Abstract

A wireless communication device (10) includes a radio frequency transceiver (22) adapted for burst transmission responsive to a control signal in accordance with at least one communication protocol and an infrared transceiver (24) adapted for asynchronous data communication in coordination. The infrared transceiver (24) is responsive to the control signal to suspend an ongoing data communication for the duration of the burst transmission and to resume the data communication following the burst transmission. A controller (20) is coupled to each of the radio frequency communication module (22) and the infrared communication module (24), and the controller (20) is operable to generate the control 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 primary communication module, coupled to the controller, adapted to provide a pulsed communication signal responsive to the control signal; and

a secondary communication module, coupled to the controller, arranged to transmit a data communication signal and being responsive to the control signal to suspend an ongoing transmission of the data communication signal for a duration of the pulsed, communication signal.

2. The wireless communication device of claim 1, further comprising a memory, coupled to the controller, arranged to retain a portion of the data communication signal for the duration of the pulsed communication signal.

3. The wireless communication device of claim 2, wherein the memory comprises one of a hardware buffer and a software buffer.

4. The wireless communication device of claim 1, wherein the wireless communication device comprises one of a cellular radiotelephone and a pager.

5. The wireless communication device of claim 1, wherein the secondary communication module comprises one of an infrared transceiver and a low-power radio frequency transceiver.

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

7. The wireless communication device of claim 1, wherein the control signal comprises at least one of a pre-enable signal and an enable signal.

8. The wireless communication device of claim 1, wherein the pulsed communication signal comprises a time-division multiplexed radio frequency communication signal.

9. A wireless communication device comprising:

a radio frequency transceiver adapted for burst transmission responsive to a control signal in accordance with at least one communication protocol;

an infrared transceiver adapted for asynchronous data communication, the infrared transceiver being responsive to the control signal to suspend an ongoing data communication; and

a controller coupled to each of the radio frequency transceiver and the infrared transceiver, the controller being operable to generate the control signal in accordance with the at least one communication protocol.

10. The wireless communication device of claim 9, further comprising a memory arranged to store data while the ongoing data communication is suspended.

11. The wireless communication device of claim 10, wherein the memory comprises one of a hardware buffer and a software buffer associated with at least one of the infrared transceiver and the controller.

12. The wireless communication device of claim 9, wherein the wireless communication device comprises one of a cellular radiotelephone and a pager.

13. The wireless communication device of claim 9, wherein the control signal comprises one of a pre-enable signal and an enable signal.

14. A method of controlling a communication device, the communication device comprising a primary transceiver for sending primary communication signals in accordance with a first communication protocol and a secondary transceiver for sending secondary communication signals in accordance with a second communication protocol, the method comprising the steps of:

initiating a communication of data words from the communication device to a recipient device using the secondary transceiver;

observing a control signal, the control signal indicating an activation of the primary transceiver;

responsive to the control signal, suspending the communication of data words;

storing data words that would have been transmitted while the communication is suspended; and

resuming the communication following a deactivation of the primary transceiver.

15. The method of claim 14, wherein the step of observing a control signal comprises observing at least one of a pre-enable signal and an enable signal.

16. The method of claim 14, wherein the step of suspending the communication comprises determining that an additional data word is available for communication before the primary transceiver is activated, and communicating the additional data word before the primary transceiver is activated.

17. The method of claim 14, wherein the step of resuming the communication comprises waiting a predetermined time period following deactivation of the primary transceiver.

18. The method of claim 14, wherein the step of resuming the communication comprises first communicating the stored data words.

19. A method in a wireless radio communication device, comprising:

transmitting a first radio signal from a first transmitter of the wireless radio communication device;

transmitting a second signal for an intermittent time period during the transmission of the first radio signal, the second signal transmitted from a second transmitter of the wireless radio communication device;

interrupting the transmission of the first radio signal during the transmission of the second signal and resuming transmission of the first radio signal upon completion of the transmission of the second signal.

20. The method of claim 19, buffering information of the first radio signal at least during the interruption of the transmission of the first radio signal.

21. The method of claim 19, interrupting the transmission of the first radio signal during the transmission of the second signal with a controller and resuming transmission of the first radio signal upon completion of the transmission of the second signal in response to signals with the controller.
