A ROTATABLE ANTENNA APPARATUS AND METHOD OF CONFIGURING A TRANSMISSION BEAM FOR THE ROTATABLE ANTENNA APPARATUS

摘要

An antenna apparatus operates as a base station in a wireless network, with a method configuring a transmission beam within such antenna apparatus. The antenna apparatus has a rotatable antenna assembly employing selected transmission beam patterns, and a controller to rotate the antenna assembly altering its azimuth direction. During configuration mode, a sweep operation rotates the antenna assembly to selected azimuth directions. Quality metric determination circuitry determines, for each selected azimuth direction, a link quality metric for wireless terminals based on communication between the wireless terminals and the base station whilst the rotatable antenna assembly is at that selected azimuth direction. Transmission beam determination circuitry determines, from the link quality metrics determined for the wireless terminals at each selected azimuth direction, both a transmission beam pattern and an azimuth direction for subsequent communication with the wireless terminals. The antenna apparatus efficiently self-configures its transmission beam pattern and azimuth direction.
