Abstract

A wireless communication network comprises a plurality of wireless communication nodes, each wireless communication node comprising a first wireless access point and a second wireless access point coupled to the first wireless access point. The first wireless access point is configured in a first mode to wirelessly communicate with at least one wireless client and with a wireless access point of another wireless communication node. The second wireless access point is configured to wirelessly communicate with a wireless access point of a different other wireless communication node. Multiple wireless communication nodes according the present invention may be coupled together to form a wireless bridged network.
