For transmitters rated at a maximum output power not listed above, the rec-
ommended separation distance ’d’ in meters (m) can be estimated using the
equation applicable to the frequency of the transmitter, where ’P’ is the max-
imum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
• REMARK 1: At 80MHz and 800MHz, the separation distance for the
higher frequency range applies.
• REMARK 2: These Guidelines may not be relevant in all situations. The
dispersion of electromagnetic waves is influenced by absorption and re-
flections from buildings, objects and people.
