THE HIDDEN IMPACT OF SCHEDULING ON USER THROUGHPUT

You can have great spectrum, strong signal, and still… low throughput.

Why? Because throughput is not just about radio conditions. It’s about decisions. Every millisecond, the scheduler decides who gets resources. And that decision defines performance.

• The scheduler balances multiple users, meaning resources are shared even under good radio conditions.
• Prioritization policies (fairness, QoS, latency) often reduce peak throughput for individual users.
• Short scheduling windows mean performance fluctuates constantly, even within seconds.
• Cell-edge users consume more resources, reducing overall spectral efficiency.

Here’s the reality: Two users in the same cell, same signal… Can experience completely different throughput. Not because of RF. But because of scheduling.

So the next time throughput drops… It might not be a coverage issue. It might be a decision-making issue.

What’s your view? Are we paying enough attention to scheduler behavior in optimization strategies?
