What is LTE : 

What is LTE LTE stands for Long Term Evolution, used for the generation evolution aspect of wireless communication LTE started with the advancement of 3G standard in 2006 There are two versions of LTE – basic, and Advanced Basic LTE falls under 3.5G Advanced LTE falls under 4G By Prattzz http://prattzzstechblog.blogspot.com/

What is 4G : 

What is 4G 4G is the fourth generation of cellular wireless standards. It is a successor to 3G and 2G families of standards Data Speeds upto 1Gbit/sec approx All 4G devices are based on IP Packet switched network Dynamically share and utilize the network resources to support more simultaneous users per cell Smooth handovers across heterogeneous networks Ability to offer high quality of service for next generation multimedia support Support for HDTV under development By Prattzz http://prattzzstechblog.blogspot.com/

Relationship between LTE and 4G : 

Relationship between LTE and 4G The evolution of 3G started the development of a new series of tansition standards such as 3GPP(3rd Generation Partnership Project) and LTE LTE technologies enable the transition from 3G to 4G LTE data speeds start at 100Mb/s whereas 4G starts at 1000Mb/s 3G May/May not be LTE, but LTE is 4G By Prattzz http://prattzzstechblog.blogspot.com/

LTE Advanced : 

LTE Advanced 3G 4 We are here Smooth transition from 3G to 4G LTE-Advanced to be the main feature of 3GPP Release 10 LTE LTE-Advanced 3G 4G By Prattzz http://prattzzstechblog.blogspot.com/

Standards for 4G : 

Standards for 4G Data Speeds upto 1000Mbit/s IEEE 802.16m (Wi-Max) for wireless internet IPv6 Support Only packet switching used unlike previous generations OFDMA(Orthogonal Frequency Division Multiple Access) and MIMO(Multiple In Multiple Out, e.g multiple antennas and dynamic channel allocation) replace CDMA spread spectrum radio technology By Prattzz http://prattzzstechblog.blogspot.com/

Technical Aspects(4G) : 

Technical Aspects(4G) Packet switching replaces circuit switching as IP becomes mandatory for 4G devices IEEE 802.16e/m included for data IP-based femtocells (home nodes connected to fixed Internet broadband infrastructure) OFDMA used for Wi-Max IPv6 removes the need for network address translation (NAT), a method of sharing a limited number of addresses among a larger group of devices Finalisation still awaited of some standards By Prattzz http://prattzzstechblog.blogspot.com/
