Japanese mobile phone jammers emit stronger radio waves than base stations, even if they are closer to the mobile phone than the base station. Therefore, according to the Radio Law, you need to apply to the Ministry of Internal Affairs and Communications before you can use it. It is now authorized as a mobile phone experiment station. The strange thing is that the one that has been put into actual use has been approved as an experimental station. However, according to the current Japanese law, the utility station of the mobile phone is assumed to be a base station owned only by the mobile phone operator. Therefore, it seems that a high license fee is required to become a practical station. In addition, for Cell Phone Jammer Legal Issues , the license fee is borne by the theater where the equipment is installed. It is impossible for theaters to pay the same license fees as mobile phone operators. On the other hand, if it is a test station, the license fee is 500 yen per vehicle per year. "Therefore, we consulted the Ministry of General Affairs and Transportation and treated it as an experimental station for the time being. At present, we are requesting the Ministry of General Affairs and Transportation to develop a frame mobile phone that is different from the experimental station and base station."

That's it. However, there is another problem here. If the radio wave is so strong, will it interfere with the wireless microphone? The frequency used by general wireless microphones (Type B) is 806M to 810MHz. Mobile phones use 810MHz and above, so it is easy to cause interference. According to Managing Director Kawamoto, Cell Phone Jammer Legal Issues uses proprietary technology to improve the accuracy of radio wave output and reduce the leakage of radio waves to surrounding frequencies to prevent interference. "I did a lot of tests, but they didn't interfere," said Kitazaki of the NHK lobby. In the NHK lobby, it seems that repeated tests have been carried out until a mobile phone jammer is actually introduced. In the NHK Concert Hall, not only concerts are held regularly, but also NHK public programs are recorded. There are many live shows. In case the wireless microphone or broadcasting equipment interferes with the mobile phone jammer and causes malfunction during the recording process, a broadcasting accident will occur. Therefore, he said that during the rehearsal of radio programs and concerts, he thoroughly checked whether the mobile phone jammers produced noise. Therefore, we thought there was no problem and decided to introduce it.
