2G Vs 3G services

3G represents the next step in the evolution of mobile telephony, offering markedly greater capacity and efficiency than the current 2G systems.

While 2G is focused on voice, 3G supports high-speed data of at least 144 kbps enabling broadband Internet access on the mobile, and "triple play" features like mobile TV and converged communication services.

Similarly, 3G will allow operators to enhance their capacities for voice traffic as well. Currently, key operators are facing severe 2G spectrum crunch in top 20-30 cities which is hampering their future growth. As the government has indicated that it has limited spectrum left for 2G services.

Also, while 3G is good for data services, it is also three times more efficient than current technologies in packing in subscribers.
