Patent attributes
The present disclosure discloses a method and a network device for efficient mobile client device roaming in a wireless local area network with multiple access points. Specifically, a network device determines a first received signal strength value for a first set of signals transmitted between a client device and a first access point during a first time period; and, determines a second received signal strength value for a second set of signals transmitted between a client device and the access point during a second time period. Based on the first and the second signal strength values, the network device computes a change in signal strength value corresponding to wireless communication between the client device and the first access point. Based on the change in signal strength value, the network device selects the access point from a plurality of access points for providing network access to the client device.
