Abstract

A public wireless data communication system is obtained by combining pay telephone and wireless data communication technologies. The system may be used to connect a wireless user access device to the Internet and/or other wide area or local area communications networks. A pay telephone includes a local loop connected to a public switched telephone network (PSTN). The local loop may be multiplexed to provide simultaneous wireless data communication and telephone call services. In one implementation, data communications equipment (e.g., an xDSL router/modem) and a wireless access point (e.g., an IEEE 802.11 access point) are connected to the pay telephone'"'"'s local loop to provide access to the Internet through an Internet service provider. Increased wireless data communication speed and bandwidth are achieved without requiring allocation of additional scarce, government-controlled spectrum.

Claims

1. A communications system comprising:

(a) a pay telephone connection to a public switched telephone network (PSTN);

(b) data communications equipment connected to the pay telephone connection, in which the data communications equipment is configured to provide data communication via the pstn; and

(c) a wireless access point connected to the data communications equipment, in which the wireless access point is configured to provide wireless communication that enables a wireless user access device to communicate data via the pay telephone pstn connection;

2. The communications system of claim 1, further comprising pay telephone equipment that is configured to enable a circuit switched telephone call to be placed simultaneous to data communication with the wireless user access device.

3. The communications system of claim 2, further comprising a splitter connected to the pay telephone PSTN connection, the splitter providing PSTN connections to both the pay telephone equipment and the data communications equipment.

4. The communications system of claim 2, in which the pay telephone equipment is connected to the pay telephone PSTN connection.

5. The communications system of claim 1, in which the pay telephone equipment is connected to the data communications equipment and communicates with the PSTN via the data communications equipment.

6. The communications system of claim 5, further comprising a splitter integrated with the data communications equipment and connected to the pay telephone PSTN connection to provide PSTN connections to both pay telephone equipment and the data communications equipment.

7. The communications system of claim 1, further comprising a filter connected to the pay telephone PSTN connection and configured to provide a PSTN connection with suppressed interference.

8. The communications system of claim 1, in which the wireless access point is further configured to enable the wireless user access device to connect to a communications network via the pay telephone PSTN connection.

9. The communications system of claim 8, in which the communications network is the Internet.

10. The communications system of claim 8, in which the communications network is a private network.

11. The communications system of claim 1, in which the data communications equipment includes digital subscriber line (DSL)-based equipment.

12. The communications system of claim 1, in which the wireless access point includes equipment conforming to an IEEE 802.11 standard.

13. A kit for retrofitting a pay telephone to provide wireless data communication, comprising:

(a) data communications equipment configured to be connected to a public switched telephone network (PSTN) connection of the pay telephone and provide data communication via the PSTN; and

(b) a wireless access point configured to be connected to the data communications equipment, in which the wireless access point provides wireless communication for a wireless user access device to communicate data via the PSTN connection of the pay telephone.

14. The kit of claim 13, further comprising a splitter configured to be connected to the PSTN connection of the pay telephone to provide PSTN connections to both the pay telephone and the data communications equipment.

15. The kit of claim 13, in which the data communications equipment is further configured to be connected to the pay telephone to enable placement of telephone calls via the data communications equipment simultaneous to data communication with the wireless user access device.

16. The kit of claim 13, further comprising a filter configured to be connected to the PSTN connection of the pay telephone for suppression of interference.

17. The kit of claim 13, in which the wireless access point is further configured to enable the wireless user access device to connect to a communications network via the PSTN connection of the pay telephone.

18. The kit of claim 17, in which the communications network is the Internet.

19. The kit of claim 17, in which the communications network is a private network.

20. The kit of claim 13, in which the data communications equipment includes digital subscriber line (DSL)-based equipment.

21. The kit of claim 13, in which the wireless access point includes equipment conforming to an IEEE 802.11 standard.

22. A method of providing wireless data communication using a pay telephone connection to a public switched telephone network (PSTN), comprising:

(a) connecting data communications equipment to the PSTN connection of the pay telephone, in which the data communications equipment is configured to provide data communication via the PSTN; and

(b) connecting a wireless access point to the data communications equipment, in which the wireless access point is configured to provide wireless communication that enables a wireless user access device to communicate data via the PSTN connection of the pay telephone.

23. The method of claim 22, further comprising connecting the data communications equipment to the pay telephone to enable placement of telephone calls via the data communications equipment simultaneous to data communication with the wireless user access device.

24. The method of claim 22, further comprising connecting a splitter to the PSTN connection of the pay telephone to provide PSTN connections to both the pay telephone and the data communications equipment.

25. The method of claim 22, further comprising connecting a filter to the PSTN connection of the pay telephone to suppress interference.

26. The method of claim 22, in which the wireless access point is configured to enable the wireless user access device to connect to a computer network via the PSTN connection of the pay telephone.

27. The method of claim 22, in which the data communications equipment includes digital subscriber line (DSL)-based equipment.

28. The method of claim 22, in which the wireless access point includes equipment conforming to an IEEE 802.11 standard.
