      122-123 GHz (centre frequency 122.5 GHz), and
      244-246 GHz (centre frequency 245 GHz)

    are designated for industrial, scientific and medical (ISM) applications. The use of these frequency bands for ISM applications shall be subject to special authorization by the administration concerned, in agreement with other administrations whose radiocommunication services might be affected. In applying this provision, administrations shall have due regard to the latest relevant ITU R Recommendations.

  • 5.558   In the bands 55.78-58.2 GHz, 59-64 GHz, 66-71 GHz, 122.25-123 GHz, 130-134 GHz, 167-174.8 GHz and 191.8-200 GHz, stations in the aeronautical mobile service may be operated subject to not causing harmful interference to the inter-satellite service (see No. 5.43). (WRC 2000)

Industrial, Scientific, and Medical Devices (ISM, FCC Part 18)

Current Use 122–123 GHz ISM
Part 18 (section 18.301) of the FCC rules designate certain bands for high-power Industrial, Scientific, and Medical (ISM) devices. These devices generate significant radio energy, but not for telecommunications purposes. Examples includes microwave ovens, industrial heaters, medical diathermy, jewelry cleaners, and RFID tags.

ISM devices may be operated in most frequency bands subject to strict power limits, but are allowed unlimited power in these eleven specially-designated ISM bands.
