AT&T is no different to most incumbent operators in its outlook for using bonded copper for mobile backhaul. In his comments, Yiannis stresses the importance of “very low latency, jitter and packet loss” in the backhaul network. He also states that while AT&T will primarily drive fiber and microwave into the backhaul network to support growing data traffic, he still leaves the door open to the possibility of a “small percentage” of cell sites being supported by bonded copper in the future. With one or two exceptions, you would be hard pushed to find many leading mobile operators around the world that have a substantially different view from that. Of the small handful of operators I’m aware of that may see a large share of their cell sites supported by bonded copper backhaul, most have it down as an option if they move forward with large femtocell deployments. Say what you like about AT&T, but there is nothing unusual about their outlook here.
