Abstract

A wireless communication device (10) includes a radio frequency transceiver (22) adapted for burst transmission responsive to an enable signal in accordance with at least one communication protocol and an infrared transceiver (24) adapted for asynchronous data communication. The infrared transceiver (24) is responsive to the enable signal to suspend data communication. A controller (20) is coupled to each of the radio frequency transceiver (22) and the infrared transceiver (24), and the controller (20) is operable to generate the enable signal in accordance with the at least one communication protocol.

Claims

1. A wireless communication device comprising:

a controller for generating a control signal;

a first communication module coupled to the controller, the first communication module communicating a pulsed signal responsive to the control signal; and

a secondary communication module coupled to the controller,

the second communication module communicating a second signal, the second communication module responsive to the control signal to suspend an ongoing transmission of the second signal for a duration of the pulsed signal.

2. The wireless communication device of claim 1, wherein the first communication module comprises a radio frequency transceiver adapted for burst operation.

3. A portable communication device comprising:

a controller having a control signal output;

a first communication module coupled to the control signal output of the controller;

a second communication module coupled to the control signal output of the controller,

the first communication module providing a first signal having a signal duration in response to a control signal on the control signal output of the controller,

the second communication module interrupting an ongoing communication of a second signal during the communication of the first signal in response to the control signal on the control signal output of the controller.

4. The portable communication device of claim 3,

the secondary communication module resuming interrupted communications of the second signal after the signal duration of the first signal.

5. A method in a portable communication device, the method comprising:

communicating a first signal as a series of pulses separated by intervals of inactivity;

communicating a second signal only during the intervals of inactivity of the first signals.

6. The method of claim 5,

interrupting the communication of the second signal during the pulses of the first signal.

7. The method of claim 6,

after interrupting, resuming the communication of the second signal during the intervals of inactivity of the first signal.

8. The method of claim 6, controlling the communication of the first signal and the interruption of the second signals with a common control signal.

9. A method in a communication device, the method comprising:

communicating a first signal as a series of pulses separated by intervals of inactivity;

communicating a second signal;

interrupting the communication of the second signal during the pulses of the first signal;

resuming transmission of the second signal during the intervals of inactivity of the first signal.

10. The method of claim 9,

communicating the first signal in response to a control signal;

interrupting the communication of the second signal in response to a control signal.

11. The method of claim 10,

interrupting communication of the second signal in response to the same control signal in response to which the first signal is communicated.

12. The method of claim 9,

communicating the first signal as a series of pulses separated by intervals of inactivity includes transmitting the first signal.

13. A method in a wireless communications device, the method comprising:

communicating a pulsed signal having pulses separated by corresponding intervals of inactivity;

communicating a second signal at virtually the same time that the pulsed signal is communicating by communicating the second signal during the intervals of inactivity between pulses and interrupting communicating of the second signal during the pulses of the pulsed signal.

14. The method of claim 13,

communicating the pulsed signal in response to a control signal,

interrupting communication of the second signal in response to a control signal.

15. The method of claim 13, communicating the pulsed signal includes transmitting the pulsed signal.

16. A method in a communication device having a first communication module and a second communication module coupled to a controller, the method comprising:

communicating a first signal from the first communication module in response to a control signal from the controller;

interrupting communication of a second signal from the second communications module in response to the control signal;

resuming the communication of the second signal upon completion of the communication of the first signal.

17. The method of claim 16,

communicating the first signal for a first signal duration,

interrupting the communication of the second signal during the first signal duration,

resuming the communication of the second signal after the first signal duration.

18. The method of claim 16,

communicating the first signal as multiple bursts in response to a corresponding control signal, the multiple bursts each having a burst duration and separated by an interval between bursts,

interrupting the communication of the second signal during each burst duration,

resuming the communication of the second signal during the interval between bursts.

19. A method in a communication device, the method comprising:

receiving a pre-enable signal indicative that a signal will be communicated within a predetermined time period;

determining whether another signal can be communicated before the predetermined time period expires;

communicating the other signal only if the other signal may be communicated before the predetermined time period expires.

20. The method of claim 19,

determining whether the other signal can be communicated before the predetermined time period expires includes determining whether an ongoing communication of the other signal may be completed before the predetermined time period expires.

21. The method of claim 20,

completing communication of the other signal only if communication of the second signal may be completed before the predetermined time period expires.

22. The method of claim 20,

interrupting communication of the other signal if communication of the other signal cannot be completed before the predetermined time period expires.

23. A method in a communication device, the method comprising:

communicating a first signal having a known signal characteristic including intervals of relatively high energy separated by intervals substantially without energy;

communicating a second signal at virtually the same time that the first signal is communicated by

communicating the second signal only during the intervals substantially without energy.
