8. The system of claim 7, wherein each client device responds to information read from a tag via the interface by obtaining from the server asset data associated with the tag.

9. The system of claim 1, wherein each of the plurality of client devices is a thin client device.

10. The system of claim 1, wherein each of the plurality of client devices is configured to communicate with other client devices within a range of the client device without accessing an access point.

11. The system of claim 1, wherein the client device transceivers are configured to transmit and receive text, audio, and video content.

12. The system of claim 1, wherein each of the client devices includes a cellular telephone.

13. The system of claim 1, wherein each of the client devices includes one of the plurality of tags.

14. The system of claim 1, further including a plurality of workstations coupled to the first network.

15. The system of claim 14, wherein one of the workstations includes an interface configured to read information from and write information to any of the plurality of tags.

16. The system of claim 14, wherein each of the workstations includes a local database including a portion of the data stored in the database coupled to the server.

17. The system of claim 1, further including a nurse call server coupled to the server, the nurse call server being configured to respond to input signals from an input device operated by a user by transmitting a request signal to the server, the server being configured to respond to the request signal by transmitting a signal to a particular client device.

18. The system of claim 1, further including a nurse call server coupled to the server, the nurse call server being configured to respond to input signals from an input device operated by a user by changing the status of an indicator.

19. The system of claim 1, further including a monitoring server coupled to the server, the monitoring server being configured to receive output data generated by a piece of equipment and to transmit the output data to the server.

20. The system of claim 1, wherein each of the client devices includes software configured to generate a plurality of screens on the display.

21. The system of claim 20, wherein the display is a touch sensitive display.
