This is a work in progress. I received the TTOG on 22 May 2019, and the last few parts for the RAK on the day before. So far it seems like TTOG is still in beta and the software is quite limited in features.
Both have metal enclosures and come with a bracket to allow it to be pole mounted. The RAK comes with all required antennas, while the TTOG does not come with a LoRa antenna.
|Ethernet||Waterproof connector at bottom of case.||Waterproof connector at bottom of case.|
|Solar panel input||none||Yes (optional)|
|Software||Ubuntu 14.04.1 LTS. Very limited feature set. Only Semtech UDP packet forwarder support.||OpenWRT based. Fully working with good reconnect logic for switching or bad connections.|
|GPS antenna||Bottom of case. Nice and small.||Bottom of case. Way too long, making installation difficult.|
|LTE antenna||One at bottom of case, so not MIMO.||Two at top of case.|
|WiFi antenna||none||One at top of case.|
|LoRa antenna||Top of case N connector. Does not come with an antenna.||Top of case. Comes with a very good 868MHz antenna.|
|Sim card slot||Standard Sim size. Can be accessed without opening the case. In an unused antenna connector at top. This might be a risk for water ingress if the slot cover is not secured properly.||Nano Sim size. Internal sim card slot.|
|Remote management of gateway||unknown||The web interface can be accessed from the internet if the gateway has a public IP address.|
|Pole mount bracket||1 degree of freedom.||2 degrees of freedom, but feels a little flimsy. I won’t use this on a high site with a lot of wind.|
The TTOG comes in a very nice and compact outdoor enclosure, but it has less features than the RAK. The TTOG’s antennas - which it has less of - are spread out well around the case. The RAK7249 has too many antennas too close together that might interfere. Also the RAK’s antennas are unnecessary large. The latter makes installation difficult.
The RAK7249 comes with very stable and feature rich firmware. The TTOG’s firmware allows it to be configured for a Semtech UDP gateway server, ethernet and LTE.
For remote inaccessible sites neither of these two gateways provide a reliable remote management interface like we are used to with Resin.io (BalenaCloud).
Both gateways come with pole mount brackets which allows it to be tilted or rotated in different directions when its mounted. This is however a weakness in the design and in places with a lot of wind this bracket might break, or at least let the gateway sway around.
