Abstract

In an apparatus having both a first communication module of a first communication type and a second communication module of a second communication type, initiating a reaction of the first module to an activity of the second module over a particular communication channel if the first module is about to perform an action at a particular carrier frequency for the purpose of entering a connected state with a device of the first communication type and the particular frequency overlaps the particular channel.

Claims

1. A method comprising:

initiating a reaction of a first communication device of a first communication type to an activity of a communication device of a second communication type over a particular communication channel if said first communication device is about to perform an action at a particular carrier frequency for the purpose of entering a connected state with a second communication device of said first communication type and said particular frequency overlaps said particular channel.

2. The method of claim 1, wherein said first communication type is Bluetooth®

core specifications v1.1 or v1.2.

3. The method of claim 1, wherein said action includes transmission of an inquiry message and said reaction includes canceling said transmission.

4. The method of claim 1, wherein said action includes transmission of an inquiry response and said reaction includes canceling said transmission.

5. The method of claim 1, wherein said action includes initiating a paging handshake with said second communication device of said first communication type and wherein said reaction includes canceling initiation of said paging handshake.

6. The method of claim 1, wherein said action includes setting an inquiry scan interval to a first duration and said reaction includes setting said inquiry scan interval to a second duration that is longer than said first duration.

7. The method of claim 1, wherein said action includes setting an inquiry scan window to a first duration and said reaction includes setting said inquiry scan window to a second duration that is longer than said first duration.

8. The method of claim 1, wherein said second communication type is 802.11g.

9. The method of claim 8, further comprising:

identifying that the type of said activity is reception of a 802.11g signal.

10. The method of claim 8, further comprising:

identifying that the type of said activity is reception of a high priority 802.11g signal.

11. The method of claim 8, further comprising:

identifying that the type of said activity is transmission of a 802.11g signal.

12. The method of claim 8, further comprising:

identifying that the type of said activity is transmission of a high priority 802.11g signal.

13. The method of claim 1, further comprising:

monitoring a hard-wired indication generated by said communication device of said second communication type; and

identifying said particular channel and identifying the type of said activity from said indication.

14. The method of claim 1, further comprising:

monitoring a software indication generated by said communication device of said second communication type; and

identifying said particular channel and identifying the type of said activity from said indication.

15. An article comprising a storage medium having stored thereon instructions that, when executed, result in:

initiating a reaction of a first Bluetooth core specifications v1.2 device to an activity of a 802.11g device over a particular 802.11g communication channel if said first Bluetooth device is about to perform an action at a particular Bluetooth carrier frequency for the purpose of entering a connected state with a second Bluetooth core specifications v1.2 device and said particular frequency overlaps said particular channel.

16. The article of claim 15, wherein said action includes transmission of an inquiry message and said reaction includes canceling said transmission.

17. The article of claim 15, wherein said action includes transmission of an inquiry response and said reaction includes canceling said transmission.

18. The article of claim 15, wherein said action includes initiating a paging handshake with said second Bluetooth device and wherein said reaction includes canceling initiation of said paging handshake.

19. The article of claim 15, wherein said action includes setting an inquiry scan interval to a first duration and said reaction includes setting said inquiry scan interval to a second duration that is longer than said first duration.

20. The article of claim 15, wherein said action includes setting an inquiry scan window to a first duration and said reaction includes setting said inquiry scan window to a second duration that is longer than said first duration.

21. An apparatus comprising:

a first communication module of a first communication type to perform an activity over a particular communication channel; and

a second communication module of a second communication type including a monopole antenna, a radio coupled to said antenna, and a processor,

wherein if said second communication module is about to perform an action at a particular carrier frequency for the purpose of entering a connected state with a device of said second communication type and said particular frequency overlaps said particular channel, said processor is to initiate a reaction of said second communication module to said activity.

22. The apparatus of claim 21, wherein said second communication type is Bluetooth®

core specifications v1.1 or v1.2.

23. The apparatus of claim 21, wherein said first communication type is 802.11g.

24. The apparatus of claim 21, wherein said action includes transmission of an inquiry message and said reaction includes canceling said transmission.

25. The apparatus of claim 21, wherein said action includes transmission of an inquiry response and said reaction includes canceling said transmission.

26. The apparatus of claim 21, wherein said action includes initiating a paging handshake with said device and wherein said reaction includes canceling initiation of said paging handshake.

27. The apparatus of claim 21, wherein said action includes setting an inquiry scan interval to a first duration and said reaction includes setting said inquiry scan interval to a second duration that is longer than said first duration.

28. The apparatus of claim 21, wherein said action includes setting an inquiry scan window to a first duration and said reaction includes setting said inquiry scan window to a second duration that is longer than said first duration.

29. The apparatus of claim 21, wherein said action includes setting an inquiry scan interval to a first duration and said reaction includes:

setting said inquiry scan interval to a second duration that is longer than said first duration.

30. The apparatus of claim 21, wherein said action includes setting an inquiry scan window to a first duration and said reaction includes:

setting said inquiry scan window to a second duration that is longer than said first duration.

31. The apparatus of claim 21, wherein said first communication module is to generate a hard-wired indication and said processor is to monitor said hard-wired indication and to identify therefrom said particular channel and the type of said activity.

32. The apparatus of claim 21, wherein said first communication module is to generate a software indication and said processor is to monitor said software indication and to identify therefrom said particular channel and the type of said activity.
