What to watch out for when designing a WLAN?

 

Although WLAN network gives many possibilities and has many advantages, each technology also has disadvantages. Some of them can be eliminated – but you need to know what to pay attention to. When building a WLAN, walls, doors, and windows can be obstacles. They cause a decrease in the quality of the signal, as well as its high attenuation. As a result, data download and upload may be extended. And in more difficult cases, even completely prevented by the lack of connection, visible in some places in the room – even despite the proximity of the access point.

In an open space, the WLAN network operates in an area from several hundred meters to several kilometers, depending on the power of the devices, antennas used and the visibility between devices. When building it, however, it is also worth taking into account a less optimistic scenario, i.e. a situation in which energy networks will be disturbed. And this may appear in the case of an accumulation of various electronic devices or other wireless networks (separate WLAN networks built by the closest neighbors may collide here). Such a densification of many networks can cause considerable difficulties as a result of their mutual interaction. It is also not easy in large production halls – an additional difficulty here is undoubtedly the accumulation of various types of machines that create electromagnetic fields themselves. The difficulty of this environment is also evidenced by the fact that it is often characterized by high dynamics – various “obstacles” for WLAN networks, for example a rotating / seasonal warehouse.

It is worth consciously choosing a solution (in terms of connecting to the network), as well as testing the network and analyzing the results in terms of channel occupancy, set on the controller. In this way, it is possible to detect the possible necessity to change them (the reason may be their mutual overlapping). Because while with just a few networks the quality may not be so bad, when increasing them the matter may become very complicated.

It is also worth taking security seriously. Therefore, a good solution here will be additional user verifications (for example by e-mail or SMS messages) and the use of the latest Wi-Fi Protected Access 2 encryption methods and the latest WPA3 standard.
