Sometimes the jamming signal arriving at the receiver input, can be lower than the communication (“partner’s”) signal and still prevail. This is happening because usually the receiver needs a certain “margin” between the two signals at its input, in order to be able to interpret one of them (usually the stronger one). However, in advanced […]

Margarita Escobedo, a Catholic who goes to church at least twice a week and volunteers at the San Genaro church, says she would welcome the signal jammer in her parish, where cell phones are becoming a nuisance. The Perfectjammer works by directing radio energy at the drone, disrupting the remote control link between the drone and the […]

The drone is a hexarotor and, as reported by China’s state-owned ECNS news service, it will scan for suspicious radio signals from exam-takers.
