4G TECHNOLOGY

1G:FIRST GENERATION 1G (or 1-G) refers to the first-generation of wireless telephone technology These are the analog telecommunications standards that were introduced in the 1980s

2G:SECOND GENERATION By the end of the year 1980 the digital telecommunication standards were developed. These systems provided better voice quality with higher capacity which even costed low.

3G:THIRD GENERATION IMT-2000 is better known as 3G 3G provide faster communication services which include: voice ,fax internet. Broadband capabilities to support greater numbers of voice and video calls.

4G:FOURTH GENERATION Support Interactive services like Video Conferencing, Wireles Internet,etc. The networks will be all IP networks based on IPv6. 4G networks provide speeds of 100 Mbps while moving and 1 Gbps while stationary.

TECHNOLOGY USED IN 4G COMMUNICATION SYSTEM The infrastructure for 4G will be only packet-based (all-IP). But there is suggestion to have an open Internet platform. The 4G technology en suite with 802.16e mobile version of WiMax (also known as WiBro), and HC-SDMA, Adoptive Modulation and coding (AMC),Adaptive Hybrid ARQ , MIMO AND OFDM and Open distributed Ad- Hoc Wireless Network .

1st generation computer

History of 4G Analog Digital In wireless cellular phone networks, radio towers pick up signals from handsets and connect them to the telephone system. First-generation or 1G cell phones used insecure analog signals between the handset and the radio towers. Developed in the 1980s, they allowed voice communication only and there was no single recognized standard Digital The first digitally encrypted cellular telephones became commercially available in Finland in 1991. As well as a more secure voice technology, second-generation phones could transmit and receive data such as text messages.

3rd generation computer

History of 4G Mobile Internet New third-generation standards for mobile telecommunications came into effect from 2000 onwards. The standards specify that 3G services must allow simultaneous speech and data transfers and peak data rates of at least 200 kilobits per second. Mobile Internet access and video calls became possible, followed by mobile broadband service to laptops and advanced mobile phones 4G A cellular system claiming to be fourth-generation must provide high-speed data transfers in both mobile and stationary situations. The International Telecommunication Union defined specific standards in October 2010. Although several carriers claim to have 4G systems, as of November 2010 none of them complies with the latest specification.

4G Challenges 4G is Fabricated to lower the Power consumption Cost

4G 3G 2G 1G 4G POSSIBILITIES 0G Enhanced Mobile Gaming 4G enhanced wireless capabilities that deliver mobile gaming interaction with latency less than five milliseconds. Play online multiplayer games while traveling at high speeds or sitting outside. 3G 2G 1G 0G

4G POSSIBILITIES Virtual Presence For example, decide if you want to personally respond when someone rings your front door while you are away from home. 4G 3G 2G 1G 0G

4G BROADBAND ACCESS IN REMOTE LOCATIONS 4G networks will provide a wireless alternative for broadband access to residential and business customers. In addition, 4G will provide the first opportunity for broadband access in remote locations without an infrastructure to support cable 3G 2G 1G 0G

Software-Defined Radio (SDR) SDR is one form of OWA (open wireless architecture). Since 4G is a collection of wireless standards, the final form of a 4G device will constitute various standards. This can be efficiently realized using SDR technology, which is categorized to the area of the radio convergence.
