Using poorly adjusted transmission devices that transmit outside their assigned
frequency or produce an electromagnetic signal that interferes with a signal
transmission;
Existing electronic sources and uses created by portable systems affecting entire
communities utilizing Wi‐Fi broadband systems; and
Industrial sources that produce electronic noise by‐product.
The military relies on a range of frequencies for communications and support systems.
Since 1993, Congress has been selling federal spectrum bands for reallocation to the
private sector, promoting the development of new telecommunications technologies,
products and services. The expanding public and commercial use of the frequency
spectrum from wireless transmitters to consumer electronics can encroach on the
military’s use of the frequency spectrum. Increasing community and DoD demands for
this important resource can create conflicts for all users.

FSI‐1
AZARNG Site: There may be increased unmanned aerial
system training in Pinal County in the future.
Entire JLUS
Project Area
There is a potential for the DoD and defense
contractors to increase testing and training of
unmanned aerial systems (UAS) at Florence
Military Reservation, as well as at other AZARNG.
The use of UASs relies heavily on radio
communication between the UAS operator and
the aircraft. Future growth in the region that is
not coordinated with the military may impact this
communication.
Compatibility Assessment
Issue LAS‐1 provides additional information on UAS activities at FMR including restricted
area airspace around the installation and Federal Aviation Administration (FAA) / DoD
rules and regulations regarding UAS operation.
UASs are controlled wirelessly using radio frequencies (RF), which are invisible wave
forms on the electromagnetic spectrum. Radio frequency is measured in hertz (Hz)
where extremely low frequency is anywhere from 3Hz to 30Hz and tremendously
high frequency is 300 giga‐hertz (GHz) – 3000 GHz. The Federal Communications
Commission regulates unlicensed wireless equipment, via Part 15 rule, using ISM
(industrial / scientific / medical) RF bands. The ISM RF bands are:
5-40
