Shhh! Even more quiet
When the TV-B-Gone is not enough to satisfy your needs, it is time to get out the heavy arms:
- The cellular jammer by AllProducts.com covers a 30 meter radius
- GlobalGadgetUK has a wide range of mobile jammers. Including jammers disguised as mobile phones
- This WiFi jammer should be a great anti PHB tool. Arrive early, grab the only RJ-45 and all other participants will be stuck without a network connection. Remember to bring the AC adaptor if you suspect a long meeting as the battery only lasts 1.5 hours.
