3. RF Interference
All wireless devices, including satellite telephones, are susceptible to
RF (radio frequency) interference from other electronic devices. This
problem is more evident when numerous antennas and broadcasting
devices are located within close proximity to each other.
Symptoms of RF Interference
Symptoms of RF interference often resemble those that arise when
an Iridium phone is being operated with an obstructed view of the
sky.
Some of these symptoms include; erratic or no signal strength
indication dropped calls or warbled or otherwise distorted voice.
These symptoms may be intermittent or persistent, depending
largely on the interference source, its distance, strength and
frequency relative to the Iridium unit.
Mitigation of RF Interference
Iridium Service degradation due to RF interference can be
significantly improved by:
Increasing the distance and moving the Iridium antenna
»
off axis from the source of the interference, and
Using an external band pass filter and an external

antenna.
