what is bluetooth low energy Bluetooth tws speakers

Bluetooth Low Energy is a brand new technology and the lowest power wireless technology currently available for design and use. As an extension of classic bluetooth, bluetooth low energy continues to use the bluetooth trademark and draws on many technologies of its parents. However, because the design goals and market areas are different from classic bluetooth, low energy bluetooth should be regarded as a different technologies. www.bjbjaudio.com

Classic Bluetooth was designed to unify computing and communication devices around the world, allowing mobile phones and laptops to connect to each other. However, it turns out that the most widespread application of Bluetooth is audio transmission, such as transmitting audio from a mobile phone to a Bluetooth headset. As the technology matures, more and more Bluetooth applications come into view, including stereo audio streaming, car download of e-books from mobile phones, wireless printing and file transfer. As each new application requires more bandwidth, faster and faster radios are being added to the Bluetooth system over time. The 10th version of Bluetooth is the basic rate (BasicRate BR), and the maximum physical layer data rate is 1Mbps (megabits per second); the 20th version is the Enhanced Data Rate (EDR ), and the physical layer data transmission rate is increased to 3Mbps; 30 The version introduces AlternativeMACEPHY (AMP, Alternate Radio Frequency Technology) using IEEE8802 11 to achieve a physical layer data rate of up to several hundred Mbps. www.bjbjaudio.com

Bluetooth Low Energy has taken a completely different direction: not just to increase the achievable data transfer rate, but to optimize for the lowest possible power consumption. This means that maybe you can't get very high transfer rates, but you can keep your connection open for hours or days. This choice is very interesting, obviously, most wired and wireless communication technologies are still increasing in speed. www.bjbjaudio.com

Classic Bluetooth doesn't really live up to their low power requirements for those coin cell battery powered devices. With that in mind, it's not hard to see why you chose a new direction. However, in fully considering the requirements related to low power consumption , it must also be considered that Bluetooth low energy should be designed to meet the requirements of very large-scale deployment for use in devices that have not been equipped with wireless technology to date. Achieving extreme scale requires extremely low cost. It is as if Radio Frequency Identification (RFID) obtains energy through a relatively expensive scanning device, but the cost of the tag itself is extremely low, resulting in a large number of deployments. www.bjbjaudio.com
