1.4.Compliance
1. Notice: For installations, which have to comply with FCC RF exposure
requirements, the antenna selection and installation must be completed in a way
to ensure compliance with those FCC requirements. Depending on the RF
frequency, rated output power, antenna gain, and the loss between the repeater
and antenna, the minimum distance D to be maintained between the antenna
location and human beings is calculated according to this formula:
]/
[
][
][
2
4
cm
mW
mW
cm
PD
P
D∗
∗
=
π
where
•P (mW) is the radiated power at the antenna, i.e. the max. rated repeater
output power in addition to the antenna gain minus the loss between the
repeater and the antenna.
•PD (mW/cm²) is the allowed Power Density limit acc. to 47 CFR 1.1310 (B)
for general population / uncontrolled exposures which is
oF (MHz) / 1500 for frequencies from 300MHz to 1500MHz
o1 for frequencies from 1500MHz to 100,000MHz
RF exposure compliance may need to be addressed at the time of licensing, as
required by the responsible FCC Bureau(s), including antenna co-location
requirements of 1.1307(b)(3).
2. Notice:For installations which have to comply with European EN50385 exposure
compliance requirements, the following Power Density limits/guidelines (mW/cm²)
according to ICNIRP are valid:
o0.2 for frequencies from 10 MHz to 400 MHz
oF (MHz) / 2000 for frequencies from 400 MHz to 2 GHz
o1 for frequencies from 2 GHz to 300 GHz
3. Notice: Installation of this equipment is in full responsibility of the installer, who
has also the responsibility, that cables and couplers are calculated into the
maximum gain of the antennas, so that this value, which is filed in the FCC Grant
and can be requested from the FCC data base, is not exceeded. The industrial
boosters are shipped only as a naked booster without any installation devices or
antennas as it needs for professional installation.
