-Anyone in the area can now deploy their own LoRaWAN devices, transmit the data to their own TTN application and expect good coverage. We installed two gateways with two rod antennas each on the platform of the Friedrich-Heinrich coal mine tower. The antenna pairs are installed at the south-west as well as the north-east corner of the tower, respectively.  +Anyone in the area can now deploy their own LoRaWAN devices and use the new gateways for free to transmit data to their own TTN applications.

-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.+| {{:blog:go_photo_1664893930174.jpg?600&direct}}                                                             |

 In the end, we were able to tune them just right. The first insight into the coverage we are able to achieve is shown by [[https://ttnmapper.org|TTN Mapper]]. This also is a community-driven project, where everyone is able to test the coverage of the TTN.  In the end, we were able to tune them just right.

 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://ttnmapper.org/radar/gateway/?gateway=eui-ac1f09fffe058d7c&network=NS_TTS_V3://ttn@000013|TTN Mapper]]  The longest distance (//as of right now//) that was achieved was almost 8 kilometers long, which is far beyond the general Kamp-Lintfort Area.

 As of writing this there where no test done yet on the southern gateway. As of writing this there where no test done yet on the southern gateway.

 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.
