What is mobile 4G network, 4G Mobiles, 4G features, Compare difference between 3G and 4G , 4G launch date

4G mobile is not yet established as an agreed set of standards, so its features are currently simply goals rather than requirements.4G which stands as Fourth Generation is the upcoming next generation technology which will wipe its predecessor 3G out of the surface of the world. The 4G technology has promised to offer widespread, complete and invulnerable all-IP (Internet Protocol) based services example of such services are high quality multimedia streaming, enhanced gaming services, super fast broadband Internet access, IP telephony and etc.

What is 4G mobile networks
The design is that 4G will be based on OFDM (Orthogonal Frequency Division Multiplexing), which is the key enabler of 4G technology. Other technological aspects of 4G are adaptive processing and smart antennas, both of which will be used in 3G networks and enhance rates when used in with OFDM.

Expected features of 4G Mobile network

The entire network would be packet switched (IP based). All switches would be digital. Higher bandwidths would be available which would make cheap data transfer possible. The network security would be much tighter. Also QoS will imrpove. More effecient algorithms at the Physical layer will reduce the Inter-channel Interference and Co-channel Interference. 100mbps would be the normal data rate for the users who are not stationary and moving at high speeds and 1gbps would be the maximum data rate when the user is indoor or at a fixed position.Bandwidth flexibility, between 5 to 20 mega hertz maximum up to 40 mega hertz. Worldwide roaming over multiple networks and flawless connectivity

Feature of 4G mobile technology

-         Based on open wireless architecture (OWA).

-         Congregate several RTTs (radio transmission technologies) in one one device.

-         The device would enable detachable unused modules.

-         Amalgamate home phone, office phone and mobile phone into one common Personal device.
