NOTATION 1. High frequencies are used at 80 MHz and 800 MHz.
NOTATION 2. These recommendations may not apply in all situations. Electromagnetic propagation affects
the absorption and reflection of structures, objects and people
The available power of fixed transmitters, such as base stations for radio (mobile / wireless) telephones and
*
mobile radios, radio amateurs, as well as AM and FM radio and television broadcasts, is theoretically
impossible to predict the accuracy. To assess the electromagnetic environment associated with fixed radio
frequency transmitters, electromagnetic radiation should be considered. If the measured field strength at the
place where the System is used exceeds the appropriate level, the device should be monitored for normal
operation. If abnormal operation is observed, additional measures may be required, such as reorienting or
moving the device
.
In the frequency range from 150 kHz to 80 MHz, the field strength must be less than [3] V / m

For transmitters rated at the maximum output power not specified above, the recommended distance in
meters (m) can be estimated using the equation applied to the transmitter frequency, where P is the
maximum transmitter output power in watts (W) according to the transmitter manufacturer.
