Wireless Internet Why Speed Differs At Different Times In Different NetworksThe current major mobile internet deployment in India is EDGE with pockets of 3G deployed by couple of operators. EDGE gives a maximum speed of 384Kbps with per channel capacity being around 50Kbps max.

So a user on EDGE is atleast guaranteed a 64Kbps speed, which is fair enough for email and chat. EDGE is based on legacy GSM radio technology. On the other hand 3G has picked up the radio technology from CDMA. CDMA is superior in terms of data speeds when compared to GSM.

3G has WCDMA as radio technology for data access. Further upgrades to 3G are HSPA and HSPA+.With so many technologies users experience different speeds at different times in different networks.

The user experience depends on various factors and it is not a good idea to judge Bangalore network based on what is received in a Delhi network.

When a user is connected to the network he will be assigned one or more channels based on the network conditions. More the channels more is the speed. With HSPA networks the per channel data rate has increased tremendously. While in the nights if the network is free, users may experience speed upto 7 to 21 Mbps based on HSPA or HSPA+.

Important thing to note here is downlink and uplink speeds are different. This is a technology limitation. Usually one is expected to download more data then upload it. So the technology is designed in such a way that users get more downlink capacity. With such a high speeds every body can surf internet pretty well. But the story doesn’t end here.
