Plano, Texas schools see benefits from district-wide Wi-Fi

Computerworld - Wi-Fi has been around long enough to become a fact of life for many wireless users, and that's increasingly true in education settings in the U.S.

At the Plano Independent School District in Plano, Texas, 82 schools and office campuses are equipped with Wi-Fi offering separate private channels for teachers and staff and a public channel for students who bring in their own Wi-Fi devices to school.

The $4 million Wi-Fi project, finished in 2010, has helped guide instructional styles and even complements special collaboration spaces near classrooms at the district's newest building, McMillen High School, which opened this fall, school officials said. http://www.pisd.edu/news/archive/2011-12/mcmillen.high.school.shtml

Three of the newest schools are completely wireless and have no traditional Ethernet cabling to desktops, said Mitch Mitchell, assistant director of technology operations for the district, which serves 55,000 students and has 7,000 staff members. The 82 sites are served by 9,600 access points (APs) from Xirrus, which was able to provision the entire district with fewer APs than Wi-Fi competitors had offered, Mitchell said.

Not only does having Wi-Fi throughout the district allow students to bring personal devices to school, it also makes it easier to get information to teachers and students -- anywhere they want, said Mary Hewett, executive director of instruction technology.

"It does modify the way you teach," she said. "Wi-Fi is almost something teachers use without thinking because the computer isn't attached to the wall."

She said the McMillen school includes collaboration spaces where students can gather in small groups just outside of a formal classroom for work on Internet-based research.

"With collaboration spaces, the whole teaching model changed," she said. "That open space is an extension of the classroom where the small group of students can go to collaborate while others continue in the classroom."

She said the ubiquity of Wi-Fi is bound to impact future classroom designs.

For students who are normally accustomed to Wi-Fi at home, it's natural to expect it at school, Hewett added. "Wi-Fi is what they do in life, so now they bring it to school," she said.

Mitchell said there's plenty of capacity in the Wi-Fi system for growth, including bandwidth for streaming video and videoconferencing. The system already has an installed base of iPads and "every day, somebody wants to do something else with wireless," he said.

Testing of voice over Wi-Fi for telephones is also under way.

The Plano district said it got good support and a good price from Xirrus, a five-year-old vendor focused solely on Wi-Fi provisioning. The company has about $70 million in annual revenues and is staffed by 150 workers, said Xirrus CEO Dirk Gates. He said Xirrus is one of the top 10 Wi-Fi suppliers worldwide in what is a $3 billion annual Wi-Fi market led by Cisco and Motorola.
