CDMA/HDR: A bandwidth-efficient high-speed wireless data service for nomadic users

This article presents an approach to providing very high-data-rate downstre am Internet access by nomadic users within the current CDMA physical layer architecture. Means for considerably increasing throughput by optimizing pa cket data protocols and by other network and coding techniques are presente d and supported by simulations and laboratory measurements. The network arc hitecture, based on Internet protocols adapted to the mobile environment, i s described, followed by a brief discussion of economic considerations in c omparison to cable and DSL services.
