Wi-Fi Location Requirements; Pre-Installation Site Survey - Wi-Fi Analyzer - Raymarine Quantum 2 Installation Instructions Manual

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.
Line of sight and obstacles
For best results the Wi-Fi product should have a clear, direct line of sight to the product it will be
connected to. Any physical obstructions can degrade or even block the Wi-Fi signal.
The construction of your vessel can also have an impact on Wi-Fi performance. For example, metal
structural bulkheads and roofing will reduce and in certain situations, block the Wi-Fi signal.
If the Wi-Fi signal passes through a bulkhead containing power cables this can also degrade Wi-Fi
performance.
Reflective surfaces such as metal surfaces, some types of glass and even mirrors can drastically
effect performance or even block the Wi-Fi signal.
Interference and other equipment
Wi-Fi products should be installed at least 1m (3 ft) away from:
• other Wi-Fi enabled products
• transmitting products that send wireless signals in the same frequency range
• other electrical, electronic or electromagnetic equipment that may generate interference
Interference from other peoples Wi-Fi products can also cause interference with your products. You
can use a Wi-Fi analyzer tool to assess the best Wi-Fi channel (channel not in use or used by least
amount of devices) for you to use.
Pre-installation site survey — Wi-Fi Analyzer
Before installing a Quantum Radar, that will be connected using Wi-Fi, a site survey should be
performed to ensure the Wi-Fi Signal strength is sufficient to maintain a reliable connection.
It is recommended that you perform the site survey using a smart device and a Wi-Fi Analyzer app
(e.g. Wi-Fi Analyzer by Farproc for android devices).
