Cell Phone Jammers Violate Citizens’ Freedom of Communication

In order to prevent employees from playing with mobile phones during work, the company has ingeniously activated mobile cell phone signal jammer , which resulted in complaints from surrounding residents. A few days ago, the radio management department of Qingyuan City came to the door in time to eliminate the signal interference, and criticized and educated the enterprise.

“The mobile phone signal disappeared inexplicably, and it can be restored after walking outside a certain range. It’s too strange.” Recently, the Qingyuan City Radio Management Office received a complaint from a mobile phone user, reflecting that the communication base station near Jiafu Industrial Park was affected by unknown interference. As a result, the two sectors cannot work normally, affecting the normal communication of a large number of users. The office immediately dispatched radio law enforcement officers and monitoring personnel to the interference area to investigate. After testing, it was found that the interference signal came from the factory of a travel goods limited company in Jiafu Industrial Park.

The person in charge of the company explained that in order to keep employees from going to work without delaying their work, they purchased a GSM signal shielding device to prevent the phenomenon of playing with mobile phones during working hours. The impact is very sorry and promises to remove the cell phone jammer immediately. Treating him as a first-time offender and actively cooperating with government law enforcement, the Qingyuan Radio Management Office issued a warning to the enterprise.

According to the introduction of professionals, the mobile phone jammer scans from the low-end frequency of the forward channel to the high-end frequency at a certain speed. The scanning speed can cause garbled interference in the message signal received by the mobile phone, so the mobile phone cannot detect the normal data sent from the base station, and thus cannot establish a connection with the base station.

At present, the price of such mobile phone jammer equipment is around several thousand yuan, which can be purchased at will on the Internet. In fact, cell phone jammers have always been controversial. Many citizens believe that if the device is abused, it will affect citizens’ freedom of communication.

The Radio Regulatory Department pointed out that cell phone signal jammers must be reported to the Security Bureau and the Radio Regulatory Authority for approval before they can be used. Even if it is approved, it can only be used during the confidential meeting, under the responsibility of special personnel, with a fixed power and a fixed scope. Unauthorized use of such equipment by enterprises or individuals is a violation of the national radio management regulations and will be punished according to the circumstances and consequences.

If there is a company blocking the mobile phone signal, the department will intervene in the investigation and order it to stop using it, and ask the company to make rectification.

Organizations and individuals who install devices such as cell phone signal jammers without approval from relevant law enforcement authorities are suspected of violating citizens’ freedom of communication.
