The recommended protection ratio can be calculated in meters (m) for transmitters whose maximum nominal
output is not specified in the table above. To do so, use the equation for the column in question, where P is the
maximum nominal output of the transmitter.
NOTE 1: The higher frequency range applies for 80 MHz and 800 MHz.
NOTE 2: These guidelines may not apply in all cases. The diffusion of electromagnetic parameters is affected by
absorption and reflections from buildings, objects and people
