Abstract

A communication system including a battery powered mobile service station is used to provide transactional support within a premises. The mobile service station includes a plurality of network devices that operate on a second wireless network, where at least one of the plurality of network devices participates on a first wireless network. In one embodiment, a network device participates as a slave device on the first wireless network and participates as a master device in the second wireless network. In another embodiment, a mobile service station includes a mobile network device that simultaneously operates over a wireless premises network and a wireless peripheral sub-network having a relatively shorter range than the wireless premises network. One or more peripheral devices communicate with the mobile network device in the peripheral sub-network. The mobile service station includes a battery power supply and may further include a peripheral device coupled to the battery. The mobile network device mounts to the service station and has access to the battery. The service station houses a number of peripheral devices which are used in merchandising operations to conclude customer purchase transactions. The peripheral devices may include a printer, a magnetic card reader and a cash drawer, and may wirelessly communicate with the mobile network device.

Claims

1. A communication system comprising:

a first wireless network;

a mobile service vehicle, the mobile service vehicle having a power supply associated therewith;

a plurality of network devices wirelessly communicating with one another to form a second wireless network operating as a subnetwork in the first wireless network; and

at least a first network device of the plurality of network devices being adapted to receive power from the power supply associated with the mobile service vehicle, and participating on the first wireless network to provide access for a second network device of the plurality of network devices to the first wireless network.

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

3. The communication system of claim 2 wherein the access server is adapted to participate 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 at least the first network device 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 first network device 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 comprising a plurality of network devices, each 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 vehicle having a power supply associated with the vehicle, the mobile service vehicle configured to receive the mobile network device in mounting relation therewith, thereby providing the mobile network device access to the power supply associated with the vehicle.

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

9. The communication system of claim 7 further comprising a peripheral device disposed on the mobile service vehicle which is adapted to participate in the wireless 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 wireless 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.
