A DCTN studio is expensive since you're essentially reengineering the room and buying the hardware. The prices haveactually dropped since then. The current plan is to have VIXS on each fleet flag ship. Conner, Kutch and Panuska are looking at desktop VTC that's coming on line at a much cheaper cost. Available bandwidth is a shipboard problem.
Video teleconferencing uses bandwidth the ship normally allocates for other things.
If they're conducting an afloat VIXS conference, they usually have to shut down some other tactical circuitry. It's a trade off. It involves prioritization. As different world wide situations develop, obtaining JCS approval for increased bandwidth becomes a battle for number one priority. Whether you're talking about VIXS, command and control or JOTS, there s always going to be more demand than there is availability.
