Wi-Fi, UbiComp, and SmartMobs

Valerie Gomez de la Torre | KMS i385Q | Dr. Turnbull |11.17.05


Overview

Overview

  • Clarify terms

  • Review related readings

  • References


Define wi fi

Define: Wi-Fi

  • Wi-Fi does not stand for “Wireless Fidelity”

  • It is not an acronym. There is no meaning.

  • As a trademark, it isn’t allowed to have a pre-existing meaning in the realm in which it is registered

  • The Wi-FI Alliance wanted something catcher than “IEEE 802.11b Direct Sequence”

    • hired Interbrand to come up with the name and logo

  • More WiFi news: Wi-Fi Net News


Why wi fi warchalking died

Why Wi-Fi Warchalking died

"Warchalking is the practice of marking a series of symbols on sidewalks and walls to indicate nearby wireless access. That way, other computer users can pop open their laptops and connect to the Internet wirelessly."

Challenges:

  • Grassroots effort

  • Amateurs

  • Defacing buildings is illegal

  • Requires maintenance

  • Wi-Fi Logo 


Define ubicomp

Define: UbiComp

  • UbiComp = Ubiquitous Computing

  • Mark Weiser coined the term in the late 80’s

  • UbiComp forces the computer to live out here in the world with people

  • Also known as Pervasive Computing


Define smartmobs

Define: SmartMobs

  • Consist of people who are able to act in concert even if they don’t know each other. They emerge when communication and computing technologies amplify human talents for cooperation

  • Impacts from SmartMobs have been +/-

    • Location-based matchmaking

    • Organized gang killing using text messages

  • SmartMob Technologies

    • Mobile communication devices

    • Pervasive Computing

  • More information: SmartMobs, Howard Rheingold


System directions for pervasive computing

Pervasive computing focuses on deploying smart devices through our working & living spaces

System Directions for Pervasive Computing

The infrastructure necessary to

seamlessly and ubiquitously

provide applications is almost a reality

There are difficulties when

designing, building, and deploying

applications in a pervasive computing

environment

  • Grimm, R., Davis, J., Hendrickson, B., Lemar, E., et al. (2001)


System directions for pervasive computing1

System Directions for Pervasive Computing

  • Argument: Existing approaches to distributed computing are flawed along three Fault Lines when applied to pervasive computing.

  • Application data and functionality need to be kept separate

  • Applications need to be able to acquire any resource they need at any time so that they can continuously provide their service in a highly dynamic environment

  • Pervasive computing requires a common system platform allowing applications to runacross a range of devices

  • Grimm, R., Davis, J., Hendrickson, B., Lemar, E., et al. (2001)


T spaces the next wave

T Spaces: The Next Wave

  • A network middleware package for the new age of ubiquitous computing

  • Enables communication between applications and devices in a pervasive computing environment

  • To connect all devices we must have a common language platform on which to run

  • Lehman, T., McLaughry, S.W., Wycko, P. (1999)


Fieldwise a mobile knowledge management architecture

FieldWise: A Mobile Knowledge Management Architecture

  • KM, Mobility and CSCW

  • Findings from empirical studies & fieldwork:

    • People’s tasks are time critical and driven by deadlines

    • Results rely on the creativity of autonomous, but interrelated people

    • There is a culture of co-operation and sharing of knowledge amongst people

    • People are mobile and distributed

  • Fagrell, H., Forsberg, K., Sanneblad, J.. (2000)


Wired magazine article unplugged u

Wired Magazine Article: Unplugged U.

  • Dartmouth College’s campus-wide wireless network

  • The Wi-Fi network is changing:

    • Teaching techniques

    • Social interaction

    • Study habits

    • Security

      Innovations in consumer technology must become

      part of the background of everyday life…

       the tool itself is an afterthought

  • McHugh, Josh (2002)
