-**Confirm a clear line of sight.** The electromagnetic waves of Wi-Fi links weaken significantly when they pass through objects, trees, and other obstacles. For this reason, it is important to verify that there is a clear line of sight between the two mounting points. The [Participatory Mapping of a Free, Community Network](https://conectividad.altermundi.net/documentacion/mapeo-participativo-de-una-red-libre-y-comunitaria/) material can be very useful.

-**Analyse the possible link on a map.** Look at a satellite map in advance, draw the line, and reference the alignment with something close-by that is visible to the naked eye.
-**Analyse the elevation profile of the terrain and assess the feasibility of the link.** In this profile, pay attention to the exact location of both antennas, the line of sight between them, the curvature of the Earth, and the Fresnel zone. There are link calculators that combine this data automatically — you only need to learn a little about how to use them. Two free options, for example, are [airLink](https://link.ui.com/) and [LigoWave](https://linkcalc.ligowave.com/Account/Login).

The goal is to reach a value as close to **0** (zero) as possible. This value represents the quality of the link, measured in dBm (decibel-milliwatts). It is always a negative number, so -65 means a better signal than -72.

**The key is to move the antenna slowly and millimetre by millimetre**, paying attention to the change of value on the screen.
In a mesh network, sometimes you decide to point at, or *illuminate*, an area or several nodes at once, instead of a single specific node. In that case, you can point at the most central node of the area of interest, and check that the signal level is acceptable at every node to be linked. Don't forget that all the involved nodes must use the same radio/antenna.
