4G Trials begins in india

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. Other operators 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
one, it will be able to use existing network infrastructure with slight modifications; and second, 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.
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.
