Globally, a number of countries are testing 4G after implementing 3G. But India, which can claim an international telecom presence, is yet to log on to 3G. Leapfrogging to 4G would prove to be a technology advantage for operators, since the 4G technology is 10 times more spectral efficient. More to the point, the 3G frequency bands identified by the ministry of communications and IT are compatible to roll out 4G services.
JS Deepak, joint secretary, department of telecom says, “4G frequency bands or Long Term Evolution (LTE) is under consideration of his department. He said a study is underway on the 700 MHz frequency band to examine if it could be used for WiMax or 4G.” The government has taken a ‘technology neutral stand’ on the spectrum to be allocated for 3G services. This could be first initiative to open a window towards 4G.
The LTE version 10, which is considered to be 4G, is being designed and will be available by the end of 2010. The present day LTE under implementation is considered as 3.9G. Since the spectrum for 3G will be available for private operators by August 2010, it would be the right time for India to go for 4G, as the equipment for 4G will be available by end 2010. Union minister for communications and IT A Raja has said allotment of spectrum to maintain level playing field will be done by August 2010.”
Former Trai advisor Satyen Gupta said India should leapfrog to 4G and skip 3G, as there has been a delay in the auction of the spectrum.
Number of 4G subscribers worldwide is expected to exceed 90 million in 2013.
