24 List of supported frequency ranges in KHz. This can be used for devices
25 that in a given config support less channels than normally. It may happen
26 chipset supports a wide wireless band but it is limited to some part of
27 it due to used antennas or power amplifier. An example case for this
28 can be tri-band wireless router with two identical chipsets used for two
29 different 5 GHz subbands. Using them incorrectly could not work or
30 decrease performance noticeably
