India heads for 4G evolution by 2012
With 3G emerging as the next generation of mobile systems, India gets ready to embrace the 4G evolution, technology professionals said at the LTE India 2011 international conference organized by Bharat Exhibitions.
LTE (Long Term Evolution)or 4G would be the next big step towards a broadband wireless revolution by using core set up of the 2G/3G networks. This dramatically matured transition aims to deliver a unique consumer experience as the world forays into the 4G territory with about 380 million LTE subscribers and 80 plus LTE networks by 2015.
The LTE specification provides downlink peak rates of at least 100 Mbps, an uplink of at least 50 Mbps and RAN round-trip times of less than 10 ms. LTE supports scalable carrier bandwidths, from 1.4 MHz to 20 MHz and supports both frequency division duplexing (FDD) and time division duplexing (TDD).
The main advantages with LTE are high throughput, low latency, plug and play, FDD and TDD in the same platform, an improved end-user experience and a simple architecture resulting in low operating costs. LTE will also support seamless passing to cell towers with older network technology such as GSM, cdmaOne, UMTS, and CDMA2000.
Worldwide trials for the 100 Megabits per second LTE service had already started taking shape in 2010. In India, Qualcomm and Huawei had set up a trial network in Hyderabad. But hopefully, the technology would support only four or five operators provided they have a pan India reach.
Already with globally 18 launches with 208 network commitments, the LTE evolution will change the way people connect to communicate. Industry leaders suggested India could not afford to miss the universal broadband overage and auction was not the best way for the national imperative move forward.
But the widely acclaimed auction route may shift a vast amount of resources from the private sector to the government sector. Telecom broadband networks need to pool in sufficient resources and focus on greater active infrastructure sharing to restore the balance of dynamism in the spread of mobile broadband services.
LTE may emerge as a strong and well-defined data interface that promises a new reality by extending the support of local language services for the Indian consumers.
