Device allegedly jams Google Glass wifi access

Except it is actually illegal to block cell phone frequencies, right? Since cell phone jamming is pretty much indiscriminate and blocks every cell phone using targeted frequencies within range? And since cell phones are part of the whole emergency response and 911 network... so, actually nothing at all like cell phone jammers.

This detects specifically MAC ranges used by Glass and targets only those, with a Wi-Fi disconnect exploit. Comparing it to a cell phone jammer is like comparing a scalpel to a machete.
