I lean toward the LTE approach, as satellite tends to be more expensive and satellite networks always get over-sold and slow down, while the capacity of terrestrial LTE is expanding.
The project can be divided into four parts. Each one is likely going to be a separate piece of equipment.
- Receiving the LTE service
- Link from the LTE receiver site to the village
- Central router, with bandwidth control
- User access via WiFi
For the LTE link, a unitized device with integral directional antenna intended for outdoor use would be better than cobbling together something with separate antennas and an indoor router mounted in some sort of weatherproof box. The NR7101 is nice but it is Europe bands and has become expensive as the supply of used ones left by a defunct service operator has been used up. I use the Mikrotik LHG-R-LTE6 it suits my usage but I'm not saying it is the best thing out there. It is not expensive and doesn't use a lot of DC power, but it is not (yet) OpenWrt and the dish has basically nil gain on the sub 1 GHz bands, which is the physics of a dish that size. They also make the LDF-LTE to retrofit to any old satellite dish. This will require some fabrication since the mount of a typical satellite dish is not made to aim the beam to zero elevation needed for terrestrial links.
For part 2 I would use 5 GHz CPE equipment. The link distance of 1.5 km is well suited for that if the path is not obstructed. If there is unavoidable multiple obstructions you could consider fiber optic cable.
Part 3 is where OpenWrt shines as you can do things like multiple networks with limited bandwidth. LTE speeds don't require particularly high performance hardware. MT7621 would be sufficient.
And for part 4 you're very likely going to use a mesh as this is a good way to distribute around a small village. This would likely be indoor routers running OpenWrt placed inside houses.
