Abstract

We propose and describe an efficient wireless local access system for high-speed Internet users at home, school or business. This system takes advantage of the asymmetric traffic characteristic of popular Internet services (such as web search and ftp) to realize very high system capacity and very low delay response time to users due to effective statistical multiplexing. Specifically, the system provides subscribers with 10-Mb/s downlink (base-to-user) and 2-Mb/s uplink (user-to-base) speeds by using a three-cell frequency reuse plan with packet-mode sectorized base-station antennas. Using the 2-GHz band as an example, the cell radius can be up to 5 miles, and the total number of active users in each cell can be in excess of 15,000 with delay bounds commensurate with today's typical web services. Our design discussions include considerations for radio propagation, link budget, inter-cell interference, signal-to-interference ratio, high-speed modem, base-station gateway and capacity estimates.
