Convergence of telecommunications, datacommunication and distributed computing technologies
expand beyond traditional
services
with new information
services
and paradigms that combine:
mobility, multimedia, user adaptivity, guarantees of security and reliability, extreme performance requirements, and customizable "virtual" network mechanisms.
The applications conceived here raise demands on terminal artefacts and infrastructure, such as:
- integrated personal computing and communication devices (PCC artefacts) of different complexity, wirelessly connected to a high performance infrastructure with servers
- high availability with respect to the ease of use, portability and appeal of PCC artefacts.
- ubiquitous access, i.e., high availability with respect to connectivity even for work in very diverse and dynamic environments
- multicast network supporting group communication services
- quality of service requirements
- QoS-guarantees for ineractivity and audio and video streams
- bandwidth > 10 Mbit/s both uplink and downlink in the wireless access
- roundtrip delay: in highly interactive applications < 10-30 ms
- delay variance both in (audio/video) streams and between streams
Generic Application: Support for Meeting Processes
(a subproblem of CSCW)
Objectives:
- online support for individual meetings which may be either face to face meetings, conferences on voice telephone, video conferences, live board working group meetings, synchronous computer mediated communications (e.g., a MOO world), asynchronous computer mediated meetings (e.g., a BBS).
- support for booking of individual meetings assuming that the potential participants, or resources, all have electronic calenders as well as support the preparation of each meeting, sharing relevant information through fax, voice phone, picture phone, shared online documents (www or other), email, paper mail, etc. The participants could be individuals or resources involved in some sort of event, a media-on-demand session.
- support the whole meeting process, providing an overview of all participants in the meeting process, past, present and future meetings, logs of materials sent around by different media etc.
[Lets face it: the major activity in Swedish business is meetings, so if we can't eliminate them, at least we should make them more useful.]
Hence the first concrete subproject: MEET-PCC
Specific graduate study topics for a first generation of graduate students
Recruitment of project leader: potentially Thad Starner
Lots of meeting, more meeting, and more meetings ...
Lots of effort for student recuitment

Personal Computing and Communication (PCC)
Upper limit of bandwidth: saturate the senses: sight, sound, touch, smell, taste
~1 Gbit/sec/user
Current workstations shipping with 1 Gbit/sec interfaces for LAN!
Telepresense for work is the long-term "killer" application

Intel's Road Map for Notebook Features 2
Mainstream notebooks: Pentium II processors, DVD-ROM, MPEG2 video and AC3 Audio
- MPEG2 through software decoding -- not hardware
- 3-D graphics
- video conferences via digital video camera into a universal serial bus ( USB ) port
- doubling of the DVD-ROM drive's speed
- hot swappable devices
- "power friendly" applications can be written to increase battery life
"... It will be possible to put a 100+ MIPS CPU and a 0.5 GFLOP DSP in a $200 Nintendo Game Boy within 2 years, for less than $25 bucks of Si cost. With this kind of cheap, available cycle time, how hard would it be to add a communications cartridge/dongle into a game slot? ..."

50 years: Auxiliary brain
- a single chip storing 2x10 16 bits of data, ~storage capacity of 10 5 human brains.
- volume of 1 cubic centimeter, about the size of a sugar cube.
- with power of 500 million Pentium Pros
- able to record life's experiences and replay them
