Footnotes

  • 5.150   The following bands:

      13 553-13 567 kHz (centre frequency 13 560 kHz),
      26 957-27 283 kHz (centre frequency 27 120 kHz),
      40.66-40.70 MHz (centre frequency 40.68 MHz),
      902-928 MHz in Region 2 (centre frequency 915 MHz),
      2 400-2 500 MHz (centre frequency 2 450 MHz),
      5 725-5 875 MHz (centre frequency 5 800 MHz), and
      24-24.25 GHz (centre frequency 24.125 GHz)

    are also designated for industrial, scientific and medical (ISM) applications. Radiocommunication services operating within these bands must accept harmful interference which may be caused by these applications. ISM equipment operating in these bands is subject to the provisions of No. 15.13.

  • G59   In the bands 902-928 MHz, 3100-3300 MHz, 3500-3650 MHz, 5250-5350 MHz, 8500-9000 MHz, 9200-9300 MHz, 13.4-14.0 GHz, 15.7-17.7 GHz and 24.05-24.25 GHz, all Federal non-military radiolocation shall be secondary to military radiolocation, except in the sub-band 15.7-16.2 GHz airport surface detection equipment (ASDE) is permitted on a co-equal basis subject to coordination with the military departments.

Possible MSS Allocations (WRC-15 Agenda Item 1.10)

Proposed Use 22–26 GHz Possible MSS allocations (WRC-15 agenda item 1.10)
Agenda item 1.10 of the 2015 World Radiocommunication Conference:

"to consider spectrum requirements and possible additional spectrum allocations for the mobile-satellite service in the Earth-to-space and space-to-Earth directions, including the satellite component for broadband applications, including International Mobile Telecommunications (IMT), within the frequency range 22 GHz to 26 GHz, in accordance with Resolution 234 (WRC-12)"

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

Current Use 24–24.25 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.

Unlicensed Level Probing Radars

Proposed Use 24.05–29 GHz
The FCC has released a Notice of Proposed Rule Making that would allow downward-pointing, unlicensed level probing radars, for use both in tanks and outdoors, at 5.925-7.250, 24.05-29, and 75-85 GHz.

Proposed EIRP boresight emissions limits are:

5.925-7.250 GHz: -33 dBm/MHz average and +7 dBm across 50 MHz.
24.05-29 GHz: -14 dBm/MHz average and +26 dBm across 50 MHz
75-85 GHz: -3 dBm/MHz average and +34 dBm across 50 MHz

Proposed average emissions limits to the sides and upward are:

5.925-7.250 GHz: -55 dBm/MHz
24.05-29 GHz: -41.3 dBm/MHz
75-85 GHz: -41.3 dBm/MHz
