Such jammers transmit radio signals in the 800MHz frequency band, which is used as the mainstream carrier frequency band for NTT DoCoMo and KDDI au phones. Products targeting other frequency bands are also available.

This is because as the number of mobile phone users grows, there is an increasing need to disable mobile phones in certain places where mobile phone ringing is annoying. These locations include places of worship, university lecture rooms, libraries, concert halls, conference rooms, and other places where silence is allowed.
