India has completed the distribution of ultra-high-speed third generation (3G) mobile phone spectrum and winner for the 3G spectrum include Essar, Vodafone, Bharti Air-tel, R-Com, Tele- Services Tata, Idea Cellular and S-Tel. These mobile phones and Internet service providers are eager to display their latest technologies and mobile Internet in India this year. The winners of the 3G spectrum have already made an announcement that they are almost ready to launch their services and are in the final phase of the same thing.

India plans to organize an auction of ultra-high-speed fourth generation (4G) mobile spectrum in the year 2011.  Telecom Regulatory Authority of India (TRAI) has already announced to begun the process of pre- consultation for the sale of 4G spectrum. These 4G allows more data to be transferred from the 3G and higher speeds.

What is 2G mobile technology generation that is currently available in India?
Second generation (2G) network is a narrow band analog wireless and what can be voice calls, limited the semi-global installation and can send text messages. These services are provided with a switching circuit. While 2G narrowband wireless digital network is used. It brings more clarity to the conversation. The latest technology such as GPRS is not available in the second generation (2G). Under the current second generation mobile technology (2G) both transmission and reception of the mobile signal, the international telecommunications at reasonable speeds is not possible. Present holders of 2G GSM spectrum allocation in India have different circle.

 3G mobile generation for which the spectrum allocated to service providers  intend to offer its services soon in India. Third generation (3G) wireless network Wide Brand is used which increases clarity and gives perfection like that of a real conversation. The data is sent by a technology called packet switching. Voice calls are interpreted by circuit switching. With the support of 3G, we can access many new services such as global roaming, contact a person located in any part of the world and can even send messages too. It brings clarity of voice and can speak without any disturbance. Third generation (3G) offering entertainment such as Fast Communication, Internet, mobile TV, video conferencing, video calls, Multi Media Messaging Service (MMS), 3D games, multiplayer etc. with 3G phones is possible.

Under third-generation technology (3G), both transmission and reception of signals in the mobile speed of 60 mph is reached. India has recently awarded 3G spectrum. Service providers and mobile Internet technology that have won and were awarded 3G spectrum include Vodafone Essar, Bharti, Airtel, RCOM, Tata Tele-services, Idea Cellular and Stel. These service providers are eager to display their latest technologies and mobile Internet in India. The winners of the 3G spectrum have already made an announcement that they are almost ready to launch their services and are in the final phase of the same thing.

The Access Service License Unified (UASL) agreement was also amended by the Department of Telecommunications of India to include services of 3G, which will pave the way for the release of high speed Internet through mobile installation by the winners. Installing high-speed Internet in rural India is still missing with 2G mobile technology. And more than 900 million people in India are based in rural areas. 3G will bring changes in everything connected to the Internet in rural India? All these courses are to improve dramatically, perhaps beyond the imagination in near future in India.

What generation 4G mobile technology for which the consultation process for the sale of spectrum launched in India? The fourth generation mobile technology has made possible more than one gigabit per second download speed, while you access the Internet through wireless means! The 4G mobile technology is a next generation network that provides rapid access to data, unified messaging and multimedia broadband download speeds of 100 megabits per second. More bluntly, 4G allows you to download a HD movie in less than 30 seconds!

How can you tell if he / she use this kind of thing 4G or 3G right? Well, mobile technology with Internet service must satisfy the speed of any technology that claims to be 4G. The specification list of data transfer rates than the minimum proposed network should have 4G wireless communication standard. It has a nominal rate of data for 100 Mbit / s while the client physically moves at high speeds over the station and 1 Gbit / s while the client and station are in relatively fixed positions. It means the rate of data downloads at least 100 Mbit / s between any two points in the world. It must have a flexible bandwidth channels between 5 and 20 MHz, possibly up to 40 MHz. It must be linked Peak spectral efficiency of 15 bps / Hz in the downlink and 6.75 bps / Hz in the uplink (which means that 1 Gbit / s downlink should be possible less than 67 MHz bandwidth)

While India switch to 4G networks, cloud computing services became possible for everyone. That means equal rights to 900 million rural people in India for international telecommunications and Internet service. The major challenge facing these applications is not the technology itself, but as networks - the bottlenecks of information.
