Cisco Systems has invested heavily in replacing global executive travel with telepresence, a video technology that is different from traditional and HD videoconferencing in that it gives users the feeling that they are actually in the room with offsite meeting attendees. Typically, a telepresence system consists of several 50-inch plasma screens to allow for life-size image display, cameras positioned to approximate eye contact, and surround-sound audio devices. The equipment is then placed out of view, which makes the room appear to be a regular conference room. A typical installation costs some $250,000, not including the exorbitant network charges for the services extraordinary bandwidth demands. Frost & Sullivan projected the global telepresence market would reach $145 million, up from $55 million in 2006, and that the market for telepresence would top $1.3 billion by 2013. Ciscos commitment to telepresence is helping to revamp videoconferencings reputation as a clunky, unreliable, unappealing alternative to expensive business travel. The company has been partnering in telepresence trials with BT and AT&T; the three have enabled large enterprise clients such as Wal-Mart and Procter & Gamble to try out the service between internal locations. According to Ciscos Marthin De Beer, the company will launch enterprise intercompany telepresence service in June 2008, which will be available for purchase through BT and AT&T.
