Reliance Jio Gets 10,000 Mobile Numbers to Run Voice Over LTE Trial

Department of Telecommunications (DoT) has provided 10,000 mobile numbers to Pan India 4G BWA spectrum winner Reliance Jio Infocom for trial of Voice over 4G LTE network, as requested by the company.

The number series allocated to Reliance Jio is 83378 for trial propose, and it will be used across Mumbai, Delhi and Jamnagar where Jio will soon start the trial run of VoLTE with 4000 mobile numbers each in Delhi and Mumbai and 2000 in Jamnagar (Gujarat).

It is not known that which technology Jio to use for voice over LTE-TD. As Jio does not have underlying 2G network, it may not be CSFB (circuit switch fall back), rather it would be VoIP using SPIRIT-DSP’s VVoIP engine.

According to our exclusive sources Reliance Jio will use Nokia Lumia 900 and some other smartphones for upcoming trial.

    Guys cool down, the testing doesn’t have to be done with Commertial Phone. These are trial. So they will use Test Phone (development in progress) with Test client (dev in progress) and finally when things becomes stable, they will make commetial devices, with stable software stacks. Its long way to go

    At last after all these years they are finally going to launch.
    But Lumia 900 does not support LTE on 2300MHz.

      Neither iphone too! :-(

      I cannot understand the reason, why they are launching on 2300MHz high frequency low wavelength band. India is the 7th largest country so it must also use lower frequencies like 700MHz (USA) and 800MHz (UK)

      And, in later days, telcos may face a lot of problem to provide International roaming on 4G. Ofcourse people don’t want to become bankrupt after using internet on IR. But still technology must be widely established like GSM and UMTS.

      So what’s your views on the same?

        Its really funny to see most phones like iPhone 5 and Lumia 920 support LTE on 700 / 800 / 850 / 900 / 1800 / 1700 / 2100 / 2600 and our Gov picked the only band that is not supported by any devices in the world for BWA. 2300MHz band is actually a total waste. No devices and no coverage.

            You can also think about the telecom minister back then who made all the stupid choices.

          Umm, who was the telecom minister in 2000 when BSNL was born. I know it was government of NDA(BJP alliance) but he did a good work in uniting scattered government cellular telephony.

          Current telecom minister was once educational minister. Spoiled CBSE 10th with CCE rule.

        “Govt to auction 700 MHz with swap option to 4G operators on 2300 MHz band” google it.

          Yes its a good option. But 700MHz auction will take place only after 1 year in 2014-2015. Also they are planing to price it Rs 47,508 for pan India. That is 4 times the amount paid by Reliance in 2010 for pan India.

          Dude, not so easily. The biggest telco lobby AVOID (Airtel, Vodafone, Idea) will definitely force operators not to participate in auction so as to reduce prices. So most probably, auction will postpone every time. I think BSNL will not purchase 700 MHz spectrum for now as it is in serious financial difficulties, same with Aircel and TD.

            Yes you are right Avoid may not participate and Aircel and Docomo are weak.

            But Reliance Jio is a direct competitor to AVOID. Relance will definitely participate.
            Also it is said that Ambani can directly influence many Gov decisions including voice for BWA players.

            Avoid will really feel the heat after Reliance Jio launch.

              United we stand divided we fall!

              AVOID are much more powerful than single standing Reliance. However, Reliance has support from government.

              Lets see what’s going to be next in the high profile drama :p

      Indian variant of Lumia 920 is set to support nine 4G bands, so don’t worry :)

      • Tharun George April 18, 2013 9:56 pm, 9:56 PM

        I checked Nokia India website and specification says LTE network bands: 1, 3, 8, 17, 4, 7, 20. Which are 2100, 1800, 1700, 2600, 900, 700, 800.

        Nokia may have Lumia 920 for 2300MHz LTE. But it might be only available through reliance Jio and may be as Locked.

          The simple solution to this problem is to use the Qualcomm RF360 chip in their mobiles, that is the one stop solution to all frequency band compatibility issues. It supports GSM, CDMA, HSPA, EVDO, LTE on any and every Frequency band ever heard of. If device manufacturers use this chip in their handsets we could have a truly global cell phone.

      If I remember correctly, then neither Lumia 900 nor the iPhone supports time duplexing.

    How can they use Lumia 900s when that’s not a 4G phone and when it doesn’t actually support the frequencies on which Reliance Jio is going to be operating? Sounds rather funny! :P

      The only phone available in India that supports TDD-LTE on 2300 MHz (i.e. band 40) is the Huawei Ascend P1 LTE And the only USB modem supporting the same is from Huawei too.
