1  Device boundary of a radiocommunications transmitter
 (1) The device boundary of a single radiocommunications transmitter is established as follows:
         Step 1: Calculate the device boundary criterion at each m×100 metre increment along each of the n-degree radials, where:
                 m is each of the integers from 1 through 400; and
                 n is each of the integer degrees from 0 (true north) through 359.
         Step 2: For each radial, find the latitude and longitude of the first point on the radial, moving away from the location of the radiocommunications transmitter (that is, with the lowest value of m) where either:
                (a) the device boundary criterion, RP-MP, is less than or equal to 0; or
                (b) m is equal to 400.
         This point is the end point of the radial.
         Step 3: The end point of each radial is the device boundary of the radiocommunications transmitter connected to that radial.
Note: RP – MP (the device boundary criterion) is calculated under item 2 of this Schedule.
 (2) For a group of radiocommunications transmitters the device boundary is calculated as if for a single radiocommunications transmitter. However, the radiated power (RP) for a group of radiocommunications transmitters is taken:
(a) to be equal for each bearing σn; and
                (b) to have a value that is equal to the maximum horizontally radiated power, in any direction, of any of the radiocommunications transmitters in the group.
Note: n is the bearing of the nth-degree radial for the group of radiocommunications transmitters.
