A multi-tenanted building and a strong cell-signal: two opposite sides of a coin that never meet. Haven’t we all been there, and been there so often? After all, the average American is said to spend 93% of their lives indoors. Of which, only 6% of that is spent in automobiles, and the 87% indoors. That ‘indoors’ comprises our residences, apartments, office towers, corporate buildings, industrial premises, factories, shopping centers, hotels and more. All these places are indoor sites that seem to have everything but In-Building Cellular coverages. When we’re indoors and have a call to make or take, we’re constantly in the hunt for the nearest window so we can pick up on the residual leftovers of the carrier signals. Pathetic, to say the least.
