Wi-Fi, UbiComp, and SmartMobs

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 spacesSystem 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)

  • 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)
