Before understanding the differences between USB and WiFi 2.4G, it's important to know what 2.4G is.
2.4G refers to the 2.4 GHz wireless frequency band, which is a commonly used range for wireless communication. It's mainly used in WiFi, Bluetooth, wireless mice and keyboards, wireless headsets, and other devices.
Strong signal penetration: Compared to 5GHz, 2.4G signals can better penetrate walls and obstacles, making it more suitable for long-distance transmission.
Longer transmission range: Under the same power, 2.4G can reach farther distances, which is ideal for larger spaces.
Widespread usage: Many wireless technologies like Bluetooth and WiFi operate on the 2.4G band, so interference is something to watch out for.
USB 2.4GHz: Mainly used for wireless connections to devices like mice, keyboards, and headsets. It uses the 2.4GHz band for low-latency, high-stability wireless transmission.
WiFi 2.4GHz: Used for internet connectivity. It also uses the 2.4GHz band to provide wireless networking over longer distances, though it's more prone to interference.
USB 2.4GHz: Uses RF (radio frequency) wireless technology to create a dedicated channel between the USB receiver and the device, resulting in a more stable connection that’s less affected by WiFi interference.
WiFi 2.4GHz: Supports multiple device connections, but too many devices on the same frequency can cause slower speeds and less stability.
USB 2.4GHz: Typically supports a range of about 5–10 meters. Since it uses a dedicated channel, interference is relatively low, making it great for gaming and other demanding uses.
WiFi 2.4GHz: Can reach over 30 meters, but is easily affected by other 2.4G devices, which can weaken the signal and reduce internet speed.
While USB 2.4GHz has a dedicated connection channel with lower chances of interference, having too many USB 2.4G devices nearby can still cause interference.
