Abstract
In a data processing system network, apparatus and method are disclosed for coupling two local area networks by means of a wireless link. Typically, two local area network (LAN) systems are coupled by a bridge device, the bridge device receiving signal groups from each LAN system and selectively forwarding the signal groups to the target LAN system. In the presence of the overlapping (or simultaneous) transmission of signal groups applied to the target LAN system, these signal groups must be reapplied to the target LAN system until a non-overlapping transmission is obtained. In the present invention, when the LAN systems are coupled by a wireless (radiation) link, an interface unit is coupled between each wireless transmitter/detector unit and the associated LAN system. Each interface unit includes a bridge device that provides the system response to the overlapping signal groups.
