In the paperless conference system (paperless conference discussion system), the system transmission electrical performance requirements from the conference unit microphone input to the conference system control host or the microphone control device output port shall comply with the relevant regulations.

Paperless Conference System (paperless conference discussion system)
(1) It is not appropriate to use a simulated paperless conference system (paperless conference discussion system) when the number of microphones is greater than 100.
(2) When the maximum distance from the conference unit to the conference system control host is greater than 50m, it is not appropriate to use the analog wired paperless conference system (paperless conference discussion system).
(3) The conference unit and conference microphone should have anti-radio frequency interference capability. When using the RF wireless paperless conference system (paperless conference discussion system), it is necessary to ensure that there is no RF equipment in the same or similar frequency band near the site.
(4) When there is confidentiality and anti-malware interference requirements for the meeting, it is advisable to use a wired paperless conference system (paperless conference discussion system) or a wireless paperless conference system (paperless conference discussion system). It is said that the wired paperless conference system (paperless conference discussion system) has good confidentiality and can prevent malicious interference.
The wireless paperless conference system (paperless conference discussion system) is divided into infrared and radio frequency. In the infrared wireless paperless conference system (paperless conference discussion system), the signal is transmitted by infrared light. When the meeting is closed, the door and window are closed, and the blackout curtains are added on the transparent door and window. Isolation from the outside world can serve as a meeting confidentiality and prevent malicious interference.
For RF wireless paperless conference systems (paperless conference discussion systems), RF electromagnetic waves are used and signals can penetrate walls. Therefore, in order to prevent someone from using the same equipment as the system to eavesdrop outside the venue, it is necessary to strictly manage the equipment and related technical personnel. Secondly, it is necessary to avoid the radio equipment working in the same or similar frequency band as the system in the vicinity of the venue, or to use the same or similar frequency band of the system for malicious interference.
(5) When designing a wireless paperless conference system (paperless conference discussion system), the receiving distance of the signal transceiver and the conference unit should be considered. The signal transceiver can be mounted in a ceiling, wall or flow manner.
(6) When designing an infrared paperless conference system (paperless conference discussion system), the venue should not use a plasma display. If you must use a plasma display, avoid using an infrared conference unit and a signal infrared transceiver within 3m of the plasma display, or install an infrared filter on the plasma display screen.
