Wi-Fi, perhaps the most widespread and well-known wireless technology used worldwide, is a wireless networking standard designed to provide communication between mobile devices or access and data exchange between servers using an IP connection. Wi-Fi operates in the ISM bands at 2.4 GHz and 5 GHz. Due to the maturity of this technology, many devices are certified for use in hazardous areas, compared to some newer wireless standards. Typically, Wi-Fi coverage outdoors is 10 times narrower, and indoors it is 4 times narrower than that of LTE/5G.

Explosion-proof Ex antennas Wi-Fi are designed for use in hazardous areas in industrial Wi-Fi applications. Available for 2.4 GHz, 5 GHz, 6 GHz.

When designing wireless networks for dense metal environments, it is necessary to consider the placement of wireless devices and the density required to achieve the required performance level. Radio signals reflect off metal structures, causing the wireless signal to be received by the receiver multiple times. This can result in the signals being received out of phase and canceling each other out. As a result, the connection becomes poor or completely absent. Technology, such as 802.11b/g WiFi was fine in line-of-sight applications but became useless as soon as it was deployed in heavy metallic environments with severe multipath interference. This was one of the main reasons that held up the deployment of WiFi in the process industries. The advent of 802.11n WiFi was a game changer in that it was the first WiFi standard to utilise this radio technology.

Simple and reliable Wi-Fi application technology for explosive production facilities. There is no need to use IS barriers that reduce the signal level by at least 2 dB.
