4G is short for Fourth (4th) Generation Technology.4G Technology is basically the extension in the 3G technology with more bandwidth and services offers in the 3G. 4G Technology offers high data rates that will generate new trends for the market and prospects for established as well as for new telecommunication businesses.
The 4th generation (4G) mobile technology is becoming the emerging solution to drive the new growth of the industry, and help foster state-of-the-art technology, novel partnership arrangements or transformational business models. Our 4G events, the world’s leading platforms of the 4G industry, are steadfast in supporting the industry and confident in the ability to uncover and advance the opportunities. The future trend is same: Convergence among fixed, mobile and wireless communications. No single wireless radio transmission technology (RTT) can do both broadband high-speed data-rate and seamless mobility, and therefore we need multiple RTTs to complement each other in any optimal way to ensure the information is delivered to the mobile user in a more cost-effective way and in a more spectrum-efficient way. A 4G system is expected to provide a comprehensive and secure all-IP based mobile broadband solution to laptop computer wireless modems, Smartphone’s, and other mobile devices. Facilities such as ultra-broadband Internet access, IP telephony, gaming services, and streamed multimedia may be provided to users.4G as a shorthand way to describe those advanced cellular technologies that, among other things, are based on or employ wide channel OFDMA and SC-FDE technologies, MIMO transmission and an all-IP based architecture. The WiMAX provides speed up to 128mbps of downloading and for uploading it provides 56mbps, whereas LTE showed in an early implementation speed up to 100mbps downloading and 50 mbps uploading. While WiMAX on the other hand is an IEEE standard,also ITU doesn’t considered WiMAX a true 4G technology because it is not up to the specifications that ITU put forth.
