INTRODUCTIONWhat is 4G4G is a term used to refer to the next level of mobile broadband 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, because smartphones and mobile devices are different. Modified conceivable applications include mobile network access, telephone scientific discipline, diversion services, high-definition mobile television, video conferencing, 3D television, and cloud computing. Two candidate 4G systems used custom commercial mobile WiMAX (first used in Asian countries in 2006) and therefore the first version – the future of custom Evolution (LTE) (in the capital and the country's capital Norge, Sverige since 2009). But debate whether the first version should be considered 4G or not, stated in the technical definition section below. The main competitors are LTE and WiMAX, both are IP-based networks and built from the same technology. but are not compatible. Sprint and Clearwire's 4G WiMAX service is now available in the US, while Verizon and AT&T have committed to LTE and tested their 4G network. In the United States, Sprint (formerly Clearwire) has deployed a WiMAX mobile network since 2008, and MetroPCS is the major carriers will provide LTE services in 2010. USB wireless modems in the market since the beginning, while WiMAX smartphones have been on the market since 2010 and LTE smartphones since 2011. Instruments developed for different continents are not directly compatible, due to current differences (April 2012) are not on the market for the Euro market. APPLICATION OF TECHNOLOGY How does it work? If you travel to other websites you will find many vague technical descriptions of what...... middle of paper ..... .o the kernel through the S1 interface. It is supposed to speed up installation time and reduce time to abandonment. Setup time is extremely necessary for real-time information services like online gambling, making the decision even more difficult. Figure 1.1 Where is 4G service available? Our guide explores the usability of 4G in all countries and helps you understand this new wireless broadband technology together. with suppliers, compatible instruments and network deployment. 4G pioneer EE was recently joined by O2, Vodafone and the latest Tesco Mobile to bring the super-fast network to more than seventieth of the population. As coverage expands and competition heats up, let's check if you can all get 4G wherever you are. If you want to check your coverage for 4G service in your area, you can check online..
