ADAPTIVE ANTENNA AND NETWORK INCORPORATING SAME

摘要

An adaptive antenna for hand over in a cellular communications network has elements (91, 92) which are capable of forming an optimised beam pattern in dependence upon weights of weighting devices (42, 47). A received signal from a mobile station (10) is ignored until the beam of the adaptive antenna has been appropriately optimised for the mobile station. It is only once the beam pattern has been appropriately formed that hand over to a new cell is effected. Thus, hand over is performed from one optimised beam in one cell to an optimised beam in another cell.
