Aircel, Huawei and Qualcomm have successfully tested a dongle which works on existing 3G, GSM and CDMA networks, apart from the newer LTE (4G) TDD and FDD networks. Otheroperators are also conducting trials.Operators are preparing to launch 4G networks, which will bring down the cost and will work at higher speeds.
The reason for the low cost of 4G networks is two-fold:
1.) it will be able to use existing network infrastructure with slight modifications; and
2.) spectrum for 4G network was licensed to operators at a much lower cost (AS WE EXPECTED)compared to 3G network.
LTE can bring speeds of up to 100 Mbps download and 30 Mbps upload, while WiMAX, which is currently being used to connect rural Indian villages, delivers 40 Mbps download speeds.
(Sample 4G Speed Boston)
While Reliance bagged spectrum in all 22 circles, Airtel got licences for four circles, Aircel for eight, Tikona in five circles, and Qualcomm (which is in the market to promote LTE) also bagged spectrum in four circles. BSNL and MTNL had got spectrum even before the auction but have so far launched WiMax in very few locations.
The problem right now is that devices supporting LTE TDD (the version of LTE that will be deployed in India), are not available right now. But that problem is soon going to become history. Qualcomm has confirmed that LTE devices will be available in bulk by the end of the year. More than 70 percent handsets worldwide use Qualcomm chipsets.
SOON WE EXPECT ALL NETWORKS WILL LAUNCH 4G
