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.
