The Road to Densification
Carriers have different starting points
Level Setting Demand HetNet Transformation
Dense Urban, Urban, Suburban, Rural
Macro, Micro, Pico
Projected demand requires capacity
Capacity & Speed triggers
Demand drives operators to acquire spectrum, densify and consider unlicensed
options
Yesterday – a mixture of solutions
Tomorrow – HetNet blending cellular, WiFi, and
customer experience
Natural transition to 5G

Small Cell term is being used to mean many things – the best representation of the term is below the
clutter and indoor
Network density is important for network capacity
• Operators will design their networks with a mix of macro and
small cells • Densification will occur from the
outside-in• A blend of macro-micro-pico below
the clutter will emerge
