PFsense on a PC Engines APU is a good alternative for now if anyone is looking for something today.
General purpose hardware can always be adapted if you have the skills and the money to spend on your project. We work from the global south with global south realities in mind.
A LibreRouter node, with outdoor casing, three sector antennas, GPS module, pigtails, etc. will cost around $150 and will be ready to deploy by non-expert users following simple instructions.
More so to start a discussion on what can be done in the home today instead of a completely proprietary router.
I will be keeping my eye on this project for WWAN or site to site applications.
Thank you for the good work.
