Wireless Standards and Frequency Bands

Understanding the practical differences between common wireless frequency bands (range versus speed tradeoffs) helps a technician give genuinely useful configuration recommendations rather than generic advice.

Common Wireless Interference Sources

Physical obstructions, other wireless devices, and even household appliances can genuinely degrade wireless performance — a technician should recognize these as real, diagnosable causes.

Wireless Security Basics

Understanding current wireless security standards and why outdated ones are genuinely less secure helps a technician recommend appropriate configuration, not just “turn on some password.”

Optimizing Wireless Coverage

Access point placement, mesh network systems, and extenders each have genuine tradeoffs a technician should understand to recommend the right solution for a specific customer’s space.
