With the development of intelligent technology, the price of mobile phones is getting cheaper and cheaper, and the number of people who can use mobile phones in hospitals is increasing. However, it is undoubtedly necessary to ensure a secure environment for hospitals. Problems, the signal jammer approved by the Ministry of Communications for use as an experimental station will also be tested in actual hospitals.
The signal blocking device is a deterrent device that has the function of “stopping” the mobile phone to a specific space, protecting medical equipment from the failure caused by the electromagnetic wave emitted by the mobile phone, and can also shield the mobile phone from being mixed. Noise, reducing the impact of mobile phone noise on patients.
In Japan, in order to use radio waves safely and reliably, the Ministry of Internal Affairs and Communications has established radio wave intensity standards based on the results of domestic and foreign research over the past decades, and has formulated regulations in accordance with the Radio Law. Where the intensity of radio waves emitted by, for example, mobile phone base stations and broadcasting stations exceeds the standards of radio wave protection guidelines, fences and the like will be provided to prevent ordinary people from entering. It can be seen that the use of signal jammers will be more common, which has a significant effect on shielding radio waves.
