Universities looking to pass technology test

More than a million students arrived on Chicago-area campuses, giving university technology departments good reason to be on edge. Students are bringing with them more wireless Internet-dependent devices, many with bandwidth-gobbling applications including video streaming and online gaming. The average number of devices per student has doubled in recent years to four, which means university technology managers have to be several steps ahead of wireless demands. Particularly challenging are spots where students tend to gather — libraries, student centers and residence halls. Older buildings don't help, either, as they are less likely to have upgraded technology.
