Assessment of Frequencies for Prometheus and Drive - The 60 GHz Mobile Radio Channel.

Kurzfassung

Several possible frequency bands are discussed for application in PROMETHEUS and DRIVE short- and medium-range communications. This paper considers the following frequencies: 900 MHz, 2.5 GHz, 6 GHz, 60 GHz. The aspects transmit power, transmission range, frequency reuse, bandwidth efficiency, influence of precipitation, attenuation due to obstacles, antennas and multipath fading will be discussed. Within the European PROMETHEUS research program the DLR investigates the 60 GHz link and is developping a channel model. A draft multipath propagation model is presented and compared with measurements. The probability density function of the received power shows a Rice/Rayleigh-Lognormal distribution. Simulations with measured channel data results in packet error rates in the order of 10-4 - 10-1 depending on the vehicles distance and the environment.
