Enhanced mobility and address resolution in a wireless premises based network
First Claim
1. A roaming network device comprising:
- a radio unit providing radio communication;
the roaming network device, when in proximity to second and third roaming network devices, operating to establish a multiple direct link localized radio network with the second and third network devices wherein the radio unit has a direct radio communication link with the second network device and a direct radio communication link with the third network device and wherein the roaming network device and the second and third roaming network devices together comprise a roaming workgroup while the multiple direct link localized radio network is established and while the roaming network device and the second and third roaming network devices remain in proximity to each other.

Abstract
A mobile customer service station operating within a wireless multi-hop communication network includes a console on a wheeled chassis. The console carries and houses a number of components which are used in merchandising operations to conclude customer purchase transactions. The items supported externally on the console are a printer for printing purchase receipts, customer credit charge agreements and records of transactions, and a magnetic card reader for reading information from a magnetic stripe of a customer'"'"'s credit card. In one embodiment, the operation of the printer, credit card reader and the cash drawer is controlled by a multi-function control unit located within an enclosure of the console. The control unit is electrically powered by a self-contained power source which is preferably a deep cycle rechargeable battery. The console also houses a transceiver unit which under the control of the control unit is capable of interactive communication with a premises network. In another embodiment, the mobile service station comprises an access device which participates with a variety of peripherals at the station in a lower power communication LAN, while providing higher power communication to other network devices via a premises network with routing via a wireless spanning tree configuration.
