Health Limits
Within the United States, environmental guidelines regulating safe exposure levels are issued by the Occu-
pational Safety and Health Administration (OSHA).
For equipment operating from 300 to 1500 MHz the FCC limits on radiation exposure are contained in
CFR title 47 part 1.1310.
Note: Frequency (f) is expressed in MHz.
At 902 MHz (worst case frequency for MPI 6000 operating band) these levels are
RF Levels From TransCore Equipment
Power density is given in milliwatts per centimeter (mW/cm) and is calculated as
where
P = antenna input power (mW)
G = antenna gain referenced to an isotropic radiator
D = distance from antenna (cm)
For TransCore’s IT2200 AVI system at maximum levels of
P = 1 W or 1000 mW, maximum
G = 14dBi or 25.1; AA3152 Universal Toll Antenna
