For the maximum rated output power of the transmitter not listed in the above table, the
recommended separation distance d in meters(m) can be determined by the formula in the
corresponding transmitter frequency column, where P is the maximum rated output power
of the transmitter provided by the transmitter manufacturer in watts (W).
Note 1: at 80 MHz and 800 MHz frequency points, the formula for the higher frequency
band is used.
Note 2: these guidelines may not be applicable in all cases. Electromagnetic propagation is
influenced by the absorption and reflection of buildings, objects, and human bodies.
Note 3: the ISM band between 50 kHz and 80 MHz refers to 6.765 MHz-6.795 MHz, 13.553
MHz-13.567 MHz, 26.957 MHz-27.283 MHz and 40.66 MHz-40.70 MHz.
Note 4: Factor 10/3 is used to calculate the recommended separation distance for the
transmitters in the 150 kHz-80 MHz's ISM band and 80 MHz-2.5 GHz frequency range to
reduce the possibility of interference when portable/mobile RF communication equipment
is accidentally brought into the patient area.
