Implementation of an experimental 384 kb/s radio link for high-speed Internet access

Interest in wireless high-speed access to wide area data networks has grown considerably, fuelled by the simultaneous development of the high-speed wired data networks, wide-spread availability of powerful mobile computing devices, rapidly dropping prices for increasingly sophisticated electronic devices, plus the global deployment of wireless voice systems. For many users, high-mobility wireless data access at near-LAN rates is likely to be an attractive option. Unfortunately, the harsh radio environment creates significant challenges when trying to provide high-speed access, especially if high-mobility and wide-area availability are expected. This paper describes an experimental implementation of a 1900 MHz OFDM radio link designed to provide 384 kb/s data link in representative mobile cellular-like channels
