BACKUP CELL CONTROLLER
First Claim
1. A wireless local area network for data communications between a computer and at least one mobile unit, comprising:
- first and second cell controllers connected to said computer;
at least one rf port connected to a primary interface of said first cell controller and connected to a back-up interface of said second cell controller; and
a control program in said second cell controller monitoring data communications with said at least one rf port via said back-up interface, said program being arranged to cause said second cell controller to assume primary communications functions with said at least one rf port in the event primary communications functions of said first cell controller are inoperative for communication with said at least one rf port.

Abstract
A wireless local area network for data communications between a computer and mobile units is provided with at least two cell controllers connected to the computer and one or more rf ports each connected to a primary interface of one cell controller and to a backup interface of another cell controller. A control program in the cell controller monitors data communications between the other cell controller and the rf port by a backup interface. The program is arranged to cause the second cell controller to assume primary communications functions for the rf port in the event primary communications functions between a first cell controller and the rf port are inoperative.

6. A back-up cell controller for use in a wireless local area network for data communications between a computer and at least one mobile unit, comprising:
-
at least one interface for connection to an rf port; and a cell controller program monitoring data communications from an rf port connected to said interface, said program being arranged to cause said back-up cell controller to assume primary communications functions with said rf port in the event primary communications functions of another cell controller are inoperative for communication with said rf port. - View Dependent Claims (7, 8, 9)
