INTRODUCTION What is 4G4G 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 provides ultra-clean mobile broadband, like a laptop with a wireless USB modem, for smartphones and mobile devices are different. Possible modified applications include mobile network access, telephone scientific discipline, diversion services, mobile high-definition TV, video conferencing, 3D TV and cloud computing. Two candidate 4G systems used customized commercial Mobile WiMAX (first used in Asian countries in 2006) and then the first version – the future of evolution (LTE) customized (in the country's capital and capital Norge, Sverige since 2009). But debate whether the first release version should be thought of as 4G or not, stated in the technical definitions section below. The main contenders are LTE and WiMAX, both are IP-based networks built with the same technology, but they are not compatible. Sprint and Clearwire's 4G WiMAX service is now available in the US, while Verizon and AT&T have committed to using LTE and tested on their 4G network. In the United States, Sprint (formerly Clearwire) has been deploying the WiMAX mobile network since 2008, and MetroPCS is the leading service carrier to provide LTE services in 2010. USB wireless modems have been on the market since the beginning, while WiMAX smartphones are on the market since 2010, and LTE Smartphones since 2011. The equipment developed for the various continents are not directly compatible, due to the current differences (April 2012) they are not in the market for the euro market.THE APPLICATION OF THE TECHNOLOGYHow does it work?If you visit other websites you will find many vague technical descriptions of what... middle of paper... .or the core via the S1 interface. It should speed up installation time and reduce the time it takes to opt out. Setup time is extremely necessary for real-time information services such as online gambling, further giving up the decision. Figure 1.1Where is the 4G service available? Our guide explores the practicality of 4G across the country and helps you feel together this new wireless broadband technology with providers, compatible tools and network implementation. The 4G pioneer, EE, has recently been joined by O2, Vodafone and most recently Tesco Mobile to bring the super-fast network to over seventieth of the population. As coverage spreads and competition gets more intense, we're checking to see if you can all get 4G wherever you are.
