1. Wide range of applications
Bluetooth technical specifications are unified globally, mobile phones, PDAs, wireless headsets, notebook computers, automobiles, medical equipment, computer peripherals and many other devices, as long as you have a Bluetooth adapter, you can easily connect to Bluetooth devices for data transmission or voice communication, widely popularized , good compatibility.

2. Easy to operate
Bluetooth technology is an instant technology, it does not require a fixed infrastructure, and it is easy to install and set up. It can be connected without cables.

3. Faster transmission speed
Compared with other methods such as infrared, the Bluetooth transmission protocol has obvious advantages in speed. The theoretical maximum speed of Bluetooth 4.0 reaches 24Mbps, and a faster speed can ensure higher sound quality, so that it has enough capacity to carry a higher bit rate. music.

4. Moderate transmission distance
The transmission distance of Bluetooth is generally within 10 meters, which is exactly the size of a room, and can transmit data across walls, which is very suitable for home use.
Although it has many advantages, because the Bluetooth transmission protocol, like other 2.4G devices, shares the signals of this frequency band, it will inevitably lead to mutual signal interference.
In addition, the Bluetooth protocol is not a free technology. Any manufacturer using this technology must pay a patent fee to the organization, and this part of the fee will also be reflected in the cost. In 2012, the price of Bluetooth audio equipment is still high. on ordinary products.
