Abstract
This paper describes a simple and low cost transceiver for indoor wireless LAN system to be operated in 60 GHz for ultra-high speed data (e.g. 156 Mbps) transmission, along with design of system parameters such as frequency selection, radio link parameters featuring very low RF power of 10 mW suitable to MMIC performances and high gain antennas. Without using route diversity and adaptive delay equalizers making up for shadowing and multipath reflection of RF signals, new layout of hub and user stations and line-of-sight transmission scheme are adopted. In addition, partially applied radio absorber helps effectively to reduce the undesired co-channel interference signal to the neglectful level, which system is named minimum delay spread (MDS0 local area network (LAN). This paper also presents the idea of effective applying absorber on ceiling which is derived from simulation and some useful measured data of absorbing construction materials, and presents main features of developed MMIC chip set workable in 60 GHz.
