Abstract :
The transmission performance of a mobile/wireless broadband digital radio system, using the 60 GHz band, is evaluated for different antenna configurations in two indoor scenarios. It is shown that for the same equalization effort the maximum achievable carrier bit rate (CBR) strongly depends on the antenna configuration. A CBR of 40-50 Mbit/s in a medium size room and 20 Mbit/s in a large room using biconic horn antennas at the mobile terminal (MT) and at the base station transceiver (BST) is achievable, while this limit increases up to 100 Mbit/s when using two horn antennas located in the two narrower lateral walls of the room. Moreover, a simple method to estimate the maximum CBR based on the channel time dispersion is presented. Simulation results for several MT positions along the rooms are presented and discussed
