Bob, I can't confirm that kids are using frequencies on their wireless devices that teachers can't hear, but my son is a highschool teacher somewhere in the USA. He purchased a device that plugs into any electrical outlet that blocks airwave transmissions for about a 30 foot radius. If he suspects his kids are getting involved with texting & such during class, he discretely plugs in the unit & enjoys seeing the confused looks on his students's faces.

According to the reports, they use custom ring tones that sound at frequencies higher than those perceivable by the teachers. This is because high frequency sensitivity falls off with age, so the young people can hear the high pitch squeeking of a cell phone but the teachers/professors cannot. I'm a little incredulous, because I wonder if these little devices can reproduce such high frequencies in their ring tones. Has anybody been able to confirm this?
