Modelling of Propagation in Outdoor Microcells at 62.4GHz

Results of Line-of-Sight (LOS) and Non Line-of-Sight (NLOS) mobile radio propagation experiments made to characterise 62 GHz sub-urban microcell channels employing omnidirectional antennas are presented. Experimental results are compared with theoretical predictions obtained from an exhaustive ray tracing algorithm. NLOS results show a sharp drop in the mean signal level when the direct component is blocked. The model is found not to be able to predict the signal with accuracy in the shadow region, where reflections do have a major influence, and are responsible for any coverage in there.
