Abstract

Consumers demand more from their technology. With the advent of the Internet, the most-wanted feature is better, faster access to information. To support a powerful system, we need pervasive, high-speed wireless connectivity. A number of technologies currently exist to provide users with high-speed digital wireless connectivity; the goal is long-range, high-speed wireless, which for the purposes of this report will be called 4G, for fourth-generation wireless system. Fourth-generation wireless needs to be standardized due to its enticing advantages to both users’ and providers. The first release of the 3GPP Long Term Evolution (LTE) standard does not completely fulfill the ITU 4G requirements called IMT-Advanced. First release LTE is not backwards compatible with 3G, but is a pre-4G or 3.9G technology, however sometimes branded "4G" by the service providers. Its evolution LTE Advanced is a 4G technology. WiMAX is another technology verging on or marketed as 4G.The proposal for 5G technologies aims to provide very high data-rates, massive number of devices connectivity, very high reliability and low latencies. Therefore, efforts are underway to consider beyond state of-the-art protocols and mechanisms for wireless communication. Thus, the next generation of wireless communication is expected to meet the demands of various challenging use cases that go far beyond distribution of voice, video and data. Therefore, this paper aims to present the solutions that address the challenges wireless communication systems are facing.
