When the phone’s battery starts up and the bell rings, a satisfying energy spark that causes a slight spark may cause a fire. For the safety part, it has been a long time since the regulation of petrol stations to stop the use of mobile phones was put in place, but now the performance is not satisfactory.Gas station equipment is controlled by computer, wifi jammer affects the normal operation of equipment, causes the banning of measurement, more important is that mobile phone in the process of call can present a spark, vulnerable to fire, gas station blasting. Installing mobile phone jammers at gas stations could prevent some tragedies.
In January, NTIA said its researchers installed the jamming technology in a utility closet adjacent to a 13-by-eight foot cell on the ground floor of the prison’s housing unit, according to the study. It successfully blocked cellphone transmissions in commercial bands between 700 and 2170 MHz, but did not disrupt commercial transmissions when monitored at 20 feet and 100 feet outside the cell, said the study.
To completely cover a prison facility, a fleet of the systems would be required — up to 100 gps jammer systems — which could lead to significant power issues, NTIA’s study said.”The results indicate the potential for localized impact of this micro-jamming technology,” Williams said. “That is an encouraging sign that brings us closer to a solution that will make our communities safer and help prevent the continuation of criminal activity from inside prison walls.”
The work is currently underway to develop an aircraft equipped with jamming systems that will replace Il-22PP Porubshchik [electronic warfare aircraft], which are currently being delivered to the Russian Aerospace Forces,” an unnamed Russian defense industry source told Sputnik News. “This machine will receive a fundamentally new on-board equipment, which will allow to conduct electronic suppression of any targets—ground, air, sea—and disable enemy satellites that provide navigation and radio communication on the ground.
GPS jammers can be bought on the internet and range in size from that of a small cigarette lighter to a suitcase, with a range of a couple of metres to a couple of hundred. You can buy combination jammers that also block mobile phones, all for a few hundred dollars. Customers for these devices are drivers seeking to shut off their employer’s GPS tracker from their vehicle, car thieves and other criminals.
