 ====== Zeche Friedrich-Heinrich: Kamp-Lintfort wide Open LoRaWAN deployed! ======
-(Jan Sonntag, Rolf Becker, 2022-10-19)
+(Jan Sonntag, Shreya Gupta, Rolf Becker, 2022-10-19)
 Kamp-Lintfort is now covered by the community-driven **open LoRaWAN** network of **[[https://www.thethingsnetwork.org/|The Things Network]] (TTN)!**
 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.
-Our **first application** is the data collection of our own **[[eolab:lineg:groundwater:start|groundwater gauges]]** developed with and for **LINEG.**

 ===== It's all coming together =====

-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.

 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.

 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.

 More tests with the system will be done in the near future.
