Nomadic computing allows mobile users to access and interact with information from any location using portable devices over wireless networks. It enables users to create, access, and communicate information without being tied to a single location. Current limitations include disconnection, low bandwidth, security and privacy risks, and the wide variety of devices with different capabilities. However, future growth areas for nomadic computing include improving device functionality, increasing bandwidth, and enhancing security. An example project was proposed to create a notification agent that could run on multiple devices and partner with organizations to establish a large install base and address basic notification needs.

3. The definition of the term “nomadic computing” has changed over time: According to the WiMAX forum, nomadic = semimobile. Semimobile means “At a minimum, the client mobile device is transportable to secondary fixed locations with no connection while in transit.” In broader industry, nomadic = mobile Mobile computing takes place when portable computing devices interact in some fashion with a central information system. Users access the Internet and data on their home or work computers while away from the normal, fixed workplace What is Nomadic computing?

4. More about mobile computing: Enables the mobile worker to: create, access, process, store, communicate information without being constrained to a single location Enables interaction with organizational personnel that were previously disconnected Ideally, users are not constrained to a single device Mobile computing aims to be “Ubiquitous and Pervasive” What is Nomadic computing?

5. Mobile computing is accomplished using a combination of: computer hardware, system and applications software, some form of communications medium Hardware : Palmtop, Clamshell , Handheld Penkey , Penslate , Laptop Software : MSDOS , Windows 3.1/3.11/95/98/NT , Windows for Pen Computing , Windows CE , PenDOS , PenRight , Palm OS , Psion EPOC32 , Unix Communication technologies : Wireless Local Area Networks (WLANs) , Satellite , Cellular Digital Packet Data (CDPD) , Personal Communications Systems (PCS) , Global System for Mobile communications (GSM) , RAM and ARDIS data networks , Specialized Mobile Radio (SMR) service , one and two-way paging , plain old telephone system (POTS) , Internet , infra-red,docking (serial, parallel, LAN),disk swapping Nomadic computing technology

21. A suggested exploratory/experimental project “Good Citizen Software” Addresses a basic human function ... to warn

22. GCS Phase I Objective: Build a simple notification agent that can run on multiple nomadic platforms. Build public good will. Partner with government and/or news organizations. Maximize the install base. Use only as needed. Establish test schedule. Profit Model: None / Charitable service

23. GCS Phase II Description: Leverage GPS technology to allow users to tag physical space Objective: Build a popular nomadic social network. Do not over-notify users. This service works because: It is mobile It is free It is platform independent Profit Model: None / Entertainment service

24. GCS Phase III Description: Market the data with business value. Objective: Establish a revenue stream. Profit Model: Market Intelligence

25. GCS Phase IV Description: Leverage a ubiquitous and pervasive install base. Objective: To be determined Profit Model: To be determined
