Reconfigureable arrays of wireless access points
A wireless communications network includes a reconfigurable array of access points for linking wireless devices in an infrastructure mode. One or more of the access points are mobile. The mobile access points in the network can be repositioned to change the geographic distribution of the bandwidth coverage provided by the wireless network. The mobile access points may be repositioned to redistribute available network bandwidth heterogeneously according to the demand for bandwidth in local areas and to meet quality of service standards.

5. The wireless network of claim 1 further comprising an overhead rail coupled to the at least one mobile access point and to the building, wherein the at least one mobile access point is configured to move between the plurality of geographic locations via the overhead rail.
6. The wireless network of claim 1 further comprising a floor vehicle coupled to the mobile access point, wherein the at least one mobile access point is configured to move between the plurality of geographic locations via the floor vehicle.
7. The wireless network of claim 1 further comprising a user wireless device in communication with the at least one mobile access device, wherein the at least one mobile access point is configured to move between the plurality of geographic locations with the user wireless device.
8. The wireless network of claim 7 wherein the user wireless device is a mobile RFID portal.
9. A wireless network housed within a structure having a plurality of geographic locations, comprising:
a grid of rails disposed in the plurality of geographic locations;
at least one mobile access point configured to travel between the plurality of geographic locations on the grid of rails; and
a network controller coupled to the at least one mobile access point, wherein the network controller configured to:
receive an indication of relative demand for access to the wireless network by users at the plurality of geographic locations,
evaluate the indication of relative demand for access to the wireless network, and
selectively vary a position of the mobile access point among the plurality of geographic locations based at least in part on the evaluation of the indication of relative demand for access to the wireless network.
10. The wireless network of claim 9 wherein the grid of rails comprises an electrified rail for supplying power to the mobile access point.
11. The wireless network of claim 9 wherein the mobile access point is powered by rechargeable batteries, and the wireless network further comprises a docking station for recharging the rechargeable batteries.
12. The wireless network of claim 9 , further comprising:
a mobile RFID portal having an RFID reader, wherein the at least one mobile access point is disposed on the mobile RFID portal by which the RFID reader communicates data over the wireless network.
13. A method of providing wireless communication network services to wireless device users in a structure, comprising:
receiving, via a network controller, an indication of relative demand for access to the wireless network by users at a plurality of geographic locations within the structure;
evaluating, via the network controller, the indication of relative demand for access to the wireless network; and
automatically moving, via the network controller, a mobile access point between the plurality of geographic locations to provide additional bandwidth for wireless devices that are within a range R of each respective geographic location based at least in part on the evaluation of the indication of relative demand for access to the wireless network.
14. The method of claim 13 wherein automatically moving comprises automatically moving the mobile access point from a first geographic location to a second geographic location according to a schedule.
15. The method of claim 13 wherein automatically moving comprises automatically moving the mobile access point from a first geographic location to a second geographic location to meet a quality of service requirement for wireless device users in the proximity of the second geographic location.
16. The method of claim 13 further comprising locating a wireless device within the communication network, and wherein automatically moving further comprises automatically moving the mobile access point from a first geographic location to a second geographic location to locate the wireless device.
17. The method of claim 13 wherein the wireless device is an RFID portal and wherein automatically moving comprises co-disposing the RFID portal and the mobile access point on a common vehicle.
18. A method for dynamically changing a bandwidth of a plurality of geographic locations within a structure serviced by a wireless communication network, comprising the steps of:
determining, via a network controller, a first increase in user demand to access the wireless communication network via a first access point disposed at a first geographic location; and
automatically moving, via the network controller, a first mobile access point within a range R of the first geographic location in response to the first increase in user demand.
19. The method of claim 18 , further comprising the steps of:
determining, via the network controller, a second increase in user demand to access the wireless communication network via a second access point disposed at a second geographic location; and
automatically moving, via the network controller, a second mobile access point within a range R of the second geographic location in response to the second increase in user demand.
