Abstract

A method is provided for making a quality determination for a plurality of signal channels in an ultrawide bandwidth local network that will not require a coordinator associated with the network to suspend network operation. This is achieved by having the coordinator send a channel quality request to a non-coordinator device in the network. This non-coordinator device then performs a channel quality determination to determine channel quality information about the plurality of signal channels. After it has completed the channel quality determination, the non-coordinator device then sends the channel quality information from the non-coordinator device to the coordinator device. And if the non-coordinator device can accomplish the channel quality determination quickly enough, it need not even remove itself from the network, even temporarily.

Claims

1. A method of making a quality determination for a plurality of signal channels in a wireless network, comprising:

sending a channel quality request from a coordinator device in the network to a non-coordinator device in the network;

performing a channel quality determination at the non-coordinator device to determine channel quality information about the plurality of signal channels; and

sending the channel quality information from the non-coordinator device to the coordinator device.

2. A method of making a quality determination for a plurality of signal channels in a wireless network, as recited in claim 1, wherein the step of performing the channel quality determination is accomplished by having the non-coordinator device monitor each of the plurality of signal channels in turn.

3. A method of making a quality determination for a plurality of signal channels in a wireless network, as recited in claim 1, wherein each of the plurality of signal channels has a different carrier frequency.

4. A method of making a quality determination for a plurality of signal channels in a wireless network, as recited in claim 1, wherein each of the plurality of signal channels has a different center frequency.

5. A method of making a quality determination for a plurality of signal channels in a wireless network, as recited in claim 1, wherein each of the plurality of signal channels operates using a unique CDMA code.

6. A method of making a quality determination for a plurality of signal channels in a wireless network, as recited in claim 1, wherein each of the plurality of signal channels has a different combination of center frequency and CDMA code.

7. A method of making a quality determination for a plurality of signal channels in a wireless network, as recited in claim 1, wherein the non-coordinator device suspends normal operation during the step of performing channel quality determination.

8. A method of making a quality determination for a plurality of signal channels in a wireless network, as recited in claim 1, wherein the non-coordinator device does not participate in communication with the network during the step of performing the channel quality determination.

9. A method of making a quality determination for a plurality of signal channels in a wireless network, as recited in claim 1, wherein the channel quality information indicates the presence or absence of radio frequency interference in each signal channel.

10. A method of making a quality determination for a plurality of signal channels in a wireless network, as recited in claim 9, wherein the channel quality information further indicates the periodicity of any radio frequency interference in each signal channel.

11. A method of making a quality determination for a plurality of signal channels in a wireless network, as recited in claim 1, wherein the wireless network is an ultrawide bandwidth network.

12. A method of making a quality determination for a plurality of signal channels in a first wireless network, comprising:

sending a channel quality request from a coordinator device in the local network to a non-coordinator device in the network;

performing a channel quality determination at the non-coordinator device to determine channel quality information about the plurality of signal channels; and

sending the channel quality information from the non-coordinator device to the coordinator device,

wherein the channel quality information indicates the presence or absence of one or more overlapping wireless networks on one or more of the plurality of signal channels.

13. A method of making a quality determination for a plurality of signal channels in a wireless network, as recited in claim 12, wherein the step of performing the channel quality determination is accomplished by having the non-coordinator device monitor each of the plurality of signal channels in turn.

14. A method of making a quality determination for a plurality of signal channels in a first wireless network, as recited in claim 12, wherein the channel quality information further indicates the identities of any overlapping wireless networks.

15. A method of making a quality determination for a plurality of signal channels in a first wireless network, as recited in claim 12, wherein the channel quality information further indicates the presence or absence of radio frequency interference.

16. A method of making a quality determination for a plurality of signal channels in a first wireless network, as recited in claim 15, wherein the channel quality information further indicates the periodicity of any radio frequency interference.

17. A method of making a quality determination for a plurality of signal channels in a first wireless network, as recited in claim 12, wherein each of the plurality of signal channels has a different carrier frequency.

18. A method of making a quality determination for a plurality of signal channels in a first wireless network, as recited in claim 12, wherein each of the plurality of signal channels has a different center frequency.

19. A method of making a quality determination for a plurality of signal channels in a first wireless network, as recited in claim 12, wherein each of the plurality of signal channels operates using a unique CDMA code.

20. A method of making a quality determination for a plurality of signal channels in a first wireless network, as recited in claim 12, wherein each of the plurality of signal channels has a different combination of center frequency and CDMA code.

21. A method of making a quality determination for a plurality of signal channels in a first wireless network, as recited in claim 12, wherein the first wireless network and any overlapping wireless networks are ultrawide bandwidth networks.
