4G Definition

4G is not one defined technology or standard, but rather a collection of technologies at creating fully packet-switched networks optimized for data.

4G Networks are projected to provide speed of 100Mbps while moving and 1Gbps while stationary.

What is 4G? Fourth Generation Technology

Faster and more reliable 100 Mb/s Lower cost than previous generations Multi-standard wireless system Bluetooth, Wired, Wireless Ad Hoc Networking IPv6 Core OFDM used instead of CDMA Potentially IEEE standard 802.11n Most information is proprietary

Communication Architecture Personal Layer Gateway:

devices that connect to upper layers; cell phone, fax, voice, data modem, MP3 players, PDAs

Info-Sensor layer: environmental sensors

Fiber-optic wire layer: high speed subterranean labyrinth of fiber optic cables

and repeaters

Ad-Hoc Networks

Spontaneous self organization

of networks of devices

Not necessarily connected to

internet

4G will create hybrid wireless

networks using Ad Hoc

networks

Form of mesh networking–Very

reliable

Enhance Mobile Gaming

Experience enhance wireless capabilities that deliver mobile gaming interaction with less than five seconds

Play online multi player games while traveling at high speeds or sitting outside

Broadband Access In Remote Areas

4G will provide a wireless alternative for broadband access

It will provide first opportunity for broadband access in remote locations without an infrastructure to support cable or DSL access.

LTE (Long-Term Evolution)

Specification managed by 3GPP organization 3rd Generation Partnership Project Scope to create global 3G spec based on GSM

New LTE specification in Release 8, 4G Scope

4G LTE

An acronym for Long Term Evolution, LTE is a 4G wireless communications standard developed by the 3rd Generation Partnership Project (3GPP).

designed to provide up to 10x the speeds of 3G networks for mobile devices such as smartphones, tablets, netbooks, notebooks & wireless hotspots.

4G LTE is one of several competing 4G standards along with Ultra Mobile Broadband (UMB) & WiMax (IEEE 802.16). 

4G LTE Advance

LTE Advanced is a mobile communication standard and a major enhancement of the Long Term Evolution (LTE) standard. It was formally submitted as a candidate 4G system toITU-T in late 2009 as meeting the requirements of the IMT-Advanced standard, and was standardized by the 3rd Generation Partnership Project (3GPP) in March 2011 as 3GPP Release 10

The LTE format was first proposed by NTT DoCoMo of Japan and has been adopted as the international standard.

The first commercial services were launched in Sweden and Norway in December 2009 followed by the United States and Japan in 2010.

The work by 3GPP to define a 4G candidate radio interface technology started in Release 9 with the study phase for LTE-Advanced. Being described as a 3.9G (beyond 3G but pre-4G).
