I have no function in the matter raised by the Deputy. This is a spectrum management issue for the independent Commission for Communications Regulation, ComReg. I am aware that the ubiquitous nature, and the often inappropriate use of mobile phones, has resulted in calls for restricted use in particular areas such as cinemas, theatres, hospitals. This has resulted in some cases of jammers which are prohibited under EU and Irish legislation, being installed illegally. By emitting electro-magnetic radiation, these devices interfere with the signal from the mobile phone and thus block all communications, including emergency calls.
Interceptors, on the other hand, do not prohibit the operation of mobile devices by means of emission of electro-magnetic radiation, but permit restricted use of mobile phones for emergency services and are not illegal. ComReg is seeking views on proposals for the use of such interceptors in Ireland. A response to this consultation will be published shortly.
