Abstract

The higher data rate (up to 100 Mbps) and strict quality of service (QoS) requirements of multimedia applications may not be fully supported over the current cellular networks. Since the transmit power of a data link increases with the data rate when a specific link quality is maintained, providing very high data rate services will require either the expenditure of high amounts of power or limiting the link to a short distance. Therefore, there are interests on investigating next-generation cellular network structures for higher data rates and coverage as well as scalability in addition to the continuing research on advanced wireless communication technologies. This decade is expected to bring many exciting changes to the wireless communication networks, enabling mobile broadband Internet services on a wide range of user devices. These changes are part of the wireless networks, evolution to fourth generation (4G) technologies. An overview of next generation cellular network is provided in this work including background and integration of cellular and Internet services. Next section deals with multihop cellular networks (MCNs) together with load balancing and cooperation in MCNs. Finally, the third part describes 4G cellular standards and reports on some research issues in this area.
