. Thus, the maximum permissible exposure for general population/
uncontrolled exposure at 915MHz is 2.77 W/m
2
. The average time is 6 minutes. The maximum
permissible exposure (MPE) is the following:
Controlled Environment
Power density = 0.6455*frequency(in MHz)

with a Reference Period time of 6 Min
General Public/Uncontrolled Environment
Power density = 0.02619*frequency(in MHz)

with a Reference Period time of 6 Min
Using the frequency (in the middle of the band of operation of this equipment) of 915MHz and the
highest antenna gain that this equipment is certified for use in a final installation, the minimum
safe distance was calculated. The MPE minimum distances are 18in (45cm) for the Controlled
environment and 47in (120cm) for the General Public/Uncontrolled environment.
TransCore Recommendation on MPE (Maximum Permissible Exposure)
The calculated power densities and MPE distance for each of the agencies respective to the
environment is shown below.
