General Information:
fourth generation 4G, is the fourth generation of mobile telecommunications technology, well yes it's advance of 3G. It was developed by two 4G candidate systems are the
Mobile WiMAX standard ( 2007) &
first-release Long Term Evolution (2009)
WiMAX smart phones becoming available during 2010,
LTE smart phones arriving in 2011. 3G and 4G equipment
4G has a quality to supply 3D television, smart gaming, HD gaming, cloud computing, along with that even when you download OR surf on INTERNET you will get 11x speed. than 3G.
it will up to 50mb/s -100mb/s . 4G has a capability to proven your experience highly smooth like touch & open. 4G technical requirements is different than 3G Read below for more.. currently in
US 4G system enales with 4G LTE system and where 4G is not available " 3G " is helping hand.
Technical Scenario:
Setting peak speed requirements for 4G service at 100 megabits per second (Mbit/s) for high mobility communication (such as from trains and cars) and 1 gigabit per second (Gbit/s) for low mobility communication (such as pedestrians and stationary users).
As seen below, the spread spectrum radio technology used in 3G systems, is useless in all 4G candidate systems and replaced by OFDMA multi-carriertransmission and other frequency-domain equalization (FDE) schemes, making it possible to transfer very high bit rates despite extensive multi-path radio propagation (echoes). The peak bit rate is further improved by smart antenna arrays for multiple-input multiple-output (MIMO) communications.
Scopes:
The renovation of the generations generally refers to a change in the fundamental nature of the service, non-backwards-compatible transmission technology, higher peak bit rates, new frequency bands, wider channel frequency bandwidth in Hertz, and higher capacity for many simultaneous data transfers (higher system spectral efficiency in bit/second/Hertz/site).
