The Campus Computing Project says 51.2 percent of college classrooms have wireless network access: That compares to 42.7 in 2005 and 31.1 percent in 2004, they state in a new survey. 68.8 percent of surveyed campuses have a strategic plan for deploying wireless, too. The survey found that community colleges have substantially fewer wireless classrooms than four-year colleges and universities. Network and data security was selected by 30 percent of respondents as their single most important IT issue, which goes hand in hand with wireless networks.
