A VTU or conference room implemented using wireless components must be protected from external control or compromise.

Conference room VTC systems, and particularly large ones, can require multiple microphones, cameras, and displays along with AV control systems. These systems typically require a significant amount of wiring. This can be a problem when retrofitting a well-appointed conference room without damaging the room’s walls, ceilings, furniture, and finishes. As a result, conference room VTC systems as well as other VTC endpoint systems can utilize various wireless communication technologies to interconnect its microphones, cameras, speakers, desktop audio conferencing units, and displays to the VTC CODEC and control panels to the AV control system and CODEC. The wireless communications technologies used are 802.11, Bluetooth, standard radio (cordless telephone and wireless microphone frequencies/technology) as well as infrared.

The use of wireless technologies to implement a conference room in a DoD facility could pose an eavesdropping vulnerability to VTC conferences and other meetings held in the facility. This could place sensitive or classified DoD information at risk. To mitigate this, all audio, video, white boarding, and data sharing communications within the conference room system must be encrypted. Furthermore, those technologies covered by the Wireless STIG and other DoD wireless policies, must be in compliance with them.
