Embodiment Construction
[0016]FIG. 1 is a functional block diagram of an RF data communication system. In one embodiment of the present invention, the RF data communication system has a host computer 10, a network controller 14 and bridges 22 and 24 attached to a data communication link 16. Also attached to the data communication link 16 is a gateway 20 which acts as the root node for the spanning tree of the RF data network of the present invention. A bridge 42 is attached to the gateway 20 through a hard-wired communication link and bridges 40 and 44 are logically attached to gateway 20 by two independent RF links. Additional bridges 46, 48, 50 and 52 are also connected to the RF Network and are shown in the FIG. 1. Note that, although shown separate from the host computer 10, the gateway 20 (the spanning tree root node) may be part of host computer 10.
[0017]The FIG. 1 further shows RF terminals 100 and 102 attached to bridge 22 via RF links and RF terminal 104 attached to bridge 24 via an RF link. Also,...
