2. Overview Clarify terms Review related readings References

3. 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”Wi-FI Alliance –hired Interbrand to come up with the name and logoInterbrand More WiFi news: Wi-Fi Net NewsWi-Fi Net News

4. 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 

5. Define: UbiComp UbiComp = Ubiquitous Computing Mark Weiser coined the term in the late 80’sMark Weiser UbiComp forces the computer to live out here in the world with people Also known as Pervasive Computing

7. 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 RheingoldSmartMobs

8. System Directions for Pervasive Computing Pervasive computing focuses on deploying smart devices through our working & living spaces Grimm, R., Davis, J., Hendrickson, B., Lemar, E., et al. (2001) 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

9. System Directions for Pervasive Computing Argument: Existing approaches to distributed computing are flawed along three Fault Lines when applied to pervasive computing. 1. Application data and functionality need to be kept separate 2. 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 3. Pervasive computing requires a common system platform allowing applications to run across a range of devices Grimm, R., Davis, J., Hendrickson, B., Lemar, E., et al. (2001)

10. 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)

11. 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)

12. Wired Magazine Article: Unplugged U.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)
