1. At present, the distance of the civil version of Bluetooth is between 8-30m, which is an ideal state. In reality, there will be much interference of wireless signals and wall blocks, so it will generally be about 10m, while the other Bluetooth transmission suitable for business and industry will be about 80-100m. However, the volume and power of the transmitting and receiving antenna are large, and there are also high manufacturing costs and power consumption, Generally, it is not suitable for the use of personal communication products, and it will be used for special commercial purposes.

2. The longest distance of powerclass2 with Bluetooth technology is 10 meters. This is also the technology used by most mobile phones and mobile devices now; Using the upgraded Bluetooth technology, powerclass1 increases the longest distance to 100 meters; Of course, the furthest is only theory. Generally speaking, taking the longest distance of 10 meters as an example, there is no big obstacle between the mobile phone and the Bluetooth headset, and the transmission quality is very good within 7 meters. If it is more than 8 meters, the transmission data will be lost or frequently disconnected, while if it is more than 10 meters, the connection between Bluetooth devices will be lost.

3. The distance of Bluetooth function connection depends on: the distance of Bluetooth connection depends on the power and category, but the effective connection distance will vary in practical applications. The standard of Bluetooth is ieee802.15, which works in the 2.4GHz band with a bandwidth of 1mb/s; The core specification of Bluetooth stipulates the connection distance, but the technical connection distance is determined by the application and is infinite. The manufacturer can adjust the connection distance according to the actual application.
