Separation Distance (meters) According to Frequency of Transmitter
1
150 kHz to 80 MHz
d (meters) = 3.5/V1 x √ P
d (meters) for V1 = 3 Vrms
80 MHz to 800 MHz
2
d = 3.5/E1 x √ P
d for E1 = 3 V/m
800 MHz to 2.5 GHz
d = 7/E1 x √ P
d for E1 = 3 V/m

NOTE:
1
These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
2
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
For transmitters rated at a maximum output power not listed above, estimate the recommended
separation distance d in meters (m) using the equitation 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.
