3.9 Quantum Wi-Fi only installation requirementsWhilst the Wi-Fi performance has been tested and proven in many different installation scenarios, therequirements below must be taken into consideration before choosing a location for the Quantum™Radar.In systems with multiple MFDs, the Radar should be connected to the MFDs that are located closestto it, or to the MFDs with the clearest line of sight to the Radar.The maximum distance between MFD and Radar will vary depending on the installation environment(i.e. obstructions and interference).Example 1 — Open air, line-of-sight in optimum conditionsIn optimum open air, clear line-of-sight conditions a reliable connection is possible at distances upto 100 m (328 ft). However, there are many factors that can influence this, so a pre-installation sitesurvey should always be performed. For reliable Wi-Fi performance the signal strength should bebetter than –75dBm. The closer the signal is to zero the better the Wi-Fi performance will be (e.g.–40dBm is better than –75dBm). You can assess the potential signal strength at the desired locationduring the Pre-installation Site Survey using a Wi-Fi Analyzer app on your smart device.Planning the installation 31
