TECHNICAL DEFINATON The International Telecommunications Union- Radio communications sector (ITU-R). The International Mobile Telecommunications Advanced (IMT-Advanced). Mobile WiMAX. LTE.

Mobile WiMAX Release 2 (also known as WirelessMAN-Advanced or IEEE m'). LTE Advanced (LTE-A). Internet Protocol (IP) based communication such as IP telephony. Multiple-input multiple-output (MIMO). The term "generation".

HISTORY AND PRE-4G TECHNOLOGY The Defense Advanced Research Projects Agency (DARPA). New mobile generations have appeared about every ten years since the first move from 1981 analog (1G) to digital (2G) transmission in 1992.

This was followed, in 2001, by 3G multi- media support, spread spectrum transmission and at least 200 kbit/s peak bitrate, in 2011/2012 was expected to be followed by "real" 4G, which refers to all-Internet Protocol (IP) packet-switched networks giving Ultra Mobile Broadband (gigabit speed) access.

1G  Wireless cellular systems, introduced in the early 1980s  Use analog transmission, and are primarily intended for voice.  These networks are very slow  Speed less than 1 kilobits per second (Kbps)

2G  wireless cellular systems, introduced in the late 1980s  use digital transmission and are also intended primarily for speech.  they do support fax and services at low bit- rate (8 to 9 Kbps) data transmissions.  The high-tier 2G systems use GSM and the low-tier system is intended for low-cost, low-power, low- mobility personal communication systems.

3G Services include:  Global roaming  Superior voice quality and video conference  Data always add–on services ( , personal organizer, etc.)  Information for web surfing, music, news, corporate intranet, transportation service etc.  Purchasing – on-line shopping / banking, ticketing, gambling, games, etc.

 Transmission speeds from 125kbps to 2Mbps  In 2005, 3G is ready to live up to its performance in computer networking (WCDMA, WLAN and Bluetooth) and mobile devices area (cell phone and GPS)

3G Relatively lower speed. uses both packet switching and circuit switching network nodes. The std. data speed specified by ITU is 384kbps in higher mobility and 2mbps in lower mobility. 4G Much higher speed than 3G. only packet switching infrastructure is used. The std. data speed specified by ITU is 100Mbps in higher mobility and 1Gbps in lower mobility.

IMT ADVANCED REQUIREMENT Be based on an all-IP packet switched network. Have peak data rates of up to approximately 100 Mbit/s for high mobility such as mobile access and up to approximately 1 Gbit/s for low mobility such as nomadic/local wireless access. Be able to dynamically share and use the network resources to support more simultaneous users per cell. Using scalable channel bandwidths of 5–20 MHz, optionally up to 40 MHz [

The ability to offer high quality of service for next generation multimedia support. In September 2009, the technology proposals were submitted to the International Telecommunication Union (ITU) as 4G candidates. Basically all proposals are based on two technologies: LTE Advanced standardized by the 3GPP m standardized by the IEEE (i.e. WiMAX)

Have peak link spectral efficiency of 15 bit/s/Hz in the downlink, and 6.75 bit/s/Hz in the uplink (meaning that 1 Gbit/s in the downlink should be possible over less than 67 MHz bandwidth). System spectral efficiency of up to 3 bit/s/Hz/cell in the downlink and 2.25 bit/s/Hz/cell for indoor usage. Smooth handovers across heterogeneous networks.

SYSTEM STANDARDS IMT-2000 compliant 4G standards. LTE Advanced. IEEE m or WirelessMAN- Advanced. Mobile WiMAX (IEEE e). LTE.

Case Study :-Remote Stroke Diagnostic Center  University of California, San Diego (UCSD) needed to diagnose and administer a specific life-saving drug remotely to counter and nullify the debilitating effects of a stroke.  The drug is effective only if administered in the first three hours from the onset of the stroke symptoms.

 The diagnosis is based on the performance of certain physical movements, so transmission and analysis of sheer numerical results accumulated from tests is not sufficient when the physician is at a remote location.  The drug is suitable only for a very specific type of stroke: the one caused by a blood clot. Administration of the drug in any other situation would heighten the stroke and make subsequent treatment extremely difficult.

The system is currently in operation and has already saved some lives. Eventually all community hospitals will participate in UCSD clinical trials that will utilize enhanced, broadband wireless Internet technology, dubbed the Multi-Media Telemedical Diagnostic
