Basic function speech intelligibility ensures the highest speech intelligibility at any time. The wireless conference device uses 2.4 GHz operating frequency band (no license required), with ultra-high signal-to-noise ratio and excellent antenna diversity, which can produce excellent sound effect. This means that the signal can be transmitted along a variety of propagation paths to ensure optimal signal reception. In addition, the system also has perfect protection function, which is not interfered by mobile phones and other devices using Bluetooth or microwave signals. Secure wireless communication means more security considerations need to be considered. Therefore, the DCN wireless system and conference devices adopt 128 bit AES encryption technology to prevent eavesdropping and unauthorized access.
