Bluetooth is a general-purpose radio communication port with a new rate of 245GHz, which can establish a wireless connection and short-range communication between various portable devices through a special network. In a piconet, each unit can communicate with every other unit at the same time. Also, each cell can belong to several piconets at the same time. Bluetooth technology was first developed by Ericsson and has now been supported by Nokia, IBM, Toshiba Intel and many other related manufacturers. Its purpose is to eliminate the need for additional wires, cables and connectors between cordless or mobile phones, modems, headsets: PDAs, computer printers, slide projectors and local area networks, etc. Moreover, this technology can be extended to those completely different new devices. bjbjaudio.com

The technical characteristics of Bluetooth, the character rate of 1M symbols per second is transmitted, and the maximum effective bandwidth of the channel is fully utilized to avoid interference. The variable power output minimizes interference and adopts short data packet transmission enhancement. Anti-jamming capability, fast acknowledgment allows additional low-rate codes to be sent onto the link, continuously variable slope delta-modulated speech coding works well at high bit error rates, flexible packet types support a variety of Application: The radio air interface minimizes power consumption. bjbjaudio.com    <a style="opacity:0.0;color:#ffffff">tws earbuds youtube</a>

In standby mode, the current consumption of Bluetooth is only 03mA, which can prolong the service life of the power supply device: the current consumption is a maximum of 30mA during data transmission, and the current consumption is lower when suspending work or transmitting data at a low speed. Each small, high-performance and integrated radio transceiver has a unique 48-bit address specified by the IEEE802 standard, and the open 2.45GHzISM free frequency band can be used freely worldwide. 10km is the communication range suitable for the mobile communication market and commercial users. The total rate is 1Mbit/s, and it is planned that next-generation products will reach 2Mbit/s point-to-point connections allowing a maximum data transfer rate of 721kbit/s. bjbjaudio.com    <a style="opacity:0.0;color:#ffffff">tws earbuds youtube</a>

Known as the "engine driving the new economy", Bluetooth technology, its English name is Bluetooth, is a short-range wireless communication technology standard jointly formulated by five companies including Intel, Nokia and Toshiba in May 1985. Its purpose is to achieve The maximum data transmission rate is 1Mbps (the effective transmission rate is 721kbps), and the maximum transmission distance is 10 meters for wireless communication. In July 1999, the BluetoothSIG (Bluetooth SpecialInterestingGroup, Bluetooth Special Interest Group) announced the official version of the Bluetooth specification. Bluetooth technology adopts an open technical standard, which has been widely recognized by the industry once it is launched, and products based on this standard have now appeared. At present, Bluetooth technology has become the most popular research and development direction in the field of short-range wireless data communication. More than 2,000 companies have announced their support and development of Bluetooth technology and related products. Bluetooth technology is a low-cost, low-power wireless access method, which has been widely used in information appliances, mobile communications, embedded application development and many other aspects. It conforms to the development trend of modern communication technology and applications, and its prospects will be endless Limited. bjbjaudio.com           <a style="opacity:0.0;color:#ffffff">tws earbuds youtube</a>
