ATTENUATION AND COUNTERMEASURES IN MILLIMETER-WAVE POINT-TO-MULTIPOINT NETWORKS

Whilst most propagation studies for line-of-sight links in the millime ter-wave range have in the past concentrated on point-to-point perform ance prediction, this study is specifically directed to point-to-multi point aspects, with a special interest in the possibility of using int elligent resource sharing techniques at the central node. Dual-polariz ation radar data, covering a 2-year period, are used to make predictio ns of attenuation and interference in the 20 to 50 GHz range for 1 to 20-km radius networks employing either adaptive gain, adaptive time di vision multiple access, or both techniques combined.
