This is a configuration used for events, when you don't have a multi-beam antenna to install on a temporary BTS, but wish to replicate the effect of having multiple beams. Every antenna creates a beam in a particular direction with a given number of cells, so you can have for instance 15 4G cells defined with this configuration, 3 in each antenna. Normally, you space them using a certain constant shift in the azimuth, for instance 15 degrees difference between each antenna, so that the beams don't overlap. Tilt is used to control the direction of the beams of the antennas, just as if they were used vertically. In practice, this setup creates a lot of interference between cells, as the beams are not narrow and confined as in a 'real' multi-beam antenna. You will have a lot of cells, and they will process traffic, but the performance is poor because of the interference. And it's very confusing to manage, as you can easily antecipate. Avoid this configuration.

🔍 Un coup d'œil sur une configuration inhabituelle ! Sur cette photo, vous pouvez observer des antennes de télécommunication installées horizontalement, une méthode peu conventionnelle qui pique notre curiosité... #telecom #4G
