Abstract

A method and apparatus is disclosed for providing a range of location dependent information and services to users of wireless devices coupled to the multi-point wireless access network of the current invention.

In an embodiment of the invention a multi-point wireless access network for servicing wireless devices is provided. The multi-point wireless access network includes: wireless access devices, an inventory map and a server. The wireless access points are arrayed in a coordinate system with a known relative relationship to one another. Each of the wireless access points provides communication capabilities for corresponding proximate ones of the wireless devices. The inventory map correlates selected ones of the wireless access points with corresponding inventory located proximate to each of the selected ones of the wireless access points. The server couples to the wireless access points and to the inventory map, and the server correlates each access to the multi-point wireless access network from a corresponding wireless device with the corresponding inventory from the inventory map to provide at least one of location dependant information and location dependant services to the corresponding wireless device.

Claims

1. A wireless access network (WAN) for servicing wireless devices, and the WAN comprising:

wireless access points (WAP) each having locations expressed in a coordinate system; and

each of the WAP configured to establish communications with proximate ones of the wireless devices; and

a server coupled to the WAP and the server configured to maintain access records correlating times of access by each wireless device with associated WAPs providing said access, and the server further configured to deliver to each wireless device, via a proximate WAP, a map including an overlay of a prior path of the wireless device through the WAN and the prior path determined by sorting the access records for each wireless device by a time of access to a corresponding WAP and generating the prior path as a sequence of vectors with coordinates corresponding with the locations of each successive WAP in the sorted access records.

2. The server of claim 1, further configured to convert the prior path for at least one of visual, textual or audible presentment on the wireless device.

3. The WAN of claim 1, further comprising:

inventory records correlating inventory items with an associated location in the coordinate system; and

the server further configured to deliver to the wireless device, via the proximate WAP, a destination path of the corresponding wireless access device to a corresponding item of inventory based on the location of the proximate WAP and the location of the corresponding item of inventory in the associated inventory record.

4. The server of claim 1, further configured to deliver the destination path to the wireless device responsive to at least one of a request from the wireless device for an item of inventory and a selection by the server of an item of inventory proximate to the proximate WAP as indicated by the access and inventory records.

5. A method for providing a multi-point wireless access network (WAN) to wireless devices, comprising:

providing wireless access points (WAP) each having locations identified in a coordinate system;

maintaining access records correlating times of access by each wireless device with associated WAPs providing said access; and

delivering to each wireless device, via a proximate WAP, a map including an overlay of a prior path of the wireless device through the WAN and the prior path determined by sorting the access records for each wireless device by a time of access to a corresponding WAP and generating the prior path as a sequence of vectors with coordinates corresponding with the locations of each successive WAP in the sorted access records.

6. The method of claim 5, wherein the delivering act further comprises:

converting the prior path for at least one of visual, textual or audible presentment on the wireless device.

7. The method of claim 5, further comprising:

maintaining inventory records correlating inventory items with an associated location in the coordinate system; and

delivering to the wireless device a destination path of the corresponding wireless access device to the corresponding item of inventory based on the location of the wireless device in the associated access record and the location of the corresponding item of inventory in the associated inventory record.

8. The method of claim 5, wherein the second delivering act further comprises:

delivering the destination path to the wireless device responsive to at least one of the acts of;

receiving a request from the wireless device for an item of inventory; and

selecting an item of inventory proximate to the proximate WAP as indicated by the access and inventory records.
