| 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 |
