Loosely related but a number of rest homes have recently been fitted out with RCG's iConn in-building coverage solution for all of the reasons listed above (dense walls, RF blocked, etc.). Basically it works exactly the same as RCG's typical rural coverage works (i.e. you have full bars on all 3 main carriers) with the only real difference being it's designed to go in buildings (like rest homes) as opposed to just in remote rural locations. Could be worth suggesting the facility look into getting it installed if it's an issue for many residents. I have no idea of the cost.
