Vocabulary

Replace : Take the place of

Long Term Evolution (LTE) : The latest high-speed cellular data transmission network

Deployed : Bring into effective action

Compatible : (of two things) Able to exist or occur together without problems or conflict.

Wireless : Using radio, microwaves, etc. (as opposed to wires or cables) to transmit signals.



4G is the term used to refer to the next wave of high-speed mobile technologies that will be used to replace current 3G networks

Long Term Evolution (LTE) technology is sometimes called 3.9G or Super 3G and has been developed by the Third Generation Partnership Project (3GPP) as an improvement to the current Universal MobileTelecommunications System (UMTS).

Two 4G candidate systems are commercially deployed: the Mobile WiMAX standard (first used in South Korea in 2007), and the first-release Long Term Evolution (LTE) standard (in Oslo, Norway and Stockholm, Sweden since 2009

Metro PCS became the first operator to offer LTE service in 2010. USB wireless modems were among the first devices able to access these networks, with WiMAX smart phones becoming available during 2010, and LTE smart phones arriving in 2011.

The consumer should note that 3G and 4G equipment made for other continents are not always compatible, because of different frequency bands. Mobile WiMAX is currently (April 2012) not available for the European market.




EVOLUTION FRON 1G TO 4G SYSTEM

1g Wireless System: Developed in 1980s and completed in early 1990's

2g Wireless System: 2g phase began in the 1990's and much of this technology is still in use.

3g Wireless system: It was developed in the late 1990's until present day, Japan is the first country having introduced 3g nationally




4G HARDWARE

ultra wide band network

wideband technology, or UWB, is an advanced transmission technology that can be used in the implementation of a 4G network

Smart Antennas

Multiple "smart antennas" can be employed to help find, tune, and turn up signal information

NEXT GENERATION APPLICATIONS PROCESSORS

The amount of processing performance needed to deliver these new 4G applications will be large. Integrated, multi-core architectures that deliver microprocessors and DSPs on a single chip will be critical to 4G’s success.

Products such as TI’s OMAP applications processors enable ore sophisticated and intuitive user’s interfaces and provide a web browsing experience similar to traditional PCs.

The big challenge in brining 4G to the market will be using the right applications processors as well as modem and power management technologies to deliver the performance, size and battery life that consumers demand. The path is clear to bring 4G to reality and deliver compelling application and performance that will pave the way for the future of wireless.
