60 GHz Communications

Channel Measurements and Ray-Tracing Investigations and System Design

Broadband millimetre-wave transmission in the 60 GHz range is seen to be a promising method in order to meet the demanding requirements of future WPAN systems with regard to increasing data rates. The use of millimetre-wave techniques at 60 GHz offers many advantages for short-range systems compared to radio methods at lower frequencies. The main advantages of this frequency band are, on the one hand, the large (license-free) bandwidth which permits high data rates and in the short wavelength on the other which leads to small antenna dimensions even with multi-antenna systems. Furthermore, there is no interference with existing radio systems. In view of the high radio field attenuation and the high transmission losses of walls, the radio cells are small, but interferences by other millimetre-wave systems and neighbouring radio cells are small as well. One immediate application is, for example, wireless multimedia supply in aircraft cabins. In this respect, the properties of the broadband 60 GHz indoor channels are examined, system concept are developed and evaluated on real-time experimental system.
