1What Is Wireless Networking and Why Does It Matter
IEEE 802.11 is the family of standards that defines Wi-Fi. Amendments such as 802.11n, ac and ax (Wi-Fi 4, 5 and 6) raise speed, capacity and efficiency over time.
What is the difference between 2.4 GHz and 5 GHz?
The 2.4 GHz band travels further and passes through walls better but is crowded and slower. The 5 GHz band offers more channels and speed over shorter distances.
Why do RF basics matter for security?
Radio signals travel beyond walls, so anyone nearby can listen or interfere. Understanding RF helps you plan coverage and secure wireless. This free beginner Codelivly room covers the fundamentals.
