Wi-Fi Signal Reflection; Wi-Fi Location Requirements - Raymarine Quantum Radome Installation Instructions Manual

In the example above the maximum distance with
acceptable Wi-Fi performance was 15 metres (49
feet), 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 was 3 metres (9.8
feet), 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.

Wi-Fi Signal Reflection

When establishing a location for your Quantum
Radar, that will be connected using a Wi-Fi
connection, it is important to consider the effects
your surroundings can have on the Wi-Fi signal. The
Wi-Fi signal will reflect or 'bounce' off nearby objects
which may create an easier path for the signal to
Planning the installation
take, whilst your connection may appear reliable it
may quickly degrade when you take your vessel out
into open water.
Example
1. In this example the Wi-Fi signal is bounced off
a nearby vessel and back through the windows
on the bridge, this provides an easier path than
passing through the metal roof.
2. In this example the Wi-Fi signal is reduced when
passing through the metal roof. This, however
may be the only path the signal can take when
out in open water.
Warning: Quantum Wi-Fi
connection
During installation there will usually be
structure that effects the Wi-Fi signal.
Before using the Radar for navigation,
ensure you test the reliability of your Wi-Fi
connection in open waters and away from
any other vessels or structure.

Wi-Fi location requirements

A number of factors can influence Wi-Fi
performance, it is important to ensure you test the
Wi-Fi performance, at the desired location before
installing Wi-Fi enabled products.
Distance and signal strength
The distance between Wi-Fi products should always
be kept to a minimum. Do not exceed the maximum
stated range of your Wi-Fi product (Maximum range
will vary for each device).
Wi-Fi performance degrades over distance so
products farther away will receive less network
bandwidth. Products installed close to their
maximum Wi-Fi range may experience slow
connection speeds, signal drop outs or not being
able to connect at all.
