For transmiers rated at a maximum output power not listed above the recommended
separaon distance d in metres (m) can be esmated using the equaon applicable to the
frequency of the transmier, where P is the maximum output power rang of the transmier
in was (W) according to the transmier manufacturer.
Note 1: At 80 MHz and 800 MHz, the separaon distance for the higher frequency range
applies.
Note 2: These guidelines may not apply in all situaons. Electromagnec propagaon is
aected by absorpon and reecon from structures, objects and people.
