Overview of Bluetooth Technology    best in ear earphones

Bluetooth is an open wireless communication standard whose original intention was to replace cables with invisible cables. The aim and purpose is to reshape the way people live by staying connected, not relying on cables, rejecting plugs. It will replace the current various cable connection schemes. Through a unified short-range wireless link, various information devices can pass through walls or briefcases to achieve convenient, fast, flexible, safe, low-cost and low-power voice and data communication. www.bjbjaudio.com

It promotes and expands the application scope of wireless communication, enabling various data and voice devices in the network to interconnect and interoperate, thereby realizing fast and flexible data and voice communication in personal areas. The purpose of "Bluetooth" technology is to realize seamless resource sharing within a short distance between specific mobile phones, portable computers and hosts of various portable communication devices. www.bjbjaudio.com  

As an open global standard for wireless data and voice communication, Bluetooth technology is based on low-cost short-range wireless connections to establish a special connection for fixed and mobile device communication environments to complete short-range wireless transmission of data information. Its essence is to establish a common radio air interface (RadioAirInterface) and an open standard for its control software, so that communication and computer can be further combined, so that different manufacturers can produce   
of portable equipment without a wire or cable connection,
It can have interoperability and interoperability in a short range. www.bjbjaudio.com  

Specifically, the role of "Bluetooth" technology is to simplify the communication between small network devices (such as mobile PCs, PDAs, cell phones) and between these devices and the Internet, eliminating the need for cordless or mobile phones, modems, headsets to send Add wires, cables and connectors between receivers, PDAs, computers, printers, slide projectors, local area networks, etc. www.bjbjaudio.com

In addition, Bluetooth technology also provides a common interface for existing digital networks and peripherals to form a group of personal ad hoc connected devices away from fixed networks. The Bluetooth technology uses the 2.45GHz ISM (Industry, Science, and Medicine) frequency band that is globally available and can be used without application. If the center frequency is 2.45GHz, a maximum of 79 channels with a bandwidth of 1MHz can be established in this frequency band. Its transceiver adopts Frequency Hopping Spread Spectrum (Frequency Hopping Spread Spectrum) technology to conduct frequency hopping communication at a rate of 1600 hops per second on the 2.45GHz ISM frequency band. www.bjbjaudio.com
