4g Operators Will Need At Least 10mhz: Dot

Even as the policy for auctioning spectrum for 3G mobile services is yet to be finalised, the Department of Telecom is already thinking about the introduction of fourth generation technologies (4G) such as LTE (Long Term Evolution). The DoT has taken a view that each operator offering 4G technologies should be given at least 10 Mhz spectrum compared to just 5 Mhz for 3G services.

"4G technology, LTE Advance, may also come in India in 2.1 Ghz band, as 2.5 Ghz is mostly used for satellite-based networks. For this technology, the minimum channel size required is 10 Mhz. We need to cater for the introduction of this technology in the country," the DoT stated in a presentation to the Empowered Group of Ministers. Long Term Evolution is the next step of mobile evolution, designed to increase the capacity and speed of mobile telephone networks. Major mobile carriers in the United States and several carriers worldwide have announced plans to convert their networks to LTE.

LTE could allow data transfer rates to and from mobile devices between 15 and 100 times faster than 3G networks. The technology provides downlink peak rates of at least 100Mbps. However, the technology is still being developed globally. Companies including Ericsson and Nokia Siemens are working towards developing standards.

Mass deployment of this technology is expected only by 2012. In India most operators are looking to move to this technology by 2011, once they start making money on 3G services.

On right track

According to industry experts, the DoT is on the right track by identifying at least 10 Mhz for LTE. "LTE is an orthogonal frequency division multiplexing access (OFDMA) technology which requires higher quantum of bandwidth than CDMA technologies. WiMax is also an OFDMA technology and that is why the DoT has earmarked 20 Mhz bandwidth for it. OFDMA technologies increase efficiencies and offer high data speeds

only when there is adequate spectrum," said an industry expert.

Hi Hi what a joke

Even 3G is

[me_saket 73]

I like this idea,

this will help india to meet it's target "becomimg top country by 2020,"

And corrupted minister like A RAJA should be through away.

Thanks to DOT

4G threatens to spoil Govt's 3G party

NEW DELHI: As India dithers over a policy on 3G mobile telephony, US' Motorola wants to test the next level (4G) that could pour cold water on

the government's plan to raise Rs 35,000 crore from selling radio frequency for the existing version.

Motorola, which has tested the new next generation technology, called Long-Term Evolution (LTE), is all set to start trial services of 4G that can offer 70 MB per second (Mbps) download speeds on a mobile phone by the end of this year.

The company is likely to approach the Department of Telecom (DoT) for trial spectrum, Subhendu Mohanty, a senior executive with Networks Mobility Business, Motorola India, told PTI.

This development may, however, prompt operators planning to launch 3G telephony to wait and watch, thus spoiling the government's plan to mop up a whopping Rs 35,000 crore from auction of 3G spectrum.

Asked whether Motorola is talking to operators, Mohanty said: "We would like to have trial with the players but the technology can also be tested on our own systems." In fact, the DoT is also understood to have prepared a concept paper on the 4G and the issue may be discussed at length in the days to come. Besides Motorola, other telecom vendors are also in the process of trials, industry sources said. MORE

Motorola has become the first telecom vendor to complete throughput up to 70 Mbps, he said, adding that the LTE technology can be offered in 2.1-2.3 MHz spectrum band and the DoT is looking at the availability of this frequency.

On how superior and different the LTE would be from the 3G technology, Mohanty said the applications are growing very fast and with the data and video download explosion the performance of 3G technology will reduce and LTE would fill the gap.

When contacted, DoT officials declined to give any idea on when this (LTE or 4G) can be considered for commercial deployment, saying one needs to look into the availability of spectrum and also the viability of the services in Indian conditions.

According to sources, some of the operators may wait for this technology to become commercially available rather than investing in the 3G technology.

An empowered Group of Ministers has already been set up to frame policy on two most crucial aspects of 3G services - finalising the reserve price for auction of spectrum and number of slots to be auctioned in the first phase.

This is becoming interesting now!!

Now the smart mobile operators will not bid for 3G services now

So 2.75/EDGE technology is here to stay at least for 2 Years
