The 2.4 GHz Band is a frequency range commonly used for wireless communication, including Wi-Fi and Bluetooth. It operates between 2.4 and 2.4835 GHz and is popular due to its ability to cover longer distances and penetrate walls better than higher frequency bands. However, the 2.4 GHz Band is often crowded, as many devices, such as microwaves and cordless phones, also operate within this range. This congestion can lead to interference, affecting the performance and speed of wireless connections. Users may need to consider this when setting up their networks or devices.
