For the transmitter rated maximum output power not listed in the above table, the
recommended isolation distance d
, in meters (m), can be determined by the formula in the
corresponding transmitter frequency column, Here P is the maximum output rated power of the
transmitter provided by the transmitter manufacturer, in watts (W).
Note 1
：At 80 MHz and 800 MHz, the higher frequency range formula is used.
Note 2 ：
These guidelines may not be suitable for all situations. Electromagnetic
propagation is affected by absorption and reflection from buildings, objects, and humans.
