Not sure how big the market will be for something like this; apart from, well, drug cartels in Mexico </joking>.

5G uses multiple bands, and the most useful, and highest throughput one, doesn't have a great range (high band, 24 GHz and up). So, perhaps you use 5G tech/devices but not use that, and instead focus on low band (600–900 MHz, few kilometers of range)? Would a mining company use this to oversee a large property? Would a large cattle operation benefit?
