Setting up a wireless network is easy enough. Place a few access points in strategic areas, then watch the network traffic fly! That approach may hold up reasonably well for a few dozen users, but there's no way it would support a schoolwide 1-to-1 program. Once students take to it with their wireless devices, "they're going to kill it," says Matt Federoff, CIO of Vail School District, southeast of Tucson, Arizona. At Birdville Independent School District near Forth Worth, Texas, Jonathan Abrams, the district's network engineer, says a temperamental network "used to keep people up at night, wondering if they were going to have an internet connection when they came in the next day." That's all ancient history now, six years later, since the district undertook an upgrade of its network and wireless infrastructure. As Federoff and Abrams can say with authority, the way to building a wireless network that's reliable, scalable, and secure enough to support a robust mobile-learning initiative demands taking care of four imperative steps: (1) Get Physical; (2) Separate and Unequal; (3) Mind Your APs; and (4) Speed It Up.
