The antenna connected to the product is specific to the deployment. The worst c ase scenario
occurs when using a very high gain outdoor/indoor antenna. However a typical indoor antenna is
shown in the following example:
The highest expected output power is 35.1 dBm at 772MHz. For an output level of 35.1 dBm with
an indoor antenna gain of 2.5 dBi, the EIRP is 37.6 dBm.
The maximum power density safe exposure level for general population/uncontrolled exposure of
30 minutes for the frequency of 772 MHz is 0.515 mW/cm

As shown above, the minimum s a f e distance where the MPE limit is reached is 30 cm from
the unit with a 2 . 5 dBi antenna and no distribution loss.
The antenna used in the above table is a Galtronics PEAR S5491i with 2.5 dBi gain in the
700 MHz band.
If the antenna will be positioned closer to end users than 30 cm, then the installer must calculate
the safe distance for a given installation using the formulas provided.
Band 3: 800 MHz
In the Frequency Range of 300 to 1500 MHz, the maximum power density limit for the
occupational/controlled exposures is f/300 mW/cm

for an average time of 6 minutes.
In the Frequency Range of 300 to 1500 MHz, the maximum power density limit for the general
population/uncontrolled exposures is f/1500 mW/cm

for an average time of 30 minutes.
The antenna connected to the product is specific to the deployment. The worst case scenario
occurs when using a very high gain outdoor/indoor antenna. However a typical indoor antenna is
shown in the following example:
The highest expected output power is 35.5 dBm at 860.9875MHz. For an output level of 35.5 dBm
with an indoor antenna gain of 3.5 dBi, the EIRP is 39 dBm.
The maximum power density safe exposure level for general population/uncontrolled exposure of
30 minutes for the frequency of 860.9875 MHz is 0.574 mW/cm
