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)
