1. What is the frequency range of the 2.4GHz WiFi band?

The 2.4GHz WiFi band operates within the frequency range of 2.412 GHz to 2.472 GHz (or up to 2.4835 GHz in some regions) and is divided into 13 channels (though channel 14 is rarely used).

2. What are the advantages of 2.4GHz WiFi?

Wider coverage and better wall penetration: Its lower frequency allows signals to travel farther and penetrate obstacles like walls more effectively than higher frequencies.

Strong compatibility: It supports older devices (e.g., IoT gadgets like smart bulbs and cameras) and is widely adopted.

3. What are its limitations?

Slower speeds: Theoretical maximum speeds range from 150 Mbps to 574 Mbps (depending on channel width and MIMO configurations), but real-world speeds are often lower due to interference.

High interference risk: This band is crowded with devices like Bluetooth gadgets, microwaves, and other WiFi networks, leading to potential congestion and stability issues.

4. How can I improve 2.4GHz WiFi performance?

Use channels 1, 6, or 11 to minimize overlap with neighboring networks.

Reduce the channel bandwidth to 20MHz (instead of 40MHz) for better stability in congested areas.

Position the router centrally and avoid physical obstructions.

5. Is 2.4GHz WiFi still relevant?

Yes! It remains ideal for smart home devices and environments where broad coverage is prioritized over high speed. For activities like gaming or 4K streaming, 5GHz or 6GHz bands are better suited.
