Transportable System Design Goals Provide high-speed Internet access for ALL purposes, including computers, telephones and PDAs. Inexpensive to build and operate Off-the-shelf parts for easy duplication

Transportable System Design Goals (cont.) Easy to operate by one person with one day training, with NO hand tools. Small and light Reliable and adaptable to diverse field conditions Easily modified

Planned Applications Emergency communications. Provide distance learning in under connected locations such as rural areas and inner cities. Link field research to campus computers and laboratories and collaborators worldwide. Link field instruction and demonstrations to campus classrooms.

Planned Applications (cont.) Link field activities to remote databases, eg via PDAs. Special events, conferences, fairs, etc. Remote monitoring of construction projects.

Some Actual Applications National Farm Progress Show - rural Iowa Sept 2002 Distance Learning Conference, Worthington, Ohio October 2002 Kentuckyana Cattle Auction - rural Kentucky February 2003 Lewis and Clark Re-enactment, Pennsylvania to Oregon and back Ladysmith, WI School District Stark Co., OH Parks District Stark Co., OH Education District

Ladysmith-Hawkins School District Ladysmith, Wisconsin Students aiding the Wisconsin Department of Natural Resources tracking wolf pack locations. Involve classroom-based students in analysis of stream quality and release of brown trout. Virtual field trips to copper mines in Upper Michigan.

Stark/Portage (County) Area Computer Consortium school districts Ohio & Erie Canal National Heritage Corridor “Virtual tours” to promote site visits and hands- on research projects along the corridor and its associated rivers. Corridor as an outdoor classroom to monitor the impact of human and ecological activities and teach land stewardship.
