I am working on designing a solution for a solar powered LTE to WiFi bridge whose purpose is to sit on a mountain top and provide Internet connectivity to a remote business far from any road or infrastructure. This mountain lodge does not have any LTE coverage today, but there are high speed LTE on a mountain top with line of sight 2 km away.
The obvious solution would have been a industrial LTE modem connected to a PtP wireless solution powered by a decent sized solar panel.
The problem is however that this location does not have that much sunlight and ideally this relay station would be as small as possible as to blend in with the environment around it. A low power LTE device consumes about 2-3 W, but adding a PtP device adds about 5 W on top of that.
I am therefore looking into if there are LTE devices with integrated PtP wireless options ?
Could potentially it be an option to use a high gain directional panel antenna on a RUT240 forexample? If a 18 dbi antenna at each end would give sufficient range, then I could potentially be looking at a average power consumption of less than 3 W for the entire station. Potentially lasting for weeks without sunlight on a 200 Ah battery.
Are there other options that could make more sense ?
