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