Description

Method for antenna configuration selection of AP device, AP device and computer program product Technical Field The present disclosure relates to the field of communications, and more particularly, to a method of antenna configuration selection at an Access Point (AP) device, an AP device, and a computer program product. Background In a wireless communication network, an antenna is a component for transmitting or receiving electromagnetic wave signals, and is capable of mutually converting electric current in a transmission line and electromagnetic waves in a space. Antennas can be classified into omni-directional antennas and directional antennas according to directivity. To meet the need for wide coverage, an Access Point (AP) typically employs an omni-directional antenna that radiates uniformly at 360 ° in the horizontal plane, but such uniform radiation results in energy dispersion, low power density per unit angle, and is susceptible to ambient co-channel interference. With the development of wireless communication technology, the requirements of users on the service quality and coverage of wireless communication are higher, and only an omni-directional antenna has been difficult to meet the requirements of users. The directional antenna has the characteristics of strong directivity and high gain, the service range of wireless communication of the AP can be effectively enlarged, and the communication service quality of the station can be compensated by adopting the directional antenna. However, the coverage of both the omni-directional antenna and the directional antenna is fixed, and once the location of the station is changed, it may occur that the performance of the wireless communication system is affected due to weak or no signal received by the station. For this purpose, smart antenna technology is proposed. The intelligent antenna technology is characterized in that the beam direction is adaptively adjusted through array antenna hardware and an intelligent antenna algorithm which are composed of a plurality of antennas, useful signals are focused, interference signals are restrained, and therefore the capacity, coverage area and anti-interference capacity of wireless communication are improved, and the antenna is enabled to track and optimize signals intelligently. Some smart antenna algorithms include a default phase, a pre-training phase, and a training phase to form a dynamically optimized core flow. In the default phase, the antenna operates in the current configuration, maintaining basic communication functions and providing a reference for dynamic adjustment. If link quality anomalies are monitored, dynamic optimization is triggered. The dynamic optimization flow firstly pre-screens a candidate set of antenna combinations in an off-line or semi-off-line mode in a pre-training stage, and then searches an optimal beam forming scheme in the current environment by traversing the candidate antenna combinations and combining real-time feedback in the training stage. However, current smart antenna algorithms determine that the period of optimal antenna configuration is long, and at the time the antenna configuration is determined, the client device may have moved, resulting in the determined antenna configuration expiring and no longer being applicable. Accordingly, there is a need for further improvements to existing smart antenna algorithms.
