while this forum is certain for open source LibreRouter, but it came to my mind to share this topic too. while librerouter is very useful in its applications, just wanted to say TV white space antenna is also very good and useful for long range with lower power consumption and high bandwidth. have you worked on this type of LPWAN technology as well?
Hi Mahmoud ! Welcome to the forum!
Indeed, TV white space is a very important topic and supporting and developing a TVWS board for the LibreRouter is in our RoadMap. Elektra did a working prototype (https://wiki.freifunk.net/MABB:TVWS in german) and started a MIMO prototype (here is the design https://github.com/elektra42/Freifunk-Libremesh-TVWS-Converter).
To expand a bit more. The idea is to use do a transverter board that converts a mPCIEe 802.11n radio into a TVWS doing the frequency translation.
