Beamforming is a method of intensifying radio frequency energy at desired places to improve the signal to noise ratio. Beamforming may increase system capacity and performance, suppress interference and noise, and it may save power consumption However, using a dynamic beam steering scheme has a key problem when processing a handover between Access Points (APs). In this paper, the authors propose a Dynamic Beamforming Handover (DBH) scheme using the joint information of beam pattern and topology. Each access point pre-configures the neighbor list information and checks what candidate APs are available during handoff.
