Multiple wireless local area networks occupying overlapping physical spaces
First Claim
1. A method for operating an RF port having a radio module, a digital processor, random access memory and read-only memory, comprising storing a bootloader program in said read-only memory, operating said digital processor to download instructions from a computer to said random access memory using said bootloader program and operating said RF port under said downloaded instructions to send and receive messages over at least two wireless local area subnetworks occupying common physical space using said radio module.

Abstract
A wireless local area network is provided with simplified RF ports which are configured to provide lower level media access control functions. Higher level media access control functions are provided in a cell controller, which may service one or more RF ports that are capable operating with at least two wireless local area subnetworks occupying common physical space. Mobile units can also be configured with the higher level media access control functions being performed in a host processor.
