Signal Jamming is the New Black: How LDMOS Technology Blocks Prisoners from Using Cell Phones

by Jaymie Murray 7. October 2015 09:25

Prisons and other correctional facilities are facing an increasingly daunting technological challenge. Contraband cell phones smuggled in by prisoners pose a tremendous security threat to the safety of both staff and inmates alike. While security screenings are designed to identify and dispose of such contraband before it enters a secure facility, at times these phones can slip through the cracks and end up in a cell along with an inmate. Correctional facilities are in need of a solution that prevents contraband cell phones from being used from within the prison walls. The Communications Band Signal Jamming Power Amplifier from API Technologies is that solution. The amplifier operates on the standard communication band frequencies, jamming cell phone signals and rendering the phones inoperable.

Cell phone smuggling has become an increasingly unmanageable problem for prisons and other correctional facilities. These phones pose a significant security threat and can be used to endanger the welfare of correctional workers as well as other inmates, or to coordinate escape attempts. While the first line of defense against this threat is to prevent the phones from entering correctional facilities in the first place, many often slip past security screenings and wind up in the hands of inmates. It has become increasingly apparent security screenings aren't sufficiently mitigating this threat, and there is a significant need for technology that prevents prisoners from making cell phone calls. There is a solution available to rectify this significant problem. API Technologies' signal jamming power amplifiers utilizing LDMOS technology are designed to operate in a band of 1930 to 1990 MHz to jam typical communication band frequencies. These power amps can offer a minimum output power of 100 watts with a gain of 50dB, with multiple carrier inputs. Typical current draw from a nominal +28 VDC supply at rated output power is 8 A. API's designs offer an isolator-protected output to guard against transistor failure due to infinite VSWR mismatch. This jamming renders cell phones inoperable and prevents calls or texts from being sent, rendering the phones essentially useless and mitigating any potential security threats posed by them. Other Applications for Signal Jamming Prisons aren't the only place where cell phone signal jamming is necessary. There are many instances where having access to a cell phone signal could pose a security risk, such as in government buildings, or violate policies, such as in a test taking facility.
