Feedback for an engineering project

Hello r/networking, I'm a first year engineering student who's been assigned a group project in which we have to create a design that will improve mobile data access in rural Australia (well that was one option anyway). Nobody in my group had any prior knowledge about networking systems at all but we have been studying it a lot over the past month. However, we are still very inexperienced so I thought I would see what you guys think of our design.

Our system will be using antennas and cellular repeaters. We wanted to use high gain dish antennas and operate on a 3G network (using a 900MHz frequency) to compromise between signal quality and signal range. The antennas would be mounted on large poles and the system would be powered primarily through solar power. The large problem we overlooked was that we thought the range of the design was limited by the cell tower's range, and only later we realised that it would be limited by the antenna's range. We thought the design could work over distances of 80km, it turns out it would only work over 8km. So we thought maybe we could turn each house into its own sort of "mini base station". The houses would form a "chain" where the signal from one house is passed onto the next house and so on until it reaches the real base station, from which it can connect to the rest of the network. I'm sure this is an absolutely horrible idea so I thought I'd get some input from people who know what they're talking about!

Once again, we have almost no prior experience with networking or even with engineering for that matter so please excuse my ignorance (and our unit coordinator is a bit useless). And a quick disclaimer: the assignment rubric isn't actually focussed on the design, its more focussed on our method, so we aren't cheating by posting this, its purely for personal reasons.

Thank you!
