Recommended Distance between Portable/mobile Radio
Frequency Communication Equipment and Kestrel 3100m
Kestrel 3100m is designed especially for using at the controlled electromagnetic environment with
radio frequency interference.
Customers and users can maintain one of following recommended minimum distances between
portable /mobile radio frequency communication equipment (transmitter) and Kestrel 3100m
based on the maximum output of communication equipment, and thus avoid the electromagnetic
interference.
Maximum rated
output of the
transmitter (W)
depends on the
frequency distance
of transmitters (m)
150 kHz~80 MHz
d=1.2
80 MHz~800
MHz
d=1.2
800 MHz~2.5 GHz
d=2.3
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 the maximum rated output of transmitter not listed in the foregoing list, it's recommended to
adopt isolation distance (d), with the unit of meter (m), which can be determined by the formula
concerned with the frequency of corresponding transmitters, wherein, "P" refers to the maximum
rated output of transmitter provided by the transmitter manufacturer, with the unit as watt (W).
Comment 1: When the frequency is between 80MHz and 800MHz, a higher frequency range shall
be applicable.
Comment 2: This guidance may not be applicable to all the conditions, since the electromagnetic
propagation is under the influence of buildings, objects and absorption and reflection of human
bodies.
