Delivering 26x increase in Supply
•  Service usage growing unchecked
•  Macrocell capacity growth cannot
keep up with demand
•  Licensed spectrum availability not
growing to meet demand
•  Smaller Cells are needed to scale
supply efficiently & economically
•  Licensed and Unlicensed Spectrum
will need to be exploited
