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)
