Bluetooth 5.0 headset, where is the advantage?

1. Double the communication speed, from the current 1Mbit/s to 2Mbit/s.

2. The communication distance can be increased by up to 4 times. The linear communication distance can theoretically be up to 300 meters. This means that the Bluetooth signal messes up a room, the whole apartment is no problem, and even the whole small building is not a problem.

3. The stability of the Bluetooth connection has been improved. For example, the stability of the connection with devices such as sports headphones will be enhanced, and the probability of signal interruption will be reduced.

4. More accurate indoor positioning. In conjunction with Wi-Fi technology, it is theoretically possible to achieve positioning with an accuracy of less than 300 mm.

5. Improve performance with the same power consumption. Because of the low power design, no additional power is added.

6. Compatible with previous Bluetooth standards. That is to say, the old version of Bluetooth 4.2 and so on will be able to connect to devices equipped with Bluetooth 5.

7. Of course, since the new technology is based on new hardware, the old version cannot be upgraded to Bluetooth 5 by brushing firmware.

8. However, for Bluetooth headsets, the sound quality will not improve. Because Bluetooth 5 does not optimize the compression of the audio signal, subsequent improvements may be made in this regard.

9. The amount of Bluetooth broadcast data has been increased to 8 times. Bluetooth beacons and GPS positioning will get more data. Bluetooth beacons refer to information pushes based on locations near the interior, such as pushing discount coupons to customers entering the shoe store.

10. A mesh network similar to Beacon's letter has been added. The mesh network is a technology independently developed based on Bluetooth devices: Bluetooth devices can act as transponders of each other, like the Great Wall beacons, and the one-station station transmits signals farther and improves the signal transmission distance. . Compatible with Bluetooth 4 and 5 series protocols.

At present, many module manufacturers have also applied the Bluetooth 5.0 chip, and it will be used more widely in the future
