GSM Channel Mapping Notes

Some NICs/devices use downconverters to map normal 2/5ghz channels to 900mhz GSM/ISM bands.

The below list is mostly so the mappings for (unsupported) devices aren't forgotten.

For HT5 mode:
907(2427)
912(2432)
917(2437)
922(2442)

For HT10 mode: 
907(2427)
912(2432)
917(2437)
922(2442)

For HT20 mode:
912(2432)
917(2437)
