Re: Backhaul Burnout...

On 3G you can have full signal bars and no throughput because the air interface is congested - most handsets only look at signal strength and ignore signal to noise ratio.

Similarly on 2G, the handsets measure received power of the broadcast channels and show bars based on that. But a strong signal on the broadcast channel doesn't mean there's any traffic channel available.
