Small cells remain the best solution for coverage and capacity

Physics necessitates the use of:

1.  Converged use of licensed and unlicensed spectrum (Wi-Fi)

2.  Improved spectral efficiency (LTE)

3.  Spatial efficiency (small cells + HetNet)

Heterogeneous Networks Why pursue multi-vendor over mono-vendor

Christenson’s “Innovator’s Dilemma” – the status quo is often fiercely justified for the purpose of protecting a position

•  Avoid vendor lock-in

•  Leverage best of breed products

•  Take advantage of innovation at a lower cost

•  Utilize proven X2 interoperability (e.g., Small Cell Forum, ETSI, and Orange Labs PlugFest)
