Bluetooth technology changes to optimize the TWS headset user experience

As early as 2016, the Bluetooth Special Interest Group (SIG) officially launched the fifth generation of Bluetooth technology. The Bluetooth 5.0 standard has not only increased the communication speed by 2 times, but also increased the communication distance by 4 times. The capacity has increased by 8 times, and the underlying functions of the IoT Internet of Things have also been optimized. This provides a solution with low power consumption and high efficiency for the wireless communication of the Internet of Things. The introduction of chips supporting Bluetooth 5.0 technology is helpful to solve the key delay, stability, power consumption and other problems of TWS headphones. The application of Bluetooth 5.0 standard on TWS headphones has many advantages over previous generations:

(1) Higher bandwidth: Compared with the previous Bluetooth 4.2, the bandwidth of Bluetooth 5.0 has been increased from 1Mbps to 2Mbps, and the actual transmission speed is 1.7 times that of Bluetooth 4.2, which greatly shortens the synchronization between the headset and the mobile terminal and between the main and auxiliary headsets The response speed of TWS makes the delay problem of TWS headphones better solved.

(2) Higher power: The transmission power of Bluetooth 5.0 is upgraded from 10dBM to 20dBM, which reduces the interference between wireless devices in the crowded 2.4Ghz frequency band. At the same time, SIG also stated that Bluetooth 5.0 will be more effective in avoiding signal blocking in dense spaces, making it possible to maintain a stable connection even in public areas with complex signals.

(3) Lower power consumption: With greater data throughput and more stable signals, TWS headsets have improved power control with Bluetooth 5.0 technology, allowing headset manufacturers to add more features such as noise reduction to TWS headsets , Voice assistant and other functions and configuration, under the guarantee of ideal battery life and reliable stability, make the TWS headset have a good experience.

On the basis of Bluetooth 5.0, on January 29, 2019, the Bluetooth Technology Alliance officially announced the Bluetooth 5.1 standard. The new standard can improve the accuracy of indoor positioning. Without wifi assistance, it can achieve positioning functions with accuracy close to the centimeter level, which is conducive to Recover lost of wearable devices such as TWS headphones. In addition, the Bluetooth 5.1 standard also optimizes GATT (General Attribute Configuration File) to improve pairing and communication speed and optimize the connection experience. If Bluetooth 5.0 is a leap forward compared to the 4.2 standard, then 5.1 is an improvement on the basis of the 5.0 standard, which further optimizes the wireless experience of the TWS headset.
