5G and LTE Mobility Signal in Lavington BC

Yes the tower north east of Lavington is behind a mountain. The other Telus tower is on top of a mountain east-southeast across the valley (map). That's give or take 10KM away with a direct line of site from Restoration Lands itself, and 12KM to Lavington. The towers west of Lavington in Vernon are small ones and have low broadcast power since they cover a smaller area so they wouldn't likely be providing service to Lavington.

Getting a tower of any kind built is not a simple or fast process. There are a lot of regulatory hurdles that have to be dealt with first. I'd be curious to see if a microcell is even possible at all and whether or not the cost is within reason. I'd hazard a guess that it'll be quite expensive.
