Assuring Quality of Inmarsat Service

Inmarsat is committed to providing subscribers
around the world with consistent, reliable, quality
voice and data access all day, every day. The
Inmarsat satellite system is monitored for call
performance from numerous locations 24 hours a
day, 7 days a week in order to achieve this. There
are conditions that can compromise the quality of
the service you may receive. These include:
• Obstructions
• Cabling
• RF Interference
Obstructions
Nearby tall buildings or similar structures,
heavily leafed trees and mountains can all
degrade performance as they block the signal
between the antenna and the satellites.
Inmarsat performance is immune from natural
environments such as clouds, fog, rain, snow,
wind and smoke.
Cabling
Using an externally mounted antenna provides
an ideal solution for many applications. It is very
important that both the antenna cabling and
antenna are Beam approved products. Always
ensure all RF connectors are screwed together firmly
and ensure there are no sharp bends in the cabling
between the docking station and the antenna.
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 antenna 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 Inmarsat unit.

Mitigation of RF Interference
Inmarsat Service degradation due to RF
interference can be significantly improved by:
• Increasing the distance and moving the
Inmarsat antenna off axis from the source
of the interference, and
• Using an external band pass filter and an
external antenna.
WARNING
Failure to use Beam approved antenna cables will
result in degraded performance and may damage
the IsatPhone Pro.
