The indoor radio channel at 5.2 GHz: prediction by means of ray tracing and measurements

A new radio access network archilecture for a mobile broadband system is introduced that uses Fixed Wireless Routers (FWR) to provide radio coverage to otherwise shadowed areas. Highest spectrum capacity and lowest possible transmit power as main t a r p t s will be e reached by using low power (1 W) pic0 base stations using a wireless or mobile broadband air interface at Access Points (AP) to the core network and at FWRs to trade the high capacity available at APs against radio coverage range. The so-called Wireless Media System (WMS) will provide broadband access to terminals with medium velocity of movement and is embedded into a cellular radio network to support a high velocity of terminals with medium transmission rate. The low power used at the base stations leads to a pico-cellular concept relying essentially on multihop communication across r u e d wireless bridges or routers and to some extent also on ad-hoc networking. The new concept to achieve broadband radio coverage in densely populated areas is described and fwst analysis results of some crucial elements are presented.
