Directed antennas in the Mobile Broadband System

摘要: The article investigates the usage of adaptive directed antennas for Mobile Broadband System (MBS). advantages and problems are considered. Solutions proposed evaluated with respect to cost, feasibility efficiency. MBS is a wireless cellular network operating at 60 GHz. It has been developed in European collaborative RACE II project R2057, addressing techniques technology (especially GaAs MMIC, i.e. millimetre-wave monolithic integrated circuits) as well system concepts. A major feature transparently transport ATM cells over air interface bit rates 34 Mbit/s per carrier.
