Abstract
A method, an apparatus, and code in a carrier medium to operate in a first access point of a wireless network in communication with at least one associated client station. The method includes wirelessly broadcasting a management frame including an indication that the first access point will stop being active, such that each associated client station can wirelessly roam to a second access point prior to the first access point ceasing being active. One embodiment further includes reducing the transmit power of wireless communication used to wirelessly transmit information to the associated client stations, such that each associated client station can eventually wirelessly roam to the second access point.
