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.

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.
