Where p is the maximum output power rating of the transmitter in watts (W) d – is the
minimum separation distance in (m). The field strength of the fixed RF transmitter is
determined by an electromagnetic site survey* of the electromagnetic field. Each frequency
range b should be lower than the current frequency.** Interference may occur win the
