Episode 36 — Wireless Interfaces: Bluetooth, NFC, Wi-Fi Standards

August 25, 2025 · 13 min

Show notes

Wireless connectivity is everywhere, and the CompTIA IT Fundamentals (ITF+) certification exam expects you to know the key technologies behind it. This episode covers Bluetooth, NFC, and Wi-Fi, including how each operates, their common use cases, and the security considerations associated with them.

We’ll also compare different Wi-Fi standards, such as 802.11n, 802.11ac, and 802.11ax, to show how they differ in speed, range, and compatibility. This prepares you to answer questions on wireless interface selection, configuration, and troubleshooting. Produced by BareMetalCyber.com.
