Telepresence shatters communication barriers

From high-end suites to tabletop codecs, telepresence systems create a near face-to-face experience at increasingly affordable prices

Well before the current world financial crisis struck, organizations have sought inventive ways to engage in face-to-face meetings without the need to travel. Companies have turned to services such as Adobe Acrobat Connect Pro, Cisco WebEx, Citrix GoToMeeting, and Microsoft Live Meeting as a means for workers in multiple locations to share presentations and otherwise collaborate.

No question, these tools greatly reduce costly, productivity-sapping travel, with the added benefit of lowering a company's carbon footprint. Yet scratchy audio quality, out-of-sync slides, and tiny, Webcam-quality video often diminish these solutions' usefulness.

Similarly, more traditional videoconferencing systems (which have been around for decades) suffer from low utilization rates -- partially because of complicated, unreliable technology.

The door has now opened for telepresence solutions: a conferencing environment that seeks to mimic the in-person experience as much as possible. Several technologies make telepresence possible. High-definition video cameras and large, flat-panel monitors clearly display participants in life size. Optimized networks -- making use of QoS and even application-aware protocol acceleration -- help eliminate audio and video delay over long-distance and high-latency WANs. As such, participants can make eye contact with colleagues and immediately pick up on all-important visual cues -- such as how someone reacts to an offer. Moreover, operating the systems can be as simple as using a television remote control or telephone.

Something for everyone
In general, telepresence systems fall into three configurations. First, there are formal group setups, purpose-built rooms that accommodate four to eight participants. Here you'll find warm wall coverings, soft lighting, three or four wall-mounted monitors, and a conventional conference room seating arrangement. In use, it's as if remote participants are sitting across the table from you.

Second, you'll find small-to-midrange setups, which comprise a single monitor and one camera, suited for handling one to four users. This option works well in executive offices, and some systems are mobile enough to be ferried among regular conference rooms. These less-costly systems work over existing networks, yet the picture and audio quality surpass that of early-generation videoconferencing solutions. None come with amenities such as plush suites, but they closely match expensive systems' picture quality and usability.

Finally, there are classroom-style rooms that can hold 30 participants or more. These facilities, which are used by corporate and educational institutions alike, usually have multiple monitors or video projectors.

The cost of collaboration
Even with falling hardware costs, a telepresence system doesn't come cheap. A group system at a single site that can accommodate 18 to 36 users can go for $350,000. One reason for the expense is that you typically don't install telepresence systems in any old room. An immersive face-to-face environment requires special lighting, acoustics, and furniture, which all factor into the price. And that doesn't count in-house (or contracted) network and support costs.

The excellent LifeSize Express 200 costs $5,999 and delivers true high-definition video. See the review.

Hi Mike, Interesting article, but you forgot to include TANDBERG in your list of telepresence providers. The TANDBERG Telepresence T3 is the most sophisticated telepresence product available. It interoperates with all standards-based video conferencing and telepresence systems and even maintains the immersive telepresence experience when dialing into a third-party telepresence system. Check out this video that shows a TANDBERG T3 communicating with a Polycom RPX Telepresence system, Microsoft OCS, an iPhone, and several types of desktop and mobile video conferencing solutions at the same time http://www.tandberg.com/media/index.jsp?id=1482. There is no other product in the market that even comes close to the advanced capabilities of the T3. THIS is the type of interoperability that REALLY shatters communication barriers. Cheers!
