In districts big and small across the U.S., students, teachers, and administrators alike have come to appreciate the benefits of wireless technology. Because the technology delivers Internet signals on airborne radio frequencies, wireless networking allows users of all portable devices to move freely on a school's campus and stay connected to the Internet. For those districts that need to add portable classrooms, the technology makes the job easier because it requires no additional wires, and wireless networks are easy to scale. Finally, technologists who have made the switch to wireless say that eliminating the costs associated with wiring a traditional network can save a district thousands of dollars, freeing up that money for software or other technology purchases. Still, the wireless revolution arrives with a host of challenges for K-12 districts. District administrators and technology coordinators agree that the first obstacle to wireless implementations is persuading teachers to get on board with them. According to Alice Owen, executive director of Technology for the Irving Independent School District (Texas), it is critical for districts switching to wireless to support their educators in learning the technology, and to know that having well-trained teachers always translates into better-educated students down the road.
