SYSTEM FOR ALLOCATING CHANNELS IN A MULTI-RADIO WIRELESS LAN ARRAY
First Claim
1. A method for allocating channels in a wireless access device having a plurality of radios capable of operating on a plurality of channels, each channel having a frequency band with a center frequency, each center frequency spaced at equal frequency intervals with a larger frequency band, where any one channel may have at least one adjacent channel located in the next frequency band, the method comprising:
- allocating one of the plurality of channels to each one of the plurality of radios, where each of the allocated channels is not adjacent to any one of the other allocated channels.

Abstract
A channel allocation system for allocating channels in a frequency band to a plurality of radios in close proximity so as to minimize co-channel interference. One method for allocating channels involves initially tuning each of the plurality of radios to the same one of the plurality of channels. All of the radios then receive signals from whatever sources and a signal score is determined for each radio. The radios are then tuned to another one of the plurality of channels. The steps of receiving a signal and determining a signal score for each radio are repeated for each of the remaining channels until all channels have been used. The signal scores are then tested against a table of mapping schemes to determine maximum isolation.

2. A method for allocating channels in a wireless access device having a plurality of radios capable of operating on a plurality of channels, each channel having a frequency band with a center frequency, each center frequency spaced at equal frequency intervals with a larger frequency band, where any one channel has at least one adjacent channel located in the next frequency band, the method comprising:
-
allocating one of the plurality of channels to each one of the plurality of radios, where each of the allocated channels is not adjacent to any one of the other allocated channels until at least one radio is not allocated a channel because the only channels remaining are adjacent to at least one allocated channel; and allocating a remaining channel to a radio having a radial separation of 90°
to 150°
from the radio having the allocated channel that is adjacent to the remaining channel.

3. A method for allocating channels in a wireless access device having a plurality of radios capable of operating on a plurality of channels, each channel having a frequency band with a center frequency, each center frequency spaced at equal frequency intervals with a larger frequency band, where any one channel has at least one adjacent channel located in the next frequency band, the method comprising:
-
allocating one of the plurality of channels to a first radio; allocating a second one of the plurality of channels a number nch channels away from the first one of the plurality of channels to an adjacent radio; allocating a third one of the plurality of channels a second number ncha of channels smaller than nch, to a next adjacent radio. - View Dependent Claims (4, 5, 6, 7, 8)

9. A method for allocating channels in a wireless access device having a plurality of radios capable of operating on a plurality of channels, the method comprising:
-
initially tuning each of the plurality of radios to the same one of the plurality of channels; receiving signals on all the radios; determining a signal score at each radio; tuning each of the plurality of radios to another one of the plurality of channels; receiving signals on all the radios; determining signal scores at each radio; repeating the steps of tuning, receiving and determining signal scores until all of the available channels have been used; and testing the signal scores against a table of mapping schemes to determine maximum isolation. - View Dependent Claims (10, 11, 12)
