A Radio Multiplexing Architecture for High Throughput Point to Multipoint Wireless Networks

WiFi-based point-to-multipoint systems are a cost-effective solution for providing high-bandwidth connectivity to remote rural regions. However, current point-to-multipoint deployments are hampered by several challenges. Their capacity to support a large number of clients simply by increasing the number of radios at the base station is limited because space restrictions on radio towers bound the number of antennas that can be installed at one physical location. Also the limited availability of wireless channels restricts the number of clients that can be simultaneously supported by a base station at any point of time. In this paper, we explore high-throughput architectures for point-to-multipoint networks. We show how we can increase the number of radios at the base station without increasin
