Abstract

A method for data transmission over first and second media that overlaps in frequency includes computing one or more time division multiple access (TDMA) time-slot channels to be shared between the first and second media for data transmission; allocating one or more time-slot channels to the first medium for data transmission; allocating one or more of the remaining time-slot channels to the second medium for data transmission; and instructing transceivers for the first and second media to communicate only in their allocated time-slot channels.

Claims

1. A method for data transmission over first and second media that overlaps in frequency, comprising.

computing one or more time division multiple access (TDMA) time-slot channels to be shared between the first and second media for data transmission;

allocating one or more time-slot channels to the first medium for data transmission;

allocating one or more of the remaining time-slot channels to the second medium for data transmission; and

instructing transceivers for the first and second media to communicate only in their allocated time-slot channels.

2. The method of claim 1, wherein one of the medium conforms to an 802.11 specification.

3. The method of claim 1, wherein one of the medium conforms to a Bluetooth specification.

4. The method of claim 1, wherein the first and second media operates at approximately 2.4 gigahertz.

5. The method of claim 1, further comprising:

(a) determining a desired level of service for one of the media during a transmission; and

(b) dynamically adjusting a number of time slots assigned to the media during the transmission to remain within limits of said desired level of service.

6. The method of claim 5, wherein the dynamic adjusting comprises:

determining available time-slot resources;

detecting the medium that fails to meet said desired level of service,

allocating the medium to a configuration having a additional time slots,

transmitting an additional channel assignment message including information on the allocated configuration with the additional time slots.

7. The method of claim 5, further comprising instructing transceivers for the first and second media to communicate only in their newly allocated time-slots.

8. A method for data transmission over first and second media that overlaps in frequency, comprising:

selecting one of the first and second media as a common medium; and

routing the data transmission through the common medium

9. The method of claim 8, wherein one of the medium conforms to an 802.11 specification.

10. The method of claim 8, wherein one of the medium conforms to a Bluetooth specification

11. The method of claim 8, wherein the first and second media operates at approximately 2.4 gigahertz.

12. A method for data transmission over first and second media that overlaps in frequency, comprising:

selecting one of the first and second media as a common medium;

instructing transceivers for the first and second media to communicate only through the common medium

13. The method of claim 12, wherein one of the medium conforms to an 802 11 specification.

14. The method of claim 12, wherein one of the medium conforms to a Bluetooth specification.

15. The method of claim 12, wherein the first and second media operates at approximately 2.4 gigahertz.

16. The method of claim 12, wherein a packet is initially transmitted at the highest rate supported by both media.

17. The method of claim 16, further comprising retrying the packet at the next lower rate if the packet is not successfully acknowledged.
