 + 
 +===== Hardware ===== 
 + 
 +The intial thoughts about gateway hardware is to go the DIY route to gain as much knowledge about the components and the TTN/LoRa technologies as possible. 
 + 
 + 
 +==== Raspberry Pi + IMST iC880A ==== 
 + 
 +The iC880A is A 868MHz LoRa concentrator board using SX1301 and 2 SX1257 chips which is available now for EUR ~150. 
 + 
 +The [[https://​github.com/​ttn-zh/​ic880a-gateway/​wiki|DIY gateway ​from ttn-zh (Zürich) ​based on the iC880A]] looks like an easy, capable and and relatively cheap solution ​([[https://​www.coredump.ch/​2017/​05/​18/​our-ttn-gateway-in-rapperswil-is-live/​|blogpost about this solution]]). 
 + 
 +[[https://​github.com/​ttn-liv/​rpi-gateways|Ttn-liv (Liverpool) has forked]] this setup, it should be investigated how this differs from ttn-zh.

 +  * iC880A shop; http://​webshop.imst.de/​ic880a-spi-lorawan-concentrator-868mhz.html 
 +  * iC880A backplane for Raspberry Pi; https://​www.tindie.com/​products/​gnz/​imst-ic880a-lorawan-backplane-kit/​ 
 + 
 +=== Notes === 
 + 
 +  * [[https://​www.thethingsnetwork.org/​forum/​t/​ic880a-concentrator-with-raspberry-pi-gateway/​1897/​22|This TTN forum thread]] suggest an [[http://​www.ebay.com/​itm/​Geekworm-UPS-HAT-Board-2500mAh-Lithium-Battery-For-Raspberry-Pi-3-Model-B-Pi-/​122284870420|UPS HAT for the Pi]] to counteract effects of power failure. 
 +  * A backplane for easy and stable connecting of Pi and iC880A; https://​github.com/​gonzalocasas/​ic880a-backplane 
 + 
 +==== Other options ==== 
 + 
 +A more open alternative to the closed iC880A is to contribute to development of existing similar concentrators with open schematics such as [[https://​github.com/​will127534/​LoRa-concentrator|this one for 433 MHz (US)]] ([[https://​hackaday.io/​project/​13373-lora-concentrator|Hackster project]]). ​  
 + 
 +The TTN [[https://​www.thethingsnetwork.org/​labs/​|Labs]] and [[https://​www.thethingsnetwork.org/​wiki|wiki]] contains loads of possible node and gateway constructions.

   * The labs' physical location is near ideal for coverage of the central parts of Esbjerg and we have a nice 3 story building to put an antenna on top of. However, we probably need the building owner'​s (which is [[http://​www.tobakken.dk/​images/​PDF/​Vedtaegter.pdf|Esbjerg Kommune]]) permission to install antennas on the roof. Have a feeling that might prove to be non-trivial.   * The labs' physical location is near ideal for coverage of the central parts of Esbjerg and we have a nice 3 story building to put an antenna on top of.
