Commercial cellular wireless communications have a history of about 3 decades. Currently, the wireless industry is busy with the standardization of the 4th generation (4G) cellular networks, namely, LTE/LTE- Advanced and WIMAX 802.16m. The 4G standards are expected to be concluded in the next year or two. The early commercial deployments could initiate in subsequent years. With 4G networks, wireless internet connectivity will be faster and more affordable which will result in substantial increase in wireless internet usage. Since the 4G concepts have already moved to the standardization phase, we must begin to work on the building blocks of the next generation (which we refer to as 5G) wireless networks. These networks will facilitate the provision of omnipresent and affordable broadband with very high speed wireless connectivity. This paper aims at highlighting some of the key concepts and technologies which will facilitate the affordable provision of very high data rates with virtually ubiquitous coverage in 5G wireless networks. We refer to this goal as enabling the 4A?s paradigm i.e. any rate, anytime, anywhere and affordable. In particular, this paper focuses on the features such as broadband internet in mobile phones with a possibility to provide internet facility in the computer by just connecting the mobile and with a speed of 10Gbps and more. Techniques with certain advanced physical layer operations in the presence of advanced radio access network (RAN) architectures, we refer to this design principle as the “integrated cross-layer cross-network design”.
