ABSTRACT:
A high reliability access point for RF communications in a wireless local area network. The high reliability access point includes a central processing unit (CPU) for handling high level protocol functions and for interfacing with the infrastructure of the local area network. The high reliability access point also includes at least two wireless adapters. Each wireless adapter includes a radio, a media access control (MAC) processor for handling low level protocol functions, and at least one antenna. The multiple wireless adapters allow the access point to perform self monitoring, reduce the effects of multipath interference, reduce some occurrences of collisions at the access point and provide infrastructure backup in the event of an infrastructure failure. The access points also allow for wireless network infrastructure communication for connection of one or more remote access points to the infrastructure. A backup power supply for the access point is also shown.
