Short story. In the engineering field but this is outside my lane! In an area with poor cell coverage but not exactly. I am 5mi from the tower and if I stand out on the dirt road, I have line of sight and can access the Sprint band 41 (2.5Ghz) with download tested at 250mb/s. The issue comes in that I am about 500ft off the main road in which band 41 is totally inaccessible and reverts to bands 25 and 26 with poor signal. I have tested up in the scissor lift and I certainly get signal if I am high enough. It is simply a matter of repeating the signal. Due to this drama, Sprint is sending me a SIM to access the 600mhz band which should cover better but probably poor data speed. Originally I figured I could just amp and rebroadcast the 2.5ghz until I realized I could not get an amp for that? Some FCC rule because it is too close to the typical 2.4ghz wifi bands? I have a few options I guess but because I can clearly see my dirt road 500ft away, I considered a passive double yagi to rebroadcast and turn the signal 90* over to me. But I have had conflicting advice on that, or if I can do a simple booster closer to the road and cover the property better? I am told "it does not work like that". Even if I get stuck using the 600mhz, I am sure it won't be well covered either because I am a bit low in elevation. I don't want to get stuck just having service inside a structure because it becomes a safety matter to have outdoor cell service on a farm.
