Mobile Cell Phone Signal Detector Device Causes Poor Network

Examination room Mobile Cell Phone Signal Detector Device is the most common wireless interference equipment in the examination room. Mainly to interfere with the mobile phone signal in the surrounding area, so that the mobile phone signal loses connection with the base station. The interference principle is: in a certain working frequency area, the mobile phone and the base station are connected according to electromagnetic waves, and the transmission of data information and sound is realized by a certain serial port baud rate and deployment method. For the above communication principle, the shield is in the operation link. The mid- and low-end curvature of the frequency band goes to the high-end scanner at a certain rate. The scanning rate can cause error code interference when the mobile phone receives the message format data signal, and the mobile phone cannot detect the regular data information transmitted from the base station, so that the mobile phone cannot establish a connection with the base station. Mobile phones are mainly manifested as searching the network, poor signal, no service system, etc.

Prison cell phone blockers have become a necessary addition to the arsenal of tools needed to protect prisoners. Cell phones are getting smaller every day, making it easier for prisoners to smuggle into facilities. It's a more difficult job for already overburdened correctional workers, but Mobile Cell Phone Signal Detector Device is a weapon that limits inmates' use of cell phones for potentially dangerous activities. Using a cell phone blocker can also force prisoners to use prison-approved/monitored phones. A school in Suzhou installed cell phone jammer in every classroom. Netizens believe that since the school is not a college entrance examination center, it is not very reasonable to install a mobile phone signal blocking device. It is usually open and hurts the interest of students and teachers. They hope to disable and delete the mobile phone signal blocking device. Of course, there are also those who think schools are doing the right thing. "Since I entered high school, every time I take an exam, the teacher will bring it into the classroom, and the power plug can be used, which is very convenient." Mr. Zhao said he did not know whether the device would be open normally because he did not have a mobile phone.
