Bézier Curves Based Novel Calibration Technique of Beamformers in IEEE 802.11 WLAN Networks

IEEE 802.11 WLAN networks face challenges for end- to-end service performance concerning new mobility applications: real-time interactive communications, analytics and business intelligence.

In dense indoor deployments, co-channel interference is a major issue.

One of Radio Resource Management (RRM) techniques that is used to tackle this issue and maximize transmit opportunity is beamforming.

Bézier curves-based novel out-of-path beamforming calibration technique in IEEE 802.11 WLAN networks

Beamforming is a major building block of Radio Resource Management (RRM) in WLAN networks that helps mitigate the interference and maximize the transmission opportunity of Access Points (AP) toward Wireless Devices (WD).

In contrast to the related-work In-Path approaches, we propose a novel Out-Of-Path approach to beamforming calibration that is based on concepts from Computer Aided Graphical Design (CAGD) field and now-a-day network design best practices.

The enhancement that the presented solution adds to the beamforming operation time and results’ accuracy is investigated.
