Yealink explores Yealink's simplified explanations of common business communication terms regarding the application of three major communication devices, IP Phones, Video Conferencing Equipment and Headsets running on Microsoft, Zoom and other systems, in business work.

Full Duplex refers to a transmission method in which both communicating parties can perform sending and receiving operations at the same time when the sending and receiving of data are split and transmitted by two different transmission lines. In full-duplex mode, each end of the communication system is equipped with a transmitter and a receiver, so data can be controlled to be transmitted in both directions at the same time. Full-duplex mode does not require direction switching, so there is no time delay caused by switching operations, which is very beneficial for interactive applications that cannot have time delays (such as remote monitoring and control systems). For example, among communication products, walkie-talkies are a typical example of half-duplex; telephones are a full-duplex application.

Although full-duplex is convenient, since it sends and receives voice at the same time, it will cause an unavoidable big problem - echo. Because both sides of the two-way intercom speak at the same time, the other party's voice is transmitted to the microphone through the speaker, causing echo crosstalk, which affects normal calls. Therefore, if you want to realize the full-duplex voice intercom function, you must first overcome the problem of eliminating echo.

Enterprise-level audio quality is the guarantee for efficient meetings. As one of the few manufacturers with independent intellectual property rights in communications audio processing technology, Yealink Networks helps customers continuously improve their voice conferencing experience through continuous optimization and innovation of audio technology. Yealink Video Conference System VC800 has a built-in 24-point MCU and adopts a three-microphone array design to support 360° omnidirectional sound pickup, 6-meter full-duplex high-quality sound pickup, and is equipped with 2 expansion microphones to extend the sound pickup distance to ensure high-quality sound pickup. Meeting effect: Yealink intelligent noise cancellation technology intelligently eliminates non-speech sounds such as keyboard and mouse clicks, effectively avoiding noise interference and making communication more focused.
