4G Long Term Evolution of Sprint in 2012

Sprint Nextel announses its 4G Long Term Evolution (LTE) on early 2012 . Eventhough they are not aware of how the market will accept, Sprint is now testings its 4Gin selected area. As Sprint has planned its 4G long back , they said there wont be much investment on this product.But with this they are pretty sure that the quality of this will be much better than any other product so far in the market. 
Sprint's 4G LTE network would give the carrier a network on par with Verizon. Sprint will officially announse more details and launch of its 4G in October . Even they are expected to getting ready for its iPhone , which was the monopoly of AT&T and latter by Verizon. With the acqusition of Nextel , who owns the D-block spectrum , will be used for this. . The whole project, which is expected to cost $4 billion to $5 billion

What is LTE?
Long Term Evolution (LTE) is a standard for wireless communication of high-speed data and is based upon GSM/EDGE and UMTS/HSPA network technologies . LTE is the brand name for emerging and developed technologies that comprise the existing 3G and 4G networksThe goal of LTE is to increase the capacity and speed of wireless data networks utilizing cutting-edge hardware and Digital signal processing techniques .

Features of LTE include an all-IP flat network architecture, end-to-end QoS including provisions for low-latency communications, peak download rates nearing 300 mbps and upload rates of 75 mbps, capacity exceeding 200 active users per cell, the ability to manage fast-moving mobiles, and support for multi-cast and broadcast streams.Peak download rates of 299.6 Mbit/s for 4x4 antennas, and 150.8 Mbit/s for 2x2 antennas (using 20 MHz of spectrum).Peak upload rates of 75.4 Mbit/s for every 20 MHz of spectrum using a single antenna.

The LTE standard can be used with many different frequency bands. There are planned 700 and 1700 MHz in North America; 900, 1800, 2600 MHz in Europe; 1800 and 2600 MHz in Asia; and 1800 MHz in Australia.The combination of LTE’s increased spectral efficiency and flexibility, added capacity, and simpler network architecture should offer a very cost effective value proposition.
