Abstract

A wireless terminal is disclosed that functions as both a telecommunications device and as a wireless test tool. Illustratively, the terminal comprises a first electro-acoustic transducer for converting a first acoustic signal into an outgoing signal; a wireless transmitter capable of transmitting the outgoing signal to a remote base station; a wireless receiver capable of receiving a plurality of incoming signals from the base station; a second electro-acoustic transducer for converting one of the plurality of incoming signals into a second acoustic signal; a visual display; and a terminal processor for determining a power level for each of the plurality of incoming signals and for contemporaneously displaying an indicium of the power level for each of the plurality of incoming signals onto the visual display.

Claims

1. A wireless terminal comprising:

a first electro-acoustic transducer for converting a first acoustic signal into an outgoing signal;

a wireless transmitter capable of transmitting said outgoing signal to a remote base station;

a wireless receiver for receiving a plurality of incoming signals from said base station;

a second electro-acoustic transducer for converting one of said plurality of incoming signals into a second acoustic signal;

a visual display; and

a terminal processor for determining a measure of signal strength for each of said plurality of incoming signals and for contemporaneously displaying an indicium of said measure of signal strength for each of said plurality of incoming signals onto said visual display.

2. The wireless terminal of claim 1 wherein each of said plurality of incoming signals occupies one of a plurality of frequency-disparate communications channels.

3. The wireless terminal of claim 2 wherein said terminal processor contemporaneously displays on said display an indicium of which of said plurality of frequency-disparate communications channels is occupied by one of said plurality of incoming signals.

4. The wireless terminal of claim 1 wherein each of said plurality of incoming signals occupies one of a plurality of temporally-disparate communications channels.

5. The wireless terminal of claim 4 wherein said terminal processor contemporaneously displays on said display an indicium of which of said plurality of temporally-disparate communications channels is occupied by one of said plurality of incoming signals.

6. A wireless terminal comprising:

a first electro-acoustic transducer for converting a first acoustic signal into an outgoing signal;

a wireless transmitter for transmitting said outgoing signal to a remote base station;

a wireless receiver for receiving a plurality of incoming signals from said base station;

a second electro-acoustic transducer for converting one of said plurality of incoming signals into a second acoustic signal;

a visual display; and

a terminal processor for determining a bit error rate for each of said plurality of incoming signals and for contemporaneously displaying an indicium of said bit error rate for each of said plurality of incoming signals onto said visual display.

7. The wireless terminal of claim 6 wherein each of said plurality of incoming signals occupies one of a plurality of frequency-disparate communications channels.

8. The wireless terminal of claim 7 wherein said terminal processor contemporaneously displays on said display an indicium of which of said plurality of frequency-disparate communications channels is occupied by one of said plurality of incoming signals.

9. The wireless terminal of claim 6 wherein each of said plurality of incoming signals occupies one of a plurality of temporally-disparate communications channels.

10. The wireless terminal of claim 9 wherein said terminal processor contemporaneously displays on said display an indicium of which of said plurality of temporally-disparate communications channels is occupied by one of said plurality of incoming signals.

11. A method of operating a wireless terminal comprising:

converting a first acoustic signal into an outgoing signal with a first electro-acoustic transducer;

transmitting said outgoing signal to a remote base station with a wireless transmitter;

receiving a plurality of incoming signals with a wireless receiver;

converting one of said plurality of incoming signals into a second acoustic signal with a second electro-acoustic transducer;

determining a measure of signal strength for each of said plurality of incoming signals with a terminal processor; and

contemporaneously displaying on a visual display an indicium of said measure of signal strength for each of said plurality of incoming signals.

12. The method of claim 11 wherein each of said plurality of incoming signals occupies one of a plurality of frequency-disparate communications channels.

13. The method of claim 12 further comprising contemporaneously displaying on said display an indicium of which of said plurality of frequency-disparate communications channels is occupied by one of said plurality of incoming signals.

14. The method of claim 11 wherein each of said plurality of incoming signals occupies one of a plurality of temporally-disparate communications channels.

15. The method of claim 14 further comprising contemporaneously displaying on said display an indicium of which of said plurality of temporally-disparate communications channels is occupied by one of said plurality of incoming signals.

16. A method of operating a wireless terminal comprising:

converting a first acoustic signal into an outgoing signal with a first electro-acoustic transducer;

transmitting said outgoing signal to a remote base station with a wireless transmitter;

receiving a plurality of incoming signals with a wireless receiver;

converting one of said plurality of incoming signals into a second acoustic signal with a second electro-acoustic transducer;

determining a bit error rate for each of said plurality of incoming signals with a terminal processor; and

contemporaneously displaying on a visual display an indicium of said bit error rate for each of said plurality of incoming signals.

17. The method of claim 16 wherein each of said plurality of incoming signals occupies one of a plurality of frequency-disparate communications channels.

18. The method of claim 17 further comprising contemporaneously displaying on said display an indicium of which of said plurality of frequency-disparate communications channels is occupied by one of said plurality of incoming signals.

19. The method of claim 16 wherein each of said plurality of incoming signals occupies one of a plurality of temporally-disparate communications channels.

20. The method of claim 19 further comprising contemporaneously displaying on said display an indicium of which of said plurality of temporally-disparate communications channels is occupied by one of said plurality of incoming signals.
