9. QoS Management

QoS Management sets rules so critical traffic gets through cleanly while everything else waits its turn. On wireless, airtime is gold—spend it wisely.

Why It's Important

Voice, video, control traffic—some packets can’t be late. QoS keeps them honest when the network gets busy.

How to Improve QoS Management Skills

Prioritize with intent, then verify:

1. Measure first: Baseline latency, jitter, loss, and airtime usage. Know your bottlenecks.

2. Classify traffic: Map apps to DSCP and WMM access categories; be explicit.

3. Shape and police: Rate‑limit noncritical flows; reserve bandwidth for real‑time traffic.

4. Tune WLAN settings: Use 802.11e/WMM correctly; avoid SSID sprawl; minimize management overhead.

5. Engineer roaming: Fast transitions (802.11r/k/v) keep real‑time sessions intact.

10. Spectrum Analysis

Spectrum analysis reveals what the air is doing—signals, noise, interference sources, and how they change over time. It’s your RF truth serum.

Why It's Important

Without it, you’re guessing. With it, you can spot hidden interferers, pick cleaner channels, and prove whether the issue is RF or higher‑layer.

How to Improve Spectrum Analysis Skills

Technique matters as much as tools:

1. Keep instruments calibrated: Accuracy starts with trustworthy gear.

2. Use advanced features: Waterfalls, peak hold, markers, triggers—see both snapshots and trends.

3. Survey at the right times: Measure during real peak periods; interference is often seasonal or scheduled.

4. Account for environment: Weather, doors, elevators, and people change RF behavior. Note conditions.

5. Correlate with network data: Align RF events with logs and client metrics to pinpoint root causes.

The spectrum tells a story. Read it carefully, then write a better ending.
