The ISM (industrial, scientific and medical) bands between 0,15 MHz and 80 MHz
are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283
MHz; and
40,66 MHz to 40,70 MHz. The amateur radio bands between 0,15 MHz and 80
MHz are 1,8 MHz to 2,0 MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz to 5,4 MHz, 7 MHz to
7,3 MHz, 10,1
MHz to 10,15 MHz, 14 MHz to 14,2 MHz, 18,07 MHz to 18,17 MHz, 21,0 MHz to
21,4
MHz, 24,89 MHz to 24,99 MHz, 28,0 MHz to 29,7 MHz and 50,0 MHz to 54,0
MHz.
b The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz
and in the frequency range 80 MHz to 2,7 GHz are intended to decrease the
likelihood that mobile/portable communications equipment could cause
interference if it is inadvertently brought into patient areas. For this reason, an
additional factor of 10/3 has been incorporated into the formulae used in
calculating the recommended separation distance for transmitters in these
frequency ranges.
c Field strengths from fixed transmitters, such as base stations for radio
(cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM
radio broadcast and TV broadcast cannot be predicted theoretically with accuracy.
To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in
