Verizon's Glenn Wellbrock, Director of Optical Transport Network Architecture, Design, and Planning, startled us at Light Reading's 5G Transport and the Edge event. Verizon is building 1,400 miles of fiber per month. Most talking heads think fiber is required.. But Glenn said:
"Don't underestimate wireless backhaul. We use that on about 10% of our sites and will increase it, possibly to as much as 20%".
Microwave latency is lower than fiber. Daisy Dunkley Clark of Ericsson wrote to me, "It is always the shortest path between point A and point B, and air is a faster medium than glass. A latency of much below 100 microseconds is fully feasible."
5 gigabit and 10-gigabit microwave are now standard products at a reasonable price.Add a comment
