The 2.4G Wireless Digital Conference System is a fully digital conference system specifically designed to integrate wireless discussion, camera tracking, and other functions. A single conference host can connect up to 255 wireless digital conference units. The system operates in the ISM frequency band using 2.4G full digital frequency-hopping (DSSS) modulation communication technology, enabling seamless coexistence with WiFi and featuring exceptional anti-interference capabilities. It employs true wireless digital transceiver separation and adaptive frequency-hopping technology, along with forward error correction and retransmission mechanisms, ensuring data is never lost. With encryption protection, the system prevents eavesdropping and unauthorized access, safeguarding meeting privacy. The system supports three speech modes: "First-In-First-Out," "Normal Mode," and "Chairman Mode." It allows up to four units to be activated simultaneously, with the speaking count adjustable from 1 to 4, enabling effective order management during meetings.
This system requires no complex cable installations and can be flexibly configured to meet meeting requirements without the need for frequency applications. Its advanced 2.4G frequency-hopping modulation communication technology and digital transmission technology significantly reduce the impact of interference signals on system operation. The unique 2.4G transmission characteristics, combined with its robust digital transmission technology and comprehensive communication protocols, ensure maximum security for meeting content. The system meets the needs of both standard fixed-installation conference rooms and portable meeting setups, offering a high-reliability conference solution that is both convenient and efficient.
