RF Communications Equipment

Electromagnetic Environment
Portable and mobile RF communications equipment can affect the systems.
The Curve system is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled.
The Curve system user can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the
Curve system as recommended below, according to the maximum output power of the
communications equipment.
Separation Distances
Recommended separation distances between portable and mobile RF communications equipment
and the Curve system:
Rated Maximum Out-
put Power of Trans-
mitter (W)
0.01
0.1
1
10
100
For transmitters rated at a maximum output power not listed above, the recommended separa-
tion distance d in meters (m) can be determined using the equation applicable to the frequency
of the transmitter, where P is the maximum output power rating of the transmitter in watts (W)
according to the transmitter manufacturer.
NOTE: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
