Recently, I had to overview some WiFi technologies, and then wanted to check RADIOSIGNAL-BLOCKER hardware (a.k.a. WiFi/Cellural-Signal/Bluetooth/ Jammer).
We needed to use that technology to block mobile-phones in our hall, to avoid noise during some important events.. But I was interested, if it is harmful for peoples health (for example, averagely 3 hours a day it will be turned ON in our office).
thanks in advance
