Abstract

A wireless network having a base station adapted for wireless communications, a wireless bar code scanner and a network ID label having a bar code symbol printed thereon. The bar code symbol includes encoded information pertaining to the base station. A wireless bar code scanner is adapted to scan and decode the network ID label. The wireless bar code scanner initiates a communications link with the base station utilizing information from the decoded network ID label. The wireless bar code scanner includes a light source for illuminating a printed bar code symbol, an electro-optical element for imaging the printed bar code symbol, a decoder for decoding the imaged printed bar code symbol into an alphanumeric string, and an input/output device for conducting wireless communications with the base station.

Claims

1. A wireless network comprising:

a base station adapted for wireless communications;

a wireless scanner for communicating with said base station, said wireless scanner adapted to scan and decode a printed bar code label; and

a network ID label having a bar code symbol printed thereon, said bar code symbol including coded information pertaining to said base station;

wherein a wireless communications link is initiated between said base station and said wireless scanner when said wireless scanner scans and decodes said network ID label.

2. The wireless network of claim 1 wherein said base station comprises:

a radio device for communicating with wireless devices in the wireless network.

3. The wireless network of claim 1 wherein said base station comprises:

a host computer having a keyboard connected to the host computer through a cable; and

a wedge, connected to the cable between the keyboard and said host computer, said wedge including a radio device for communicating with wireless devices in the wireless network.

4. The wireless network of claim 1 further comprising:

a switch disposed on said wireless scanner, said switch being moveable between a first position for scanning and decoding said printed bar code label to initiate a communications link with said base station, and a second position for scanning and decoding said printed bar code symbol and transmitting said decoded information across an established wireless communications link.

5. The wireless network of claim 1 further comprising:

a decoder disposed in said wireless scanner, said decoder adapted to decode standard bar code symbologies and further adapted to initiate a communications link when a series of at least one special character is decoded;

wherein said bar code symbol of said network ID label includes said series of at least one special character.

6. The wireless network of claim 1 wherein said wireless scanner comprises:

a decoder for decoding said printed bar code label into a decoded alphanumeric string, said decoder comprising algorithms for decoding a first set of bar code symbologies and a second set of bar code symbologies;

wherein said network ID label is encoded utilizing a symbology from said second set of bar code symbologies.

7. The wireless network of claim 6 further comprising:

an I/O device adapted to conduct wireless communications, and

an interface controller for controlling the communications of said I/O device.

8. The wireless network of claim 7 wherein said decoder transmits said decoded alphanumeric string decoded in accordance with said first set of bar code symbologies to said I/O device where said decoded information is transmitted to said base station.

9. The wireless network of claim 8 wherein said decoder transmits said decoded alphanumeric string decoded in accordance with said second set of bar code symbologies to said interface controller to initiate said wireless communications link with said base station.

10. The wireless network of claim 2 wherein said wedge further comprises:

a processor for controlling the operation of the wedge;

a memory for storing program instructions for controlling the CPU, and for providing temporary data storage;

an I/O device for communicating with the host computer; and

a radio device for controlling RF communications between the wedge and said wireless scanner of the wireless network.

11. The wireless network of claim 6 wherein said network ID label, encoded in accordance with a symbology from said first set of bar code symbologies, cannot be decoded by said algorithms for decoding said second set of bar code symbologies.

12. The wireless network of claim 1 wherein said network ID label is disposed within RF range of said base station.

13. A wireless bar code scanner for wireless communications with a base station comprising:

a light source for illuminating a printed bar code symbol;

an electro-optical element for imaging said printed bar code symbol;

a decoder for decoding said imaged printed bar code symbol into an alphanumeric string;

an input/output device for conducting wireless communications with said base station;

wherein said wireless bar code scanner initiates a wireless communications link with said base station when said wireless scanner scans and decodes a printed bar code symbol having communications information corresponding to said base station.

14. The wireless bar code scanner of claim 13, wherein said decoder is adapted to recognize a printed bar code symbol having communications information encoded therein.

15. The wireless bar code scanner of claim 13 further comprising:

an interface controller for controlling wireless communications of the input/output device; and

a switch being movable between a first position connecting said decoder to said interface controller, and a second position connecting said decoder to said input/output device;

wherein, when said switch is in said first position, said decoder sends said decoded alphanumeric string to said interface controller to initiate a wireless communications link in accordance with information in said alphanumeric string; and

wherein, when said switch is in said second position, said decoder sends said decoded alphanumeric string to said input/output device to be sent to said base station over a wireless communications link.

16. A method, to be performed by a wireless bar code scanner, for wireless association between said wireless bar code scanner and a base station having a network ID label, comprising the steps of:

scanning said network ID label with said wireless bar code scanner, thereby obtaining communications information for initiating a wireless communications link with said base station; and

initiating a communications link between said wireless bar code scanner and said base station in accordance with said communications information.

17. The method of claim 16 wherein said step of scanning further comprises:

decoding said scanned network ID label with a decoder in said wireless bar code scanner, said decoder comprising algorithms for recognizing and decoding said network ID label.

18. The method of claim 16 wherein said step of initiating a communications link further comprises the step of:

listening on a control channel for a beacon from said base station.

19. The method of claim 18 wherein said step of initiating a communications link further comprises the step of:

transmitting an attach request to said base station after said beacon is detected in said step of listening.

20. The method of claim 19 further comprising the step of:

listening on said control channel for a response to said attach request from said base station.
