| 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 |
