The tower companies will let us know when 5G rollouts get real

Network densification is a key premise of 5G architecture. Once the rollouts of 5G networks begin in earnest, we should expect to see many more cell sites in urban areas across the world. How many more? That remains to see, but the count of small cells could be 10x of the number of macro base stations common in the 3G/4G era – or maybe even higher than that. Each one of these small cells will need a physical location, which must be purchased...
