Good practices in building WLAN networks


It is worth remembering about WLAN project itself. This is because it can show the possibilities of the network from the very beginning, as well as predict various scenarios that may turn out to be helpful in the future. Such a preliminary design also enables a quick reaction to any difficulties.

It is also good practice to rethink the WLAN installation itself. It can be made in several variants – for example:

  1. wired connection of access points to a network switch,
  2. via the Internet, e.g. by setting up a VPN connection, etc. using the Internet provided by cable TV, xDSL or via the Mobile Internet,
  3. wirelessly building a bridge connecting 2 or more access points (point – point or point – multipoint),
  4. MESH technology (lattice), often used in places where there is a problem with adding computer cables, e.g. opencast mines, transhipment ports, parking lots for newly manufactured cars.

When designing a new or expanding the existing WLAN network, it is worth considering the location of access points. This should be done in such a way that the signal level (or rather the signal strength to noise ratio) is at least satisfactory at all points. For example, the thickness of the walls may be of key importance – whether they are only partitions that should not suppress radio waves, or thick walls, which unfortunately increase such a risk. It is therefore worthwhile to carry out an on-site inspection right from the start and check how the Wi-Fi networks of neighboring rooms affect our WLAN network. It is also worth considering the possible accumulation of electronic equipment, because this can also be an obstacle – with a few basic rules, however, it can be overcome.

When this issue is resolved, it is worth focusing on security. These, of course, will vary depending on the needs your WLAN generates. It will be different in the production hall, in a public area in the library, and in a single-family house. Here, for example, domain login, user identification via e-mail or SMS text messages or the use of a guest portal.

When building a closed network – one intended only for a specific group of employees – it is worth choosing those access points and cards that are at least compatible with the WPA standard. However, when building an open network – it is good to pay attention to the equipment designed for hot-spots, because it allows you to easily configure clients and provide protection against hacker attacks.
