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.

Claims

1. A communication system comprising:

a first wireless network;

a mobile service station, the mobile service station comprising a plurality of network devices and a battery power supply;

the plurality of network devices together forming a second wireless network operating as a subnetwork in the first wireless network; and

at least one of the plurality of network devices participating on the first wireless network to provide access for others of the plurality of network devices to the first wireless network.

2. The communication system of claim 1 wherein one of the plurality of network devices comprising an access server.

3. The communication system of claim 2 wherein the access server participates as a slave device in the first wireless network pursuant to a first communication protocol and as a master device in the second wireless network pursuant to a second communication protocol.

4. The communication system of claim 3 wherein the access server resolves conflicts between the first and second communication protocols.

5. The communication system of claim 1 wherein the at least one of the plurality of network devices participates as a slave device in the first wireless network pursuant to a first communication protocol and as a master device in the second wireless network pursuant to a second communication protocol.

6. The communication system of claim 1 wherein one of the plurality of network devices other than the at least one of the plurality of network devices participates as a slave device in the first wireless network pursuant to a first communication protocol and as a slave device in the second wireless network pursuant to a second communication protocol.

7. A communication system comprising:

a wireless premises network;

a wireless peripheral subnetwork having a relatively shorter range than the wireless premises network;

a mobile network device capable of communicating with the wireless premises network and the wireless peripheral subnetwork; and

a mobile service station having a battery power supply, the mobile service station configured to receive the mobile network device in mounting relation therewith, thereby providing the mobile network device access to the battery power supply.

8. The communication system of claim 7 wherein the mobile network device participates on the peripheral subnetwork when the mobile network device is within the relatively shorter range of the peripheral subnetwork.

9. The communication system of claim 7 further comprising a peripheral device disposed on the mobile service station which participates in the peripheral subnetwork.

10. The communication system of claim 7 wherein the mobile network device participates as a slave device in the wireless premises network pursuant to a first communication protocol while participating as a master device in the peripheral subnetwork pursuant to a second communication protocol.

11. The communication system of claim 10 wherein the mobile network device resolves conflicts between the first and second communication protocols.

12. The communication system of claim 7 wherein the mobile network device enters a state of low power consumption when not communicating with either the wireless premises network or the peripheral subnetwork.

13. The communication system of claim 7, the wireless premises network having a first plurality of network devices and the peripheral subnetwork having a second plurality of network devices such that when within range of one of the second plurality of network devices, the mobile network device participates as a master device in the peripheral subnetwork and when within range of one of the first plurality of network devices, the mobile network device participates as a slave device in the wireless premises network.

14. The communication system of claim 7 further comprising:

a network device independent of the mobile network device;
