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, the authors must begin to work on the building blocks of the next generation wireless networks.
