This document discusses the intersection between LTE and femtocells. It argues that while LTE is moving forward without femtocells in terms of public capacity needs, the residential use case for femtocells is more complicated due to issues like home WiFi networks, coverage versus capacity needs, and the capabilities of 3G technologies. It concludes that for femtocells to succeed in the LTE era will require subsidies, applications that drive data usage, a clearer LTE narrative beyond just network capacity, the development of multi-standard femtocells, and continued evangelism efforts.

9. The Capabilities of HSPA+
Just your average Twitter conversation…
 @pnjarich: So, the iPhone 4S tops out at HSPA+ 14.4. Not
even 21 Mbps?
 @GlennF: @pnjarich Why would anyone need more than
14.4 Mbps on a phone? Who cares?
 @pnjarich: @GlennF Operators, that’s who. When you’re
trying to maximize network capacity, HSPA+ 21 (or, better
yet, 42) matters.
 @GlennF: @pnjarich Understood.
