Table 9.5 Separation Distance Table
RF communication equipment (transmitters) and the Atomlab 500 as recommended below,
according to the maximum output power of the communication equipment.
Rated Maximum
Output Power of
Transmitter [W] Separation Distance According to Frequency of Transmitter [m]
150 kHz to 80 MHz 80 MHz to 800 MHz 800 MHz to 2.5 GHz
d = 1.2 √ P d = 1.2 √ P d = 2.3 √ P
0.01 0.12 0.12 0.23
0.1 0.38 0.38 0.73
1 1.2 1.2 2.3
10 3.8 3.8 7.3
100 12 12 23
For transmitters rated at a maximum output power not listed above, the recommended
separation distance (d) in meters (m) can be estimated using the equation applicable to the
frequency of the transmitter, where P is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
