Abstract

A portable device comprising a base station emulator programmable to emit a signal and selectively page a wireless terminal that tunes to the signal to register, wherein the paging signal reveals the location of the wireless terminal. A method of locating an active wireless terminal inside an area. The method comprises transmitting an overhead signal that is dominant inside the area, receiving an identification signal from the wireless terminal and selectively paging the identified wireless terminal to reveal its location inside the area.

Claims (23)

1. A wireless terminal locator, comprising:

a transmitter for transmitting a dominant overhead signal inside an area in which external overhead signals have been attenuated;

a receiver for receiving a wireless terminal identification inside the area; and

a processor operable for instructing the transmitter to selectively page an identified wireless terminal to cause the identified wireless terminal to emit an audible ring and to reveal a location of the identified wireless terminal inside the area.

2. The wireless terminal locator of claim 1 , wherein the locator is handheld.

3. The wireless terminal locator of claim 1 , wherein the locator is portable.

4. The wireless terminal locator of claim 1 , wherein the locator is wall mounted.

5. The wireless terminal locator of claim 1 , further comprising a data storage device.

6. The wireless terminal locator of claim 1 , further comprising a display.

7. The wireless terminal locator of claim 1 , further comprising an operator interface for real time control.

8. A wireless terminal locator, comprising:

means for transmitting a dominant overhead signal inside an area in which external overhead signals have been attenuated;

means for receiving a wireless terminal identification inside the area; and

processor means for instructing the transmitting means to selectively page an identified wireless terminal to cause the identified wireless terminal to emit an audible ring and thereby reveal a location of the wireless terminal inside the area.

9. A method of locating a wireless terminal inside an area in which external overhead signals have been attenuated, the method comprising:

transmitting an overhead signal that is dominate inside the area;

receiving an identification from the wireless terminal; and

selectively paging the identified wireless terminal to cause the identified wireless terminal to emit all audible ring and audibly reveal a location of the wireless terminal inside the area.

10. The method of claim 9 , further comprising:

queuing the identified wireless terminal before paging.

11. The method of claim 9 , further comprising comparing the identification information with a predetermined list of wireless terminal identifications and paging the wireless terminal when it is not included in the predetermined list.

12. The method of claim 9 , wherein selectively paging comprises paging the wireless terminal only when operator input to page the wireless terminal is provided.

13. The method of claim 9 , wherein selectively paging comprises paging the wireless terminal unless operator input not to page the wireless terminal is provided.
