Why use a anti-tracking GPS signal jammer?
We saw some details from movies:To avoid tracking of evil organization or reactionary gang, leading actors broke into pieces or threw into River.Here comes a question ,can obtain private information by mobile phone using in our real world ?In other words,are we facing the problem that tracked by smart phones using ?The answer is YES.Today ,we are going to share 3 ways to avoid the tracked problem.Before talking about these ways ,we’d like to remind you in previous that the best way is from cell phone signal jammer.
A mobile phone jammer or blocker is a device which deliberately transmits signals on the same radio frequencies as mobile phones, disrupting the communication between the phone and the cell-phone base station, effectively disabling mobile phones within the range of the jammer, preventing them from receiving signals and from transmitting them.If you need to block internet connections in the location around you then you must understand one thing: you cannot block cable internet unless you would cut that cable. But other types of internet like the wireless one powered by WiFi and Bluetooth connections can be easily jammed.
In prisons use this 4G jammer device
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 jamming 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.»
