Switzerland’s Federal Council has decided to postpone the assignment of mmWave spectrum for mobile communications until there is demand from the economy and the necessary environmental legal framework has been established.
The latter condition refers to the rules regulating the emission of non-ionising radiation, which has hindered the full utilisation of 5G technology by Swiss cellcos. Current legislation sets strict limits on radiation emissions, preventing operators from installing dense groups of mobile sites. The government has been reluctant to amend these rules due to public concern over the alleged impacts of radio signals on health and the environment. To address these concerns, in 2019 the Federal Office for the Environment (FOEN, or Bundesamt fur Umwelt, BAFU) began work on a long-term study to monitor exposure to electromagnetic radiation and its impact on health.
