resence room equipped with high-quality video, in a conference call and cannot accept any phone call, in car and can talk only via cell phone, or in a remote office near a desk phone. If multiple modes are available, the system knows which way of communi- cating the person prefers or is most appropriate at any particular time. The system can also be capable of working with other applications. For example, it can set up a collaboration session on a document you are developing with another person. It can also seamlessly access back-office data. The productivity increase comes from doing things more quickly, no matter where other people are located. Another thing that can make UC special is that it can work over any type of IP network-if there is enough bandwidth. End users will like UC because connectivity will be simplified. Specifically, it can offer users a single logon and authentication to access all the various modes of communica- tion. It also can change the whole paradigm of communicating with people, moving away from the idea that there are multiple ways of reaching you. To contact you, someone can select your name, and the communication is mapped to whatever is available to you. Chapter 13: Future of Unified Communications 301 Cisco CEO John Chambers says, "That's the future. It's a hard concept [to understand], but it goes right to the issue of increased productivity. I clearly communicate at 200 words a minute, and I'm much better with the video capability that goes with it." The way young people communicate now, through video, text messaging, and social network- ing sites, is how enterprises will communicate in the next few years, he added. Mobility Provides Access Anytime The networks that will handle the increased IP traffic due to UC are still. Fast wireless networks are only the beginning of the sea of changes in mobile communications. According to pundits, we'll soon live in a world in which the network will locate anyone for you, tell you how best to make contact, and, after making contact, suppo
