4G soon to be in Indian market @gigabyte/sec

4g_network-300x292Pass over 3G, the Fourth Generation mobile phone technology, better known as Long Term Evolution (LTE) is already here.

3G utilized wi-max and wi-fi as separate wireless technologies, whereas 4G TECHNOLOGY is expected to coalesce these two technologies. Hence one can evaluate how efficient it would become when combining two extremely reliable technologies. 4G can greatly anticipate in evolving and advancing the pervasive computing. The aim of pervasive computing is to attach itself to every living space possible, so that human beings remain intact with the wireless technology intentionally and unintentionally. Therefore 4G will be able to connect various high speed networks together, which would  enable each one of us to carry digital devices even in dispersed locations.   The network operators worldwide would be able to deploy wireless mesh networks and make use of cognitive radio technology for widespread coverage and access.

How that future would appear, could be seen from the projection that by 2015, 6.3 billion people will be downloading  digital books every day, 50 per cent on laptops and the other 50 per cent on small devices like mobile phones.  The demand on laptop capacity would go up by 1000 per cent and on small devices by 10,000 per cent.  LTE would enable a  1GB file to be downloaded in your laptop quickly or upload a 500 MB file is less than minute through your mobile device

In INDIAN, BSNL has launched India’s first 4G service 4G WIMAX Broadband Services In KERLA on 4th June 2011.

AIRTEL launched India’s first 4G service, using LTE technology, in KOLKATA on April 10, 2012. Fourteen months prior to the official launch in Kolkata, a group consisting of China Mobile, Bharti Airtel and Softbank mobile came together, called Global TD-LTE Initiative (GTI) in Spain and they signed the commitment towards TD-LTE standards for the Asian region. It must be noted that Airtel’s 4G network does not support mainstream 4G phones such as Apple iPhone 5, Samsung Galaxy S III, Nokia Lumia 920 and others.

However “It would take next four to five years for the right eco-system for LTE to develop.”

India’s telecom minister Mr. Kapil Sibal has announced that Govt will conduct the auction for 700MHz spectrum by next year.

In an event to commission country’s first independent lab at Mumbai for measuring specific absorption rate (SAR) for mobile devices Mr. Sibal has told that Govt is going to auction 700MHz band (698-806 MHz) in any case by 2014.

It is almost certain that 700MHz band will be used for high speed connectivity via 4G. In United States LTE-FDD is widely deployed by Verizon over 700MHz band. The advantages of 700MHz band over earlier sold 2300MHz are several – 700MHz will provide more coverage, operators have to install lesser number of BTS and even can offer blanket coverage over the area. 700MHz can be best suitable for rural broadband.

It can be anticipated that the price of 700MHz band will be huge. Telecom sector is going through cash crisis, and who will buy it, that’s a big question??
