The wireless conference discussion system can be composed of a conference system control host, a wireless conference unit, a signal transceiver, a cable connecting the host and the signal transceiver, and a conference management software system.
Paperless conference system
The paperless conference system has gradually become an important development direction of conference system technology because of its ease of installation and movement, ease of use and maintenance, and no impact on buildings. At present, there are two main types of paperless conference systems, one is a paperless conference system based on radio frequency (radio wave) technology, and the other is an infrared paperless conference system. The paperless conference system based on RF technology using analog audio transmission is vulnerable to external malicious interference and eavesdropping, and requires radio frequency license; while the analog infrared paperless conference system is not satisfactory in terms of sound quality, and its frequency response is generally It is 100Hz~4kHz, which is only equivalent to the sound quality level of ordinary telephones. To this end, a digital infrared paperless conference system has recently been developed.

The infrared conference unit with conference discussion function usually includes a microphone, a microphone switch button, and components such as a speaker and a battery. The infrared conference discussion unit receives the audio signal and the control signal broadcasted by the infrared conference system host in the form of infrared light, and sends the control signal to the infrared conference system host in the form of infrared light. When the microphone is turned on, the infrared conference discussion unit simultaneously sends digital audio signals to the infrared conference system host in the form of infrared light. Any number of infrared conference discussion units can be used throughout the system, but only up to four infrared conference discussion units can be turned on at the same time.
