The threat of radio interference to national security

One of the major concerns about the request from the GOP governors is that the technology they are asking for could be used to block public airwaves. This means that state or local authorities would have access to the type of technology that could shut down cellphone calls even outside of the prison. According to a 1934 federal law, the FCC can only give permission to federal agencies to block public airwaves, and state agencies are not allowed to do so. This recent request would extend that authority to state agencies within the context of prison facilities.

Cell phone jammer is a device that is used to block signals by jamming Bluetooth or wireless signals for cell phones, GPS signals, and Wi-Fi systems. Jammers flood a specific area with noise that covers the radio bands to be jammed. Jammers can be used for many reasons, such as preventing unwanted calls from telemarketers; as well as keeping people in certain venues, such as restaurants, from using their cell phones in that specific vicinity. Law enforcement and intelligence professionals also have been known to use this technology when dealing with crises such as hostage situations and bomb threats. Despite it’s many uses, there are some states that prevent the use of jammers, and this should be checked prior to purchasing one.

Leave the vicinity in which the signal jammer is being used to prevent radio frequencies in that area. Jammers normally cover up to 30-80 feet of space used to jam radio frequencies in that area. Simply drive or walk away as far as possible from the jamming vicinity in order to regain the use of your electrical device.

A British top policeman has proposed a punishment for teenage hackers: force them to wear Wi-Fi jammers to block them from accessing the internet.

Chief Superintendent Gavin Thomas, president of the Police Superintendents’ Association (PSA), suggested that Wi-Fi jammers around the wrists or ankles could be a better sentence for young offenders.

The jammer is too small, you can put it in your pocket and carry it with you. It can be powered by your power supply or 3.7v LiPo battery. You can choose which WiFi network you want to block and attack it. But make sure that it is for educational purposes only; do not use this for the wrong purpose.

Talisay City Jail Warden Chief Inspector Josephus Jelianggao said he preferred that the jail should also have a signal jammer to prevent the illegal use of mobile phones inside the facility.

But Talisay City Mayor Eduardo Gullas said there is no need to install a signal jammer since anomalies can be prevented if jail rules are strictly implemented.
