Realistic 5G network scenario showing low utilization at a base station with uneven user performance, illustrating the myth of unused capacity in telecom networks.

THE MYTH OF “UNUSED CAPACITY” IN 5G NETWORKS

“This cell has low utilization… so there’s plenty of capacity.” Sounds logical. But it’s often misleading. Because capacity is not just about utilization. It’s about usability.

Low average load can hide peak congestion periods where users experience poor throughput.
Radio conditions vary across the cell, meaning not all resources are equally usable.
Control channels, signaling, and overhead consume part of the capacity.
Resource fragmentation reduces effective throughput even when PRBs are available.

So yes… Capacity may exist on paper. But not always in practice. This is where many optimization decisions go wrong. Because we assume unused resources = available performance. And that’s not always true. Real capacity is contextual. Not theoretical.

What’s your view? Have you seen cases where “low load” cells still deliver poor user experience?
