Rooftops are becoming increasingly relevant with the advent of 5G deployment. 5G coverage is line of site so a large number of rooftop sites will be needed for complete coverage.
In order for the "internet of things" to effectively develop, the number of micro-cell sites will need to grow exponentially. Rooftops will be a primary location for facilitating this equipment. The devices will be small, unobtrusive, and run on 110V power. The EMF emissions are very low, similar to other electric devices currently in an average home.
The rooftop deployments will enhance the owners' own digital experience along with the neighbors around them.
