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 signicantly
improved by:
a. Increasing the distance and moving the Iridium antenna off axis
from the source of the interference, and
b. Using an external band pass lter and an external antenna.
