  2. Always Best Communication - ABC • Users want to communicate with each other • Any place • Any time • Any device • How can we utilize wireless networks in supporting ABC?

  3. Simple Scenario • Session AND device mobility • A user is late for an online meeting • The system knows this from the user’s calendar • The system automatically dials the user’s mobile phone • Audio participation • The user reaches her office • This is noted by position awareness • The system automatically joins the online meeting and ask the user where she want the audio • In the mobile, PC audio or desktop phone? • User selects desktop phone on the PC screen and the call is transferred from the mobile.

  4. Problems • How to detect locality with good enough precision? • How to swap between different wireless and fixed carriers? • Carrier mobility • How to swap between devices • Session mobility • How to keep the current session running?

  5. Ubiquitous Human Communication

  6. Ubiquitous Human Communication • Imagine rich media sensors • Includes audio in (microphone) and audio out (speaker) • but not necessarily in the same device • Includes video in (camera) and video out (display) • but not necessarily in the same device • Not all in same device (might be 4 different) • Cheap • Doesn’t have to run on batteries • WLAN

  7. Available everywhere • We put these all over a work place • Offices • Corridors • Homes • Use together with good enough positioning of all users • Allow for “free” communication anywhere Ubiquitous Human Communication

  8. Problems • How to make the sensors cheap • Distributed echo canceling/suppression and multi-channel audio playback • Multi-view video grabbing presented • Several video views to multiple video display devices on the other side. • WLAN model when using high quality video feeds (sustained 1-25Mbps per video channel and several channels). • Power? • Perhaps skip WLAN and go for ethernet + power over ethernet instead?
