This is a powerful pocket-sized cell phone signal shield that disables nearly all kinds of cell phone signals, including the new 3G band (and 4G/LTE 1800 [Band 3]). It can be discreetly placed out of sight, put in a handbag or pocket. The device produces a 1 W radio shield with an effective range of up to 10 meters.
Ideal for meeting rooms, restaurants, concert halls, offices, schools – any place where cell phone use is inappropriate. Keep students from text messaging during tests, and keep unwanted phone calls from disrupting religious services.
