Advantages of Femtocells
• Coverage (Indoors where most usage is) – Overcomes building penetration problems
• Capacity/Throughput – High Sustained data rates
• Reduced need for CAPEX/OPEX Spend – Less Backhaul needed on Macro – Less Macro Base-station equipment needed
• Reduced Churn – Increased Stickiness

What has changed in Mobile Broadband?
• Paul Jacobs, CEO: “According to the results of our research, femtocells will possibly result in eight times higher throughput per user. In retrospect, an eight-times improvement is equivalent to that brought by the cell phone's shift from analog to digital. This is really an exciting fact.”
• Divergence between Revenue and Traffic
• Lower cost of mobile broadband delivery is the only answer
Jacobs says LTE will only provide a 10% spectrum efficiency improvement!
