This allows for many devices to communicate with them at the same time. The gateways are placed on the northern corner and on the southern corner of the tower with antennas facing in all directions then. | This allows for many devices to communicate with them at the same time.

Because of the metal cage encompassing the upper platform of the tower, the antennas had to be placed at a distance, otherwise, their range might be impacted. With the help of the former miner **Jörg Kamps** from the HSRW FabLab Team, we together designed a simple holder and he could manufacture multiple ones made from stainless steel. These enabled us to specifically tune the distance from the metal cage for each individual antenna. Therefore we used our Network Analyzer which enables us to see the frequency at which the antennas are able to receive data. | Because of the metal cage encompassing the upper platform of the tower, the antennas had to be placed at a distance, otherwise, their range might be impacted.

The longest distance (//as of right now//) that was achieved was almost 8 kilometers long, which is far beyond the general Kamp-Lintfort Area. For us, this is a major success! You can check the current coverage with our north-facing gateway and its antennas here: [[https:// | The longest distance (//as of right now//) that was achieved was almost 8 kilometers long, which is far beyond the general Kamp-Lintfort Area.

The system is all powered through mains power provided by the tower itself. On the northern side, an electrical box is located where all the network and power distribution over PoE (Power over Ethernet) is done. The idea is to later add a redundant internet connection as well. | The system is all powered through mains power provided by the tower itself.
