The electromagnetic field strengths of fixed radio-frequency transmitters, as determined by a sur-
vey of the electromagnetic environment (a), must be below the compliance level for each frequency
range. Interference may occur close to equipment identified by the following symbol:
Comment: These specifications may not apply in all situations. Electromagnetic propagation is affect-
ed by absorption and reflection from structures, objects and people.
(a) The electromagnetic field strengths of fixed radio-frequency transmitters, such as base stations for
mobile phones (cellular/wireless), mobile radios, amateur radio operators, AM/FM radio broadcasts
and TV broadcasts cannot be determined accurately through theory. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be carried out. If the
