Example 2 — Signal passing through Fiberglass coach roof
In the example above the maximum distance with acceptable Wi-Fi performance is 15 m (49 ft), due
to the heavy fiberglass coach roof that the signal has to pass through.
Example 3 — Signal passing through heavy structure
In the example above the maximum distance with acceptable Wi-Fi performance is 3 m (9.8 ft), due to
the metal roof that the signal has to pass through.
Obstacles in the direct line of sight between the Radar and MFD will further impact Wi-Fi Performance.
The impact of each obstacle is usually minimal, however the effect is cumulative. Obstacles can
include but are not limited to:
•
Vessel structure
— Where the Wi-Fi signal passes through a vessel bulkhead or a coach roof, the
Wi-Fi performance will be impacted. Depending on the material and thickness of the structure the
impact may be severe; for example, a thick steel bulkhead may completely block the Wi-Fi signal.
•
Radar mounting
— The type of installation can impact performance; for example, mounting on a
solid steel platform will have a greater impact on performance than mounting on a bar-style mount.
•
Electrical equipment and other objects
— Any object in the direct line-of-sight between the Radar
and MFD can impact Wi-Fi performance. Electrical, electronic and electromagnetic devices will
have a greater impact than furniture.
•
MFD installation
— MFD installation can also impact Wi-Fi performance; for example, if the MFD is
surface mounted in a steel construction dash, the Wi-Fi performance will be impacted.
