ABSTRACT:
A device for blocking cellular phone signals includes a housing having a substantially rectangular shape and further includes a transceiver disposed therein for detecting a cellular phone signal. The transceiver generates a blocking signal to temporarily disable a cellular phone and thereby prevent a user from operating a cellular phone within a predetermined area. The housing further has a top surface and a bottom surface including an antenna connected thereto and for directing the blocking signal outwardly and away therefrom. The device further includes a power supply source including a rechargeable battery pack for providing power to the device and a control lever connected to the housing and operably connected to the transceiver for selectively adjusting the strength of the blocking signal as desired by a user.
