Communication apparatus, method of transmission and antenna apparatus

摘要

Communications apparatus has a plurality of nodes each of which is capable of communicating with plural other nodes via point-to-point wireless transmission links between the nodes. At least one of the nodes has at least one antenna that is steerable in azimuth. The antenna is arranged to transmit an electromagnetic beam that has a beam width that is narrower in azimuth than in elevation. The beam width in azimuth is less than 9° and the beam width in elevation is less than about 15°.
