Mobile phone interference prevents nearby mobile phones from communicating

District of Columbia (WIS), South Carolina-The Department of Justice (DOJ) released a report on Wednesday showing that cell phone jammer device technology can function effectively in prisons without interfering with outside cell phones. Mobile phone interference prevents mobile phones in the prison from communicating with nearby mobile phones, making them unusable. The technology was tested for the first time at Broad River Correctional in Colombia in April. This is the first time it has been tested in a state prison. The report said that this technology has stopped cell phone signals in prisoners’ dormitories and can make calls with one foot outside the device. However, according to the FCC, interference with any type of cell phone signal currently violates federal law. According to the South Carolina Department of Corrections (SCDC), mobile phones are the most dangerous weapon in prisons today, posing a threat to other prisoners, the public and law enforcement personnel.

If you are one of the millions of consumers who have vehicle tracking devices on cars, trucks or motorcycles, then you may feel safe from thieves. If you are ready, you can even get a discount on car insurance. If your vehicle is stolen, the signal from the tracker will directly take the police there. Or will it? Most people don’t realize that it is easy for thieves to block tracking devices or cover up signals so that the police cannot find them. As thieves become more sophisticated, the efficiency of traditional vehicle trackers is getting lower and lower. The new tracking technology based on Sigfox’s powerful IoT network can provide vehicle owners with the required vehicle tracking protection.

In France, mobile phone interference in prisons has been a recurring theme. Since 2002, this law allows portable jammers to be installed in prisons. As of January 1, 2018, 110 prisons are equipped with 894 jamming devices, which is H. 60% of prisons. Question: Considering the development of mobile phones, previous devices have shown their technological limits. According to the Ministry of Justice, this new portable jammer system is not only suitable for 4G, but also for future 5G. It should also be adapted to the specific requirements of prison buildings-reinforced concrete walls, grids, bars-which limit the effectiveness of the old equipment. Mary Kretnott, advocacy director of the International Prison Observatory, said: “In the past, equipment used to ultimately encrypt only 2G (second generation technology) cost similar funds, so there will always be delays.
