other wires, apart from that loss of signal per Km is way too less in fiber as compared to copper. This makes fiber a very good “Physical” medium for carrying high bandwidth.

Considering those simple physical properties, it seems like fiber is really awesome, and should be used everywhere. Well there are few other important things when we discuss copper Vs fiber like it’s very hard to splice fiber, one needs a dedicated team of trained technicians to splice fiber, apart from that if a fiber gets damaged, it’s again hard to fix it as compared to just rejoining copper.

Apart from that a fiber splicing kit costs as high as $1000 as compared to less then $1 cutter used in copper. Also, till now all computers still talk in electrical signals, and whatever way we go at the end, we need to have electrical signals, thus we need to convert light impulses in fiber back to electrical impulses using ONT – Optical Network Termination. All these factors make fiber quite expensive. ONT still cost as high as $500 which is way too high amount considering average user pays less then 1/5th of that in a year.

Do we really need FTTH in India?

Well, that’s a hard question. Answer varies.

One thing we always talk about is Internet speed or bandwidth. Fiber has very high bandwidth, and there is no other alternate. It’s true, but question is – do we really need to deliver that much high bandwidth to all end users?

Using an advance DWDM equipment, one can carry as high as 10Gbps over single wavelength in a fiber. There are 160 possible wavelength, and thus in theory, one can give as high as 1.6Tbps over single fiber pair. (In real that is quite less due to limitation from switches, protocol running on top etc).

Yesterday we share a post on MTNL’s FTTH offering on TelecomTalk. Well they just rolled FTTH out and are “capable” of giving 1Gbps speed to end user, but if you notice plan 1Mbps still costs 999Rs a month. You can imagine cost of 1000 times more bandwidth!

Firstly I would like to say 100Mbps, 1Gbps sounds very “awesome” speed, but fact is in real people HARDLY need that much speed and we can’t ignore that fact specially when we are demanding for really expensive technologies.

Few days back, I had a discussion with my friend living in Sweden. He just got a upgrade from 16Mbps DSL to 100Mbps fiber. I asked him for his feedback over performance, and his reply was “Anurag, other then good upload speed, I hardly see any difference”

So why he missed to see a 6 times more faster connection?

Well, at 16Mbps, one can download 2MB every second. If you look at average web-page size, you will see average page on modern sites are well below 500KB, thus he can get whole page in 250ms. An average Youtube video is around 20-25MB, and can get that in 10-12seconds on DSL. Even for heavy downloading work (although he doesn’t really do that), he can get a 1GB file in 500seconds (even less then 10mins).

Now people hardly do anything “new” or “fast” in real world on speeds beyond 10-15Mbps. Unless you plan to share that bandwidth up on multiple computers. Again, I am talking about bandwidth requirement on average computer.

But yes, there’s a big problem in DSL – very slow upload speed. It is due to fact that co-axial wires are tightly packed in big copper trunks as they get out from exchange and they are spliced further so on as they reach end user. So when a end user sends some data to central exchange (upload…) the weak signal (because of low power consumption by CPE) goes on, and as it gets more closer to exchange, it becomes even more weak, apart from fact that it gets into tightly bundled 100pair trunks which are carrying data for lot of other users.

This causes “cross-talk” and even reduces signal strength degrading upload speeds. He had 16Mbps download while 500Kbps upload DSL connection, while now he has 100Mbps (up & down symmetrical) and one can surely tell difference in 500Kbps Vs 100Mbps upload speed.

Coming back on point – if one needs 5-10Mbps, we can easily get it on existing DSL connections, and we don’t really need FTTH. Problem comes when more and more subscribe to 10Mbps plan, and it increases cross talk further degrading speed. But such cases are possible when a whole colony/street/apartment is demanding for high speed broadband and remember in all such cases it is economically feasible to bring fiber close to that street and from there back on copper.

This is known as FTTB/C – Fiber to the Building/ Fiber to the Cabinet. From that cabinet, one can carry signal over copper via VDSL or even conventional cat5 ethernet. Such hybrid fiber-copper models are really good in bringing down cost of expensive FTTH technology + they have enough bandwidth to serve demand. Don’t say you can’t get 10Gbps on VDSL (point is – how many people really need it!) :P

Well that’s all about basic of FTTH. More to come soon! ;)

    Does FTTH work better than DSL in peak hours because I cuurently have 16 Mbps plan from YOU Broadband, which dies in peak hours. But my local cable guy is FTTH at 6 Mbps for 350 GB at Rs 6000 fir a year. So does FTTH provide more reliable service than DSL?

    Hi Anurag,
    Does the technology has any side effects on health?

  • uday July 10, 2013 3:13 pm

    @anurag,
    BSNL is providing FTTH with 16Mbps plan for 6999/-
    On the other hand Tata Docomo is providing Internet Leased Line (ILL) of 1Mbps for nearly the same amount. Tata is also providing the Fiber connection.
    What do you think, which one is better for our business. (we need around 100GB of Downloads and 100GB of upload per month)
    Please Do reply.

    • Anurag Bhatia July 11, 2013 12:54 am

      Hi Uday

      I strongly guess BSNL’s FTTH offering is home/business grade connection with contention ratio Vs Tata’s offering which is a leased line (usually with 1:1 contention).

      No doubt speed difference is way too much to consider Tata. You should checkout with other users of BSNL FTTH to get idea of quality of last mile and uptime and if that’s OK and if you are not concerned too much about bit high latency due to their weird routing then BSNL will be a good choice. For under 100GB you will very likely get way beyond 1Mbps (what Tata is offering). But if you need ultra low latency with 1:1 contention then please check with BSNL first on what quality/SLA is there on these FTTH connections. Unfortunately I didn’t saw any contention defination on their page – bsnl.in/opencms/bsnl/BSNL/services/broadband/bb_ftth.html

      On their home broadband it used to be 1:30 which was later reduced to 1:20. Not sure what’s on FTTH.

      Good luck!

  • Samuel June 25, 2013 3:49 pm

    Well the whole point of getting 100 megabytes per sec connection, is to prove that there is an ever growing market. This topic would have been quite relevant (to Indians), had it been posted 5-6 years ago. I used little of Youtube, more into emails and facebook.. and was quite content with that. In fact, I thought that the Internet had already reached the peak of evolution.

    Well FTTH pays well in these circumstances (future plot)
    1) Consider, Video phone conversations happening in real time
    2) All services these days are cloud based. Take Games on the Cloud for example, which would need to run at ULTRA LOW latencies, for it to be classified Entertaining.
    3) Monitor sizes are getting bigger, better and going beyond HD. Imagine, what resolutions you would be watching 4-5 years from now. (I was very much content with 720p for a long time)….
    ……. and so on.

    I’d strongly recommend, you print this article, and read what you wrote sometime after 2018. If you were practicing blogging skills, well you should have picked a more simpler topic – such as How hard is criticism as a full time practice?

    • Anurag Bhatia July 11, 2013 12:47 am

      Dear Samuel

      What you are saying is right from one of dimensions which is “innovation”. I love innovation just like everyone else but I am against what BSNL is doing on name of innovation and that too on public money.

      So e.g bringing 100Mbps or 1Gbps is a good idea, no doubt. But bringing 8Mbps on fiber while capping copper on 512Kbps or usual 2-4Mbps plans is stupid. And all this stupidity is on tax payer’s money. If Airtel, Tata or any other private player does that it wouldn’t be a big concern.

      This eventually pulls us down to classic economical debate on whether or not Govt. should run companies in form of PSU’s or simply make a good level ground for private players to do it.

  • rahul June 7, 2013 5:17 pm

    Nicely explained but the issue is that I need FTTH to move on from 2MBPS to 4 MBPS. 2 MBPS is the maximum speed I will get on a copper network

    • Rohit June 7, 2013 10:35 pm

      Rahul, it doesnot required FTTH to provide 4 MBPS of Bandwidth in broadband, I am working in ISP at Hyderabad. We provide 20 MBPS over FTTB.

  • benson May 24, 2013 5:22 pm

    hi friends! i here to warn you if your thinking of buying an internet connection and you have spectranet isp in your area dont ever buy it instead buy mtnl
    because their service is soo lame and the guys who repair the net are soo unprofessional they dont even now what “ping” means in online gaming
    and half time their internet is on “unindentified network” so beware choose reputed brands :)

  • neelkamal January 21, 2013 7:06 pm

    hi anurag,
    thanks for giving interesting detail about FTTH,
    i have taken broadband connection with speed 4 Mbps (DSL based) from BSNL but never get speed promised under the plan, which some times irritates me, now point is, why i should not go for FTTH connection? at least i will get the speed, the ISP promises…..
    vily1309

    • Anurag Bhatia March 20, 2013 1:48 am

      Likely you will still not get that much speed. Again that will be wild guess but mostly last mile on DSL isn’t that big issue on BSNL unless you are really very far (say 3-4km ) away from exchange. Before that on ADSL2+ they can easily get you 4Mbps.

      So you get my point that bottleneck is not last mile, likely it’s internal network’s capacity, capacity on transit links + high latency with outside servers which cause issue on TCP window size. So on 100Mbps fiber connection with 100Mbps downstream connection (tested from ISP’s local PoP), you will NEVER get 100Mbps with outside servers due to high latency cause reduction. Read more on TCP window size concept and you will get idea.

  • Jogi Ram August 28, 2012 10:33 pm

    Dear Anurag,
    You have really covered the things in brief and to the point but do u kw the need for individuals will be gradually increasing for higher bandwidth to have fun on hdtv, 3d tv, interactive game, videoo conferencing, virtual class rooms, tele-medicine, house surveilance and many more applications, then copper is not the solution. No doubt we dont need fibre for all but technology and its availability is to be ensured just now to meet with future demand and that,s why Govgt of India has undertaken a plan for FTTH to link all village on fiber. Hoping u go through the latest developments which is called PON ( Passive Optical Network)

  • RV August 28, 2012 6:22 pm

    Dear Anurag,

    To start with I want to congratulate your young mind coming out with such a detailed and well written article.

    However, there are some gaps in your understanding and also some of the facts on FTTH that has evolved over the year that you need to look into.

    Nice article, And everything is said is true but we cant deny the fact the future of telecom industry is fiber, May be it is very very much costly today compared to DSL network. But time has come for ISP’s and Telecom operator to plan for Fiber based network..

    dsb_dsb :

    …..I have BSNL BB Home UL 750 connection which means that i have 2 mbps connection (512 Kbps speed) and ….

    Cannot understand your connection speed- 2 mbps connection (512 Kbps speed)

    Look at the news about technology on net many countries are planning to give their people free internet of same speed which i am paying for and yet have to suffer.

    Free internet!!! Where? which part of the world you are talking about.

    It’s a fundamental right like electricity & water why because it helps you keep up with the world & look at China & Japan they have better productivity because of greater connectivity.

    Fundamental right? Have a re-look at your civics books which you might have thrown many years ago. Electricity and Water are not fundamental rights. In many parts of India people have never seen what electricity is. And even in cities except some good ones people get electricity just for about 15 hours in a day (or even less). The condition of villages is even worse. They get electricity in either at day or at night (weekly rotation). And you are talking about free Internet, how they will run their PC (even if you provide them free of cost) without electricity.
    About your Internet connection: don’t opt for slow unlimited connection go for unlimited high speed with FUP plan like BSNL’s 900. 8 GB at high speed is sufficient and you get fair 256 kbps speed after that.

  • dsb_dsb January 15, 2012 3:19 pm

    Also understand one thing that poverty can not be eradicated by just helping them with basic necessities like food, clothes & house but by creating jobs and the better infrastructure will account for better opportunities & thus actually help in eradicating the poverty.

  • dsb_dsb January 15, 2012 3:11 pm

    I also thought that i should upgrade my plan but the budget seems to be a problem as there are no options in my city as i live in a city where internet is only provided by airtel (which i can’t opt for due to their FUP) & BSNL.

    I have BSNL BB Home UL 750 connection which means that i have 2 mbps connection (512 Kbps speed) and i also get disconnections quite regularly.

    Look at the news about technology on net many countries are planning to give their people free internet of same speed which i am paying for and yet have to suffer. It’s a fundamental right like electricity & water why because it helps you keep up with the world & look at China & Japan they have better productivity because of greater connectivity.

    Look at Singapore and other similar asian markets and the role that internet plays in their markets. It’s our this thinking that we can’t pay & have to invest large sums to upgrade which is keeping us behind all these nations.

    The people here in India will get better opportunities as faster internet connection means better reach. Take for e.g. a village with internet connection but without hospital or doctor here a video conferencing with doctor can help patients with preliminary treatment and can advice them properly for further treatment.
    Similarly primary education and bank facilities can be improved with higher speeds.

    We want to accept technologies but at an affordable pricing take for e.g. who will take FTTH connection at 3000/-rs. per month for 1 Mbps (BSNL FiBro 1) if they can provide the same speeds for under 1000/-rs. i will be enticed to upgrade to that plan & there will be more customers for them at that pricing than what they are offering now.

    Before upgradation to fibre one should do a survey of the market and i am sure there are many people who could use the services which FTTH can provide like one payment for many services like for television & internet & for data transmissions. I mean i know many people now who use internet regularly everyday to do everyday tasks and yet slow speeds is what is being offered in our country.

    See we Indians like a package why does BSNL charges every month the customers for their landline phone services they could introduce a yearly package for landline services with FTTH.

    See there are many ways the customers can be generated but for that we first need the will to make investments & secondly the vision to see the future as we want it.

  • dskushwaha January 15, 2012 9:01 am

    dsb_dsb :
    Well do we really need FTTH in India, yes we do.
    Why ?
    Because speed means power for e.g. I have a broadband unlimited connection from BSNL and say i want to listen to a music track which many websites offer for free online legally yet i have to pause or select a downgraded quality version just because of the lack of the speed.
    Secondly i want to stream videos via internet (Enough said).
    I am not a guy who just checks mail downloads some trials and does not use net for anything else, I comment, share stuff etc heck i even use internet for my studies. I download offline updates of many softwares as well as video and audio chat but all this at the expense of waiting for buffering……
    Well i would just like to say one thing that when broadband was first introduced it did not achieve high penetration but with time it grew bigger but not better and yes i like the fact that with fibers either thing works or don’t as this will help us subscribers to actually rectify the problem and not use temporary solutions. About the pricing well if someone will invest huge amounts he would like to earn as well but without higher penetration and better services at affordable costs it is not possible, thus although at first the rates won’t be very accessible but after sometime they will be for sure.

    You will not experience buffering with videos and low quality audios with a broadband connection offering actual speed of 2 mbps or above. You can exhaust your 10GB data plan in just 11 hours with this speedAnd with the present pricing of Internet connection we cannot expect much data at higher speeds.
    FTTH being a new technology requires huge investment and is not going to be cheap as compared to present worth using connections. And that too for a work which you can do with present technologies. So there is a need to upgrade your internet connection with presently available technologies than thinking about FTTH.
    Investing in new technologies like FTTH will be useful only if they have the capability to offer more data at much cheaper rates even with the speed comparable to present high speed data connections, because in present scenarios speed is not a constraint but data usage is.

    Considering the price of conventional ADSL broadband over twister copper lines, I’d bet that FTTH is going to be way too expensive for actual home users. Chances are, these lines would be leased by corporates, which is a boon for them as they’d be able to get much higher speeds/bandwidth than they are getting currently. With the advent of cloud computing I am sure a company with 10-20 systems might find traditional T1 leased lines choked.

  • Ram Mohan August 3, 2011 5:18 pm

    Anurag, coming from a student it is sad to hear. “Do We Really Need Fiber To The Home (FTTH) in India?” You sound like my college senior who thought 64 kbps leased line for my college in 1999 was too much bandwidth. He considered it way beyond what the students will ever need. I told him 64 kbps divided by just 20 students browsing simultaneously was enough to choke the leased line, to useless levels. Coming from a junior, naturally he did not appreciate my blunt comment and lack of enthusiasm. As I predicted the internet at college was dead on arrival with terrible speeds per user. Result we moved to text based browsing with the Lynx browser! I had a 33.3 kbps dial-up at home and with all that dedicated speed I was more than happy to use the real graphical internet from home.

    Moral of the story, in information technology never question the need for more of anything. You will become obsolete pretty soon.

    I was using Verizon FIOS for about 2.5 years in the US. Yes at 20 Mbps down and 5 Mbps up, it was too much bandwidth for causal web browsing. But the moment I started uploading my 5 MB+ JPEG from my DSLR to photo sharing sites I realized I could use more than the 5 Mbps upload speed. Same goes to uploading my 1080p HD videos on video sharing sites. Now I did not do this every single day. But on the days I did. I really, really appreciated the fact that I have the ability to do these tasks in a reasonable amount of time with FIOS.

    The fact is that nothing comes close to fiber for high upload speeds. And for that matter the download speeds are also poor in ADSL as many houses are beyond the one kilometer range from the telephone exchange. Copper lines from BSNL are poorly maintained at best. So you do get internet but at useless speeds. With fiber it’s either working or not working there is no in between.

    With the internet going crazy with video traffic it’s high time the entire world moves to fiber to home and not just India!

    Challenges are always there, fiber splicing, trained personnel, etc. But life will not be worth living without the challenges that simulate the human brain!

  • Anurag Bhatia May 4, 2011 2:41 am

    Dheeraj :
    @anurag
    Researchers in Japan have unveiled new optical connections that are capable of transferring more than 100 terabits of information per second through a single optical fibre. To try and put this in perspective, the data transfered per second through the connection is equivalent to three solid months of HD video or the contents of 250 double-sided Blu-ray discs.

    Dear Dheeraj,

    It is good that they are increasing speeds over fiber. Again, as said – technologies which are available today are already capable of offering very very high speed – something which we do not need at last mile as of now at cost of building expensive infrastructure. Most of such ultra high links are used on backbone where there is real demand of heavy bandwidth.

    If someone is laying totally new infrastructure, fiber is surely a very good choice, but for now wherever we have copper, that can go fine for meeting needs of atleast 2 more years. After that we might find even better copper technologies or may be ultra cheap fiber technologies.

    @shirish

    Dear Shirish, thanks for your comment.

    1.DSL based technologies have really advanced a lot. Commercial deployments now show real world speed of 40Mbps+
    The only limitation here remains the distance but FTTC/FTTB actually takes care of distance. If you go in theory, recently an Australian researcher was able to achieve real world speed of 100Mbps over existing DSL. His PhD. project indicates that some better cross talk canceling mechanism can increase speed a lot on existing hardware – same DSL modem, DSLAM etc. It will take sometime for his work t come in real life, but that all will be implemented by just firmware updates. Probably upgrade from ADSL2+ to next version (say ADSL3 or whatever) won’t require hardware upgrade.

    2.Thanks for money control article link. A nice one.
    Actually as Mr Bedi from Tulip telecom said – we already have plenty of International bandwidth, and technically it is not an issue. In real world problem is – companies like Tata, Reliance & Airtel who own lot of International asset do not have a good last mile (Airtel has in tier 1& 2 cities only). They don’t have any good way for pushing bandwidth on last mile, while BSNL who owns last mile in rest all places itself not really going good with that.

    You mentioned Sri Lanka cable. I highly doubt if Lanka cable from Tuticorin in Tamil Nadu still works! If you observe traceroute to Sri Lanka from BSNL’s network, you will find traffic going via Tata or Reliance, which is abnormal!

    Although for BSNL pricing will further come down because of their recent presence in EIG cable. Apart from that 3G & BWA will increase demand in International bandwidth – bringing over cost per use user/GB down.

    3.You are right about data coming from US. Over 80% data STILL comes from US and reason remains high cost of hosting in India. Cost of server hardware, datacenter, and reliable power makes hosting very expensive in India. Big players who have invested a ton in Infrastructure (submarine cables to US) and who have over 95% capacity lying free – want to extract maximum from that, rather then promoting datacenter/mirrors in India (which might bring cost down).

    Singapore, Korea, Japan – all have quite better infrastructure, and technologies available while India struggles for reliable power, followed by lack of good engineers which creates whole datacenter business challenging as compared to that of US.

    4.True. I didn’t made case of just FTTH, it was actually a part of post in followup of my last posts. Check http://telecomtalk.info/author/anurag

    Broadband policy is not really good one. Govt. is crazy about over charging for wired infrastructure, poor in giving req. amount of spectrum for wireless apart from poor in dealing with massive infrastructure BSNL is holding (which is lying useless and which can really bring revolution if utilized).

    5.Apps? Mmm…I wonder if any apps need more bandwidth then what is supported by “most of” ADSL, VDSL based connection (going on possible speeds and not the capped speeds). At 20Mbps you can have Phone+TV+broadband over same connection. Most of apps will be all fine beyond 8Mbps speeds (specially the media streaming apps).

    6.Good point!
    Yeah in most of FTTC/FTTB connection existing modems + existing last few meters copper will all go fine. This is one of great things which bring down cost and increases bandwidth. You might be having a BSNL pillar in your street which gets (100pair+) copper trunks from exchange. Now, if exchange is more then 2Km or so, BSNL can consider ditching out that heavy trunk and putting a fiber in. That cabinet can be upgraded with a DSLAM and next, (technically) all users will get high speed. No further need to put fiber to each home or changing end use CPE.

    Thanks for your comment. Appreciate your interest and questions.

  • Anurag Bhatia May 3, 2011 12:38 am

    Dear Selvam

    Firstly I would like to REPEAT again – PLEASE remember this is post on FTTH and NOT about phone infrastructure sharing. I would be happy if we choose some different platform for carrying on such discussion.

    Next, since you asked, let me clear it out:

    If BSNL does not shares it fibers (which have SURPLUS capacity) operators like Airtel, IDEA, Tata have no other way then to lay a parallel fiber. Even if you see most of India today – there are backbone rings of BSNL, Airtel, IDEA (in many areas), Tata (VSNL+TTSL), Vodafone etc.

    Now WHAT IS use of more and more parallel fibers? They increase redundancy, but beyond one point it is just wastage of money. Airtel, Tata put a lot of money to build separate infrastructure, and at the end they pass the cost to end user in terms of cost of service.

    Next, Please please and please stop calling ISP’s as thieves. It just shows low mentality. Comeon man everyone MAKES money. So if Airtel or Tata or Reliance are making money there’s nothing wrong in that. You can always point out if they do any illegal or unethical way but if they are running good business and making money – is that just the reason we should call them thieves?

    Whole Telecom/broadband/ISP thing needs a very high CAPEX and that comes usually from big players. E.g in case of Tata’s they put a ton of money in which key holder is Tata Sons. They have Steel industry, motor and many more things going on. If they put say 1000 crore in Steel, and they make a x amount out of it, then they want to make sure that they make same or more amount out of their communication business. If not, then what’s the point in spending few thousand crore in build up? Why not spend it somewhere else where they have good returns? Same applies for Reliance, Airtel, Vodafone etc. This is “business” man.

    BSNL has 4lakh employees? Not sure, last time I heard that number was somewhere close to 3lakh. But anyways, it is NOT making any good profit and it’s huge losses are something which worries Nation. Just saying that it holds 3lakh(+) employees job doesn’t means that it’s OK for them to waste Public money into useless technologies, inefficient network, and poor management.

    And you see because they didn’t shared infrastructure, that’s the reason Nation is still behind in broadband penetration. Just have a look at http://www.connectivityscorecard.org/countries/india

    Don’t you think that result is way too shameful for us? :(

    One query (feel free to add it to post)

    In FTTB/C scenarios, what happens to existing DSL modems/routers, are they useful or to be discarded. I am talking from a normal home user. Would the existing setup work or would he have to purchase new equipment (CPE). From what I have read the last yards or so would still be copper so it should be the same but more clarification welcomed.

  • shirish May 3, 2011 12:31 am

    Dear Anurag,
    I read the whole article and few obs. and queries :-

    1. From what I read about xDSL technologies in general most of them on copper cap out on 12 Mbps. For e.g. see the Google Chittagong experiment and the ad.

    2. While you are right for cost-effectiveness and general trend, I think you somehow forgot the most important of all issues, having own submarine links and having holistic competition. One of the more interesting article came around a year back. moneycontrol.com/news/business/pacnet-promises-lowered-internet-pricesindia_439165.html . Till BSNL and/or MTNL do not have their own lines or they do not invite more competitors in the upstream bandwidth wholesale bandwidth rates will not just come down. For my little mind, even if BSNL and MTNL would lay lines just upto Sri Lanka as Sri Lanka has lots of connectivity it would just make things cheaper for them as well as give them more power on the negotiating table when dealing with people like the TATA’s or Reliance’s for more links.

    3. The other part is also lots of data get routed to US because there are no Indian mirrors, from what little I know of Internet technologies, ISP’s have a fair idea as to which sites or services people use the most or atleast the technology exists to find out. Being able to have local mirrors and CDN’s would do so much more good as well. I read couple of years ago both Singapore and South Korea have tried that and have had some encouraging results.

    4. The broadband policy as a whole needs a major reworking. While you make the whole case of just technology, I think its more than that.

    5. What perhaps you are not focussing also are the apps. For e.g. if real broadband comes, then there would be lot more things people would use it for. Even on such low bandwidths I know of many of my friends who do torrenting, reading, writing webpages and chatting at the same time. Now if broadband was cheap(cheaper than today) then for sure, there would be places and apps for the same. For instance, you would see lot more action on Video Calls (dating,friends) and VOIP then you see today.

    It would need good policies, enabling environment and lot more entrepreneurs than the established ones to have competition.

    Thoughts for some future posts :)

    Dear Arjun,
    Mmm… your comments is all about telecom players (out of which most are not broadband players).
    A couple of things:
    1.BSNL 3G was big failure. They were sitting on 30,000 crore cash last year, now they are on 4000crore. They hardly have cash for just this current year. After that they NEED bail out package which will be given by Central Govt. from money of tax payers. That is the reason I dislike their policies to carry on lossy operation.
    2.BSNL gives broadband services in many areas where they are just ALONE (no other wired broadband compititor). I am writing this comment from a DSL connection in a village, and this is something good that they reach out non-profit markets like rural areas where no one else will be ready to come.
    But on the other hand, they are NOT ready to un-bundle last mile which is one of very bad policy. If today they agree to un-bundle last mile copper, tomorrow I will have option for going with BSNL, Airtel, Sify and few more players who will be interested in offering broadband using BSNL’s last mile and eventually paying some fixed fees.
    3.BSNL is yet not doing tower sharing, and other active infrastructure sharing. WHY so? Why not let others to use your infrastructure when over 90% of fiber are free, when over 80% of towers have free capacity?
    4.Govt. seemed failed to make BSNL to share infrastructure, and what next – they are coming up with a few billion $ National broadband plan. Unless that covers last mile fiber, that’s huge wastage of money. WHY to have more fibers running in parallel with BSNL (another Govt. owned company)? They should better make sure that whatever small % of area is left under BSNL, should be covered, and next they should start allowing private players to use surplus capacity BSNL is holding.
    Thanks.

    First thing BSNL loss because of politics only. see the telecom minister and his corruption.
    private party paying money to person who selected by tax payer to stop public sector company.
    how many towers constructed by private parties done as per rule?? still they using lot of microwave tower for giving media to BTS almost 80 percent of Private party tower run in microwave tower only. which very harmful to health and their transmission power to make big coverage they using high transmission power(not considering health rules) you are getting coverage and complaining company who is following health rules.
    just think in one factor 3g auction done all private party bid as per their requirement and for BSNL no option given and BSNL forced to pay all circle highest BId amount. is’t fare?

    ur article about Fiber connectivity need for india and i explain u about theft happen in copper wire what is ur solution for that? and security in copper wire is much less compare to fiber. fiber connectivity started in cities for giving connectivity to big corporate not to home. and tariff also not for normal people.

    plz explain ur expectation of money for upgrading to FTTH??? and one more thing as per current situation fiber price is 20 percent of copper price in bundle.

    BSNL spending money to give BB connectivity to even village. not like other operator. if BSNL thinks about profit na then no need of giving BB for villages. many remote areas private operator getting E1 connectivity from BSNL only for their BTS. other operator going on tower sharing many place because that tower is not their own. the get tower from contract person.

  • Anurag Bhatia May 2, 2011 6:09 pm

    Dear Arjun

    again it’s out of broadband stuff but anyways, see everyone has its own business model. E.g you will not hear lot about Tata Docomo in corporate world where demand is of very good coverage, while charges don’t really matter. Corporate people are OK in paying bit more, but need a good coverage. For them coverage and service quality matters lot rather then a cheap sms plan. They usually go with Airtel, Vodafone etc. While in Youth, you will find Tata Docomo quite popular due to cheap plans. Here demand is not of VERY high quality, but is of “something” affordable.

    Calling Airtel as best & Tata Docomo as worst is not correct. Both have different offering and are targetting different market segment. BSNL’s network is very much heterogeneous in terms of quality. At some places it’s very good, some places very bad. That’s actually a general property of Govt. work :)

    BSNL 3G was bit good initially, but later on with cheap unlimited plans – everything just messed up.

    Apart from that I heard from many friends that network was good until private players started offering 3G. So we all can guess well what happened….

    (also just a small advise – do NOT type in CAPS. It means you are screaming, which I guess you are not in this discussion. Also, it’s very painful for eyes to read stuff in CAPS).

    Thanks.

    BHATIA THANKS FOR THE INFO. FIRST OF ALL I UNDERSTOOD WHY OUR INDIANS PREFER BSNL 3G COZ IT’S HAVING COOL TARIFFS. BUT NOWADAYS THEY ARE VERY WORST IN QoS REALLY VERY BAD NETWORK QUALITY. BSNL SUCKS, WHILE COMING TO THE PART AIRTEL COVERAGE IS EXCELLENT IN ALL PARTS OF COUNTRY. IDEA AND VODAFONE ARE ALSO EXCELLENT IN NETWORK QUALITY AND COVERAGE LIKE AIRTEL. AIRCEL IS AVERAGE PLAYER IN INDIA, TATA DOCOMO AND UNINOR ARE WORST IN COVERAGE, I CAME TO KNOW WHY THESE PEOPLE ARE BECOME FOOLS TO CHOOSE BSNL 3G AND TATA DOCOMO AND UNINOR IN 2G.

  • Anurag Bhatia May 2, 2011 4:39 pm

    Ganesh :
    Also think about HD, 3D HD streaming. These services require about 40 MBps. 40 Megabytes i.e., 320Megabits line speed is required. I even shudder to think about Quad HD requirements!

    Thanks for comment Ganesh

    A couple of things:

    1.3D TV needs something close to 40Mbps (not MBps)

    2.Technology is very very new and there are very few commercial products available.
    It won’t be wrong to say that we will see 3D TV’s coming in commercially at “affordable rate” probably after 2years or so.

    3.We won’t really see 3D TV’s in small cities and villages where we have full copper on last mile. Probably they will come in metro areas, and most of people live their in apartments, small buildings which are already on FTTC (and followed by DSL), and if not, probably they will be upgraded (and even CAN BE upgraded) when demand will come. So for majority of potential 3D TV users, VDSL will be already there. VSDL can take speed up as high as 50Mbps, and probably by the time of real world deployment it will be even more better.

    So for now 3D TV doesn’t seems like a killer bandwidth application which surely need ONLY FTTH.

    Hope that clarifies.

    @Ganesh

    Dear Ganesh, thanks for your comment.

    SDSL, ADSL are all flavors of DSL. SDSL has 1:1, but remember deliverying SDSL is expensive as compared to ADSL. With lower allocated bandwidth and lower power consumption based CPE, it just goes fine.

    Before I go for cloud, coming on your last point – TV/Phone/Net = well that needs very very less bandwidth. A standard DVD quality stream takes just 2Mbps, while a full HD TV viewing needs 8Mbps. Phone needs just 50Kbps. Thus a connection with ATLEAST 8-10Mbps (whether on DSL or on FTTH or on cable) is all fine for Phone+net+TV.

    Coming on cloud point = well till now there is nothing like having full hard disk on cloud. Even so called “cloud OS” i.e Google cr48 netbook (I have one!!) also has a harddisk and it uses cloud for storing end user data which is mostly documents/spreadsheets/pictures etc and all that goes fine with 10-15Mbps. Till now there seems no serious/big offering to have FULL computing experience in cloud, running things 100% from cloud, and storing things 100% on cloud – need much more advanced technologies. Presently there is no such thing, and no one is yet sure when we will go 100% cloud (if we go ever!). So for now having FTTH deployment thinking it is must for cloud is not really good idea.

    Thanks.

  • Ganesh May 2, 2011 1:16 pm

    You see my friend, you have go it all wrong! Usually in DSL DL/UL ratio is 8:1. i.e., if DL is 8mbps, UL is 1mbps. If you want more UL speed, you can go for SDSL (symmetrical DSL) here UL=DL.
    And in DSL the UL speed is lower because of lower spectrum allocation.

    FTTH can be the much needed relief for soaring DSL/Cable costs. While we move towards cloud computing model, much of our data (atleast TB sized media) will be in the cloud and we would want to stream them to devices.

    Also there will never be a chance of unwanted/unused bandwidth! with FTTH we can have triple play (TV/Phone/Net). We can reduce the cost even more!

    The reason for lower Uploading speed is not the crosstalk, but the lower bandwidth alloted for Uploading than Downloading.

    With standard ADSL, the band from 26.000 kHz to 137.825 kHz is used for upstream communication, while 138 kHz – 1104 kHz is used for downstream communication.

    Anurag, By Viewing Your Comments I Understood That Most Of The Users of 3G Doesn’t Know How To Use It. Even They Don’t Know What Type of Airwave and Technology Used. Especially BSNL is The Useless Telecom Operator Always Sucks. These Idiotic People Never Accept Private Operators 3G Services. Especially TD(Tata Docomo) is The Worst Operator Who Was ReIntroduced 1Paisa/Second When Loop Mobile Discontinued This Tariff. No New Innovations From Tata Docomo, From This Idiotic Operator 3 Major Telecom Operators AirTel, Vodafone and Idea Lost Their Revenues. Leave Revenues, From This Idiotic Operator Aircel is One Of The Operator Who Is Struggling To Deploy Towers In The Country. So I Think There is No Need Of TATA DOCOMO,VIDEOCON,UNINOR, RELIANCE GSM AND ETISALAT DB In Telecom Industry.

    For home high speeds are needed if you want to watch High def TV as well through fiber like Verizon’s FIOS

    They have an “application” and “real need” and I agree they surely need FTTH.

    And regarding FiOS – whether it was a hit or not is still a question of debate in US. Verizon took a debt of $26 billion for that build, and they are NOT laying any more fiber for now. Till now they have covered hardly 30% of US. You see how expensive it seems in US. Telecom analysts, MBA guys can better predict if FiOS was a great deal to get hold on last mile fiber for Verizon OR something which takes company into debt.

    Good Luck Verizon!

    Hi

    3G has lot more to do then JUST plain broadband, please don’t ignore that fact. It has sort of dual advantage – in metro cities it offers very high capacity actually 2-3 times more then that of 2G. This capacity CAN be (and infact will be) used for voice users also. Thus, for metro cities where 2G spectrum is already chocked of load, 3G offers more high capacity for further expansion.

    Next, in Rural areas where DSL or any other wired connectivity just makes no sense, 3G is good way for “starting” of broadband services.

    Apart from that, private players gave 60,000crore+ in 3G spectrum to Govt = isn’t that a good gain for covering other fiscal losses? :)
    (don’t call 3G wasted tax payers money!)

    Anurag Bhatia :

    vishal :FTTH is advanced technology. I hope it will be installed as soon as possible. I have been looking for in my city since development has been started all over world and some cities. There are small numbers of companies available in developed cities in india. I want it with unlimited tariff. I have searched a lot about it and I found that the companies who launched fiber for residential users have restrict usage up to certain limit and then, rest of usage would have given at high cost otherwise speed cap (FUP). That makes unlimited tariff, a history.

    1.FTTH is advanced – yes it is. But just being advanced doesn’t makes it “good” enough for PSU like BSNL/MTNL to spend few thousand crore on it.
    2.Unlimited is all what you call it.
    Let me explain:
    E.g on BSNL 750Rs plan, you get unlimited usage at 512Kbps. If you pull data WHOLE month, ALL the time, you can get max – 165GB
    Now, when you can’t get data over 165GB, it just makes sense to call it unlimited.
    If you talk about a say 8Mbps connection (on DSL or fiber…) you can get 16 times more data which will be 2.6 TB in a month. Remember most of data comes from US (I would say in consumer segment visited websites, over 80% are still from US), and BSNL will be paying around 5-8Rs for every GB you transfer to it’s upstream provider – Tata Communications.
    So roughly taking rate for per GB as say 6Rs (just an estimate, only BSNL can calculate true cost of delivering per bit), 2.6TB will cost around 16000Rs to BSNL alone which they will be paying to upstream carrier. We need to add BSNL’s own network/backbone cost + cost of delivering bit on last mile. This will take cost even up, apart from adding BSNL’s own margin.
    So point is EVEN if you are ready to pay 16000Rs+ amount a month, you can’t get a “true” unlimited plan on 8Mbps. But yeah, you can always get plans with 200-300GB limit which is more then what you call as “unlimited” on present speed.
    So don’t be confused with offering – everything in true is limited

    Awesome Calculation and way of explanation..

    FTTH is mainly focus on Business people and corporate usage only. as u said normal user will watch youtube like websites only for them FTTH is not necessary but corporate surly need high speed network.

    BSNL is lunched FTTH in cities only not in village area for normal people and tariff also suited for Corporate only.This is the first step of evolution i say.

    Thus FTTH implemented in cities development work will be minimum so damage of Fiber
    is less.and surely its cost effective. and BSNL already maintaining Fiber’s everywhere for media [where other operator relay on microwave] and consider fact of theft of Copper wire. how many time did they replace theft copper wire? is that cost effective????

We need to add BSNL’s own network/backbone cost + cost of delivering bit on last mile. This will take cost even up, apart from adding BSNL’s own margin.

    So point is EVEN if you are ready to pay 16000Rs+ amount a month, you can’t get a “true” unlimited plan on 8Mbps. But yeah, you can always get plans with 200-300GB limit which is more then what you call as “unlimited” on present speed. :)

    So don’t be confused with offering – everything in true is limited :)

    True. BSNL just getting crazy with FTTH.

    See for new Operators/ISP – FTTH makes bit of sense (although not FTTH, but FTTB/C) but for BSNL who hold all copper pairs in country FTTH right now is MEANINGLESS. They may consider it after a couple of years or so. They can use existing copper in most of places to give 5-10Mbps connection. Remember, they are giving JUST 512kbps in unlimited usage plan. Their FTTH pricing seems even more crazy and that seems hardly for consumer segment, but for more for corporate segment, FTTH = Fiber to the Home for office :P

    @thangaraj

    Hi

    1.Copper is very expensive then fiber – half true. 10Km fiber Vs 10Km copper – fiber is surely cheap, but for small distances fiber is expensive.

    2.Splicing fiber, and fusion is still way too expensive which keeps cost of FTTH way too high as compared to DSL.

    3.DSLAM’s were MUST for getting broadband (dialup can’t do anymore) but FTTH isn’t a “must” for now given when we can increase speeds upto 20times more on existing copper.

    4.Distance limitation is there in copper – I already mentioned that. Simple fact is – FTTC, FTTB can keep distance of last copper loop way too less as compared to pure DSL implementation over copper. I am mean fiber is must, but taking it to each home seems pretty much useless. Instead one can stretch fiber more close to end user i.e to cabinet/building/street. This way is good as it can be easily upgraded to full FTTH when required after few years.

    I am not against fast broadband, but my point is – we should not build FTTH on tax payers money when more then 50% population has no idea what computer is!

    In case of Europe almost all FTTH builds are based on tax payers money.

    Nice article.

  • thangaraj May 1, 2011 12:24 pm

    @Anurag
    u missed one point about copper wire price. copper wire much more costlier then fiber and one more thing theft possibility also more in case of copper this is real time fact to change copper to fiber. like u said ONT’s are costly just like DSLAM’s in the beginning of BB introduction. so if they think price of DSLAM then still india in Dial up connectivity only. :P
    and one more point copper wire BB distance is limited more u further from exchange less speed u get due to loss. and cupper joint is easy but loss will increase every-time then ur speed also will reduce. in case of Fiber splicing lose is considerably less. after so many joint fiber can transmit full speed requirement. but in case of copper after few joints lose will be more. every time maintain copper is costly only.

    Really very useful info, Thanks to Anurag who always post innovative & important articles on telecom talk.

    Even BSNL also laying OFC for FTTH in his licensing circle & wasting money of Public. Whatever but this article clarify everything about our present needs. Thanks Anurag.

  • vishal May 1, 2011 1:15 am

    FTTH is advanced technology. I hope it will be installed as soon as possible. I have been looking for in my city since development has been started all over world and some cities. There are small numbers of companies available in developed cities in india. I want it with unlimited tariff. I have searched a lot about it and I found that the companies who launched fiber for residential users have restrict usage up to certain limit and then, rest of usage would have given at high cost otherwise speed cap (FUP). That makes unlimited tariff, a history.

    Nice article again, good work bro! But u know geeks can always find a way to use/maximize a 100 Mbps/ 1 Gbps Fiber connection.

    :)

    Actually it’s not just you but Google is also saying same thing. That is why they are deploying 1Gbps (in real world) in few rural areas of US. Giving off 1Gbps connection to end users and looking into possible trends. Well, it’s OK for players like Google to have such fun, but when we talk about Indian companies, and specially Govt. PSU’s – BSNL & MTNL it’s hard.

    My point here is – do you think it’s correct to build a network with taxpayers money which supports 1Gbps speed which seem to be of no use as of now? Remember 50% of India still struggles for basic food, shelter.

    I am not against new FTTH build ups, but we must understand advantages of fiber, and where it can be of real use. India’s 60-70% backbone runs over fiber (and rest on Microwave) which itself is very good since demand of bandwidth & distance of those connection is very big.

    I think Bharat already answered it + it’s all above Physical layer :)

    I am keeping focus on Physical layer in last 2 posts. What you run over Physical layer i.e on network layer & application is matter of your choice.

    And yes, Redhat is awesome for telecommunication too. Believe me – sooner or later all will converge and in unified communication, we will see more and more products like Asterisk PBX.

    Really g8 article, and wanna say that India need FTTB/C not FTTH.

    Yep. I wonder WHO really needs that!

    For new network build up – yes fiber makes sense but replacing existing infrastructure makes no sense at all. We are living in 500Kbps on copper when we go to 10Mbps on same system, while 50Mbps on VDSL with FTTC, then where exactly need comes for FTTH? It will probably make sense after few years.

    good question. I m also an CCNA student and also interested in Networking field and alsn want to do MCSE and RED HAT LINUX courses.

    @arjun… red hat enterprise linux server system is a best server os in world in telecommunication… they are many applications then microsoft windows server… virus free server… we can use for longer and large bandwindth network…
    @abhijit… u r doing ccna… k that rite.. its only to learn how to work network in server.. and their characterstics.. mcse is only for microsoft windows server only.. and red hat linux is also a server.. u r going learn how to processes the clints and blocks and their features…
