Examining the Wireless Classroom

By Dr. Geoffrey H. Fletcher, Editor-In-Chief, T.H.E. Journal

A Borders bookstore in Orlando, Fla., The Green Mesquite BBQ in Austin, Texas, and Café Luna on Vashon Island, Wash. - what do they all have in common? People sitting in front of notebook computers or tapping on PDAs connected to the Internet courtesy of wireless technology. This new, increasingly common opportunity to connect to the Internet via a variety of technologies has made its way into the schools as well. I ran into a technology coordinator friend of mine at the Texas Computer Education Association (TCEA) Conference in Austin; she was chuckling about what wireless really meant for schools. Sure, it saves money, provides flexibility and allows a relatively easy expansion of networks. But, it also means kids are hanging out in cars in the school's parking lot late at night surfing the Net.

One issue of T.H.E. Journal cannot begin to explore all the aspects of wireless use in education, but this one is full of practical applications. This month's feature article, "Finding Waves: Techniques for a Successful Wireless Site Survey," provides a primer for the three most common methods of designing a campuswide WLAN. We also have an update from CoSN on wireless technology, as well as information on using wireless telephones to assist in school safety and communications. In addition, our applications stories chronicle different experiences with wireless technology:

  • St. John's University has installed a wireless network across its campuses throughout the New York metropolitan area.
  • The Charlotte-Mecklenburg Schools in North Carolina had a different task. They wanted to provide connectivity to all 540 mobile classrooms in their 148 K-12 schools.
  • The University of Memphis installed more than 1,100 wireless access points around its campus. They also use the system to link video cameras for surveillance of the university's public areas.

Wireless Trends

A few things became evident as we were putting this issue together. First is the dual ubiquity (if there is such a term) of this technology throughout our society. It truly is everywhere from coffee shops to airports to hotels. It also is in a growing number of technologies from laptops to PDAs to cell phones. And nowadays, it is not uncommon for people to disconnect their landline phone in favor of their cell phone.

Second, the application of wireless technology is similar across K-12 and higher education. You can read our feature story and applications articles and apply that information to all levels of education. While higher education tends to focus on deployment of a very widespread network serving thousands of clients, K-12 entities tend to focus more on COWs (computers on wheels) as an application of wireless technology. However, the commonalities of a secure, ubiquitous network are the same, no matter what the specific application. This is part of a larger trend of greater connections between K-12 and higher education (more on this trend in a future issue).

Third, wireless technology is getting significant traction in education at a faster rate than most of the technology coordinators and university CIOs I talk to anticipated.
