What is Bluetooth connection?
Bluetooth connection standard is integrated into most mobile devices such as Xiaomi 12T 128GB and even this laptop brings very useful features for users. The effective operating range of Bluetooth is about 10m with a data transfer speed of 1Mbps.
The operating principle of Bluetooth
When connected, Bluetooth will automatically find a compatible frequency to move to the device to be connected within the area to ensure stability during the connection process between devices. Regarding coverage range, Bluetooth has 3 different classes:
- Class 1: power 100mW with a coverage range of nearly 100m.
- Class 2: power 2.5mW, coverage range about 10m.
- Class 3: 1mW with a coverage range of about 5m.
And within Bluetooth itself is a collection of various protocols.
