After months of revision, the Bluetooth Technology Alliance (BSIG) now officially launched Bluetooth 5.

In addition to removing the suffix ". 0" in naming, Bluetooth 5 also brings many new features. In terms of specifications, the bandwidth of Bluetooth 5 has been increased to 2Mbps, and the transmission distance has also been increased by four times. The theoretical effective transmission distance is 300 meters, which can send 255 Byte packets, reducing the loss of transmission efficiency caused by interference in the 2.4GHz frequency band.

New features

1. Bluetooth 5 will be faster

In theory, it will be twice as fast as Bluetooth 4. X BLE, up to 2Mbps. Although it may not reach the theoretical value in fact, it will certainly be much faster than Bluetooth 4. X.

2. Wider reception range

Similarly, the theoretical reception range can reach up to 200 meters. When connecting wireless devices such as Bluetooth speakers, they will no longer be limited.

3. More accurate positioning

Bluetooth 5 supports indoor positioning navigation, even if you are in the mall, you can also accurately locate your location.

4. Prepare for the coming of the Internet of Things era

With the improvement of low power consumption, transmission speed and reception range, smart home will usher in the next wave.

5. New hardware support is required

A new chip is required to support Bluetooth 5. Although it can also be compatible with old devices, it cannot obtain the above improved performance. It is expected that a large number of new devices supporting Bluetooth 5 will be launched in 2017.
