Footnotes


5.150 The following bands:

13553-13567 kHz(centre frequency 13560kHz),
26957-27283 kHz(centre frequency 27120 kHz),
40.66-40.70 MHz(centre frequency 40.68 MHz),
902-928 MHzin Region 2 (centre frequency 915 MHz),
2400-2500 MHz(centre frequency 2450 MHz),
5725-5875 MHz(centre frequency 5800 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.

US211 In the bands 1670-1690, 5000-5250 MHz and 10.7-11.7, 15.1365-15.35, 15.4-15.7, 22.5-22.55, 24-24.05, 31.0-31.3, 31.8-32.0, 40.5-42.5, 116-122.25, 123-130, 158.5-164, 167-168, 191.8-200, and 252-265 GHz, applicants for airborne or space station assignments are urged to take all practicable steps to protect radio astronomy observations in the adjacent bands from harmful interference; however, US74 applies.
