Mobile phone services, phone calls (voice), text messages (SMS) and internet (data), are transmitted through networks of mobile telephone masts.
These mobile networks have evolved over decades and will continue to do so. The first digital mobile network in Ireland was “2G”, launched in 1993. In the early 2000s, mobile networks evolved to “3G”. “4G” came in the early 2010s and, most recently, evolved again to “5G” in the early 2020s. Each evolution has been capable of faster mobile internet (data) services, which is the mobile service Irish consumers use most.
We have a web page with further information on 5G and the evolution of mobile technology. We also have a web page with further information on non-ionising radiation, the radio waves emitted from mobile networks.
