Abstract
A method for supporting wireless roaming among coverage areas of a plurality of access points may comprise detecting, by a first access point of the plurality of access points, signal strength of signals from a client device that is wirelessly connected to the first access point; comparing the signal strength with a threshold, and if the signal strength is less than the threshold, disconnecting, by the first access point, the client device from the first access point; transmitting, by the first access point, a signal indicating the disconnection of the client device to an access controller; updating, by the access controller, connection status information to indicate the disconnection of the client device from the first access point; transmitting, by the access controller, the connection status information of the client device to the plurality of access points; and connecting the client device with a second access point of the plurality of access points.
