Mobile Data Demand Drives Backhaul Evolution

Operators agree on four key goals:1. I will stop spending in a dead end

2. I will find a way to utilise cheaper transport3. I will use statistical gains

to reduce my costs even further

4. I will find a way of converging 3G service with my other networks (without compromising services)
