Here at CTIA a common theme expounded in most meetings is the need to drive bandwidth-hungry mobile services. Whether this is motivated by the desire to supress device price erosion orby the notion of connecting more bandwidth-hungry services with higher ARPUs, this is flawed.

What the industry really needs to focus on is lowering the cost per bit per hertz. This can only be serviced by a rapid transition in core network and backhual architectures coupled with innovative content caching and routing solutions. A failure to sort backhual and core network dimensioning will cripple 4G. We will have smart, capable devices running on archaic underprovisioned networks. Most importantly - a correct dimensioning of the network will be crucial in reducing the cost of 4G services of the future.
