What is 4G
4G is a term used to refer to the next level in high-speed mobile technology that will be used to replace the current 3G network. A 4G system provide ultra-clean mobile broadband, such as a laptop with a wireless USB modem, for smartphone and mobile device are different. Conceivable application amended embrace mobile net access, phones scientific discipline, diversion services, high definition mobile TV, video conferencing, 3D TV and cloud computing.
Two candidate 4G system used custom commercial Mobile WiMAX (first used in Asian countries in 2006) and therefore the first release – the future of Evolution (LTE) custom ( in the capital and the country’s capital Norge, Sverige since 2009). But have debate if the first – release version should be thought – about to be 4G or not, has stated in the technical definition section below.
The top contenders are LTE and WiMAX, both are IP – based networks are built from the same technology, but are not compatible. Sprint and Clearwire’s 4G WiMAX service is now available in U.S, while Verizon and AT & T has committed to use LTE and tested on their 4G network.

4G Technology is currently being developed and is looking to be implemented in 2012 – 2015. The technologies most commonly being observed by the industry are the WiMAX 2 and LTE Advanced networks which will provide faster internet service in the future.
