The embodiment of the invention provides an antenna array unit selection method and device, which relate to the technical field of communication. The method, which is applied to a server, comprises steps: the location of a wireless client in a service range of a wireless access device with an intelligent antenna is acquired; a wireless client in a target area boundary is determined as a target client, wherein the target area is the area determined by the acquired location; according to the location of the target client, a radiation included angle for providing signals to the service range by the wireless access device is calculated, wherein the radiation included angle is the included angle formed by the boundary of a radiation pattern of the signals radiated by the intelligent antenna ofthe wireless access device; and the radiation included angle is sent to the wireless access device to enable the wireless access device to select an antenna array unit for providing service for the wireless client in the service range in the intelligent antenna according to the radiation included angle. The cost and the use power consumption of the wireless access device are reduced.
Description
Technical field [0001] This application relates to the field of communication technology, and in particular to an antenna element selection method and device. Background technique [0002] Smart antennas have multiple antenna elements. When using a wireless access device with a smart antenna to provide services to wireless clients within the service range, the wireless access device needs to select an antenna element from the smart antenna to receive the message sent by the wireless client or to the wireless client. The client sends a message. [0003] In the prior art, a wireless access device generally selects an antenna element from a smart antenna through a built-in dedicated CPLD (Complex Programmable Logic Device) chip according to a dedicated antenna element selection algorithm. Although the above method can be used to select the antenna element, the cost of the wireless access device is greatly increased due to the need to build the CPLD chip and supporting circuits in th...
