This paper describes a new high-speed wireless LAN system in the 19-GHz band. This system features a maximum throughput of 15.2 Mbit/s, which is faster than Ethernet's. To achieve high speed wireless data transmission, we propose the new global scheduling multiple access (GSMA). This system consists of a control module (CM) and some user modules (UMS). One CM can communicate with up to ten UMs. This GSMA, in which all data transmission is managed in the CM, has both short-length and long-length frames, and concatenates multiple packets, so that it performs well with light traffic and heavy traffic: with minimal delay. For high-speed transmission and easy construction, DQPSK/differential detection is used as a modulation/demodulation scheme, and both FEC and ARQ are adopted as the error control method. In addition, as a countermeasure to shadowing and multipath fading, the CM has an omnibeam antenna, and each UM uses a 12-sector antenna, and sector selection diversity is carried out at the UM. This wireless LAN system is based on the RCR STD-34A Japanese radio system standard.
