Broadband radio access integrated network (BRAIN) in MM-wave band: indoor wireless LAN prototype

Recently, BRAIN (broadband radio access integrated network in millimeter-wave band) is proposed as a new system concept for millimeter-wave communications. BRAIN will serve as a high-speed wireless LAN in indoor environments and as the last hop of FTTC (fiber to the curb) in outdoor environments. In the Communications Research Laboratory, an indoor LAN prototype of BRAIN including an access point and 6 remote stations was developed successfully. A wireless ATM oriented integrated transmission protocol called RS-ISMA (slotted idle signal multiple access with reservation) was implemented and thus the system can transmit multimedia traffic including voice/data/video. In this paper, we introduce in detail the system profiles of the prototype including system design, configuration, and implementation. Finally, an experimental schedule for multimedia transmission via wireless ATM is described.
