5G in Switzerland: what is behind it?

Few technology topics are discussed as emotionally in Switzerland as 5G. Some look forward to faster internet, others are worried. Here are the key facts, factual and with sources.

What is 5G?

5G is the fifth generation of mobile communications. It transfers more data faster and can connect more devices at the same time. What is new are so-called adaptive antennas, which direct their signal more precisely towards users.

In Switzerland, 5G currently runs on frequencies that have long been used for mobile networks and Wi-Fi. The Ordinance on Protection against Non-Ionising Radiation (ONIR) does not distinguish between 2G, 3G, 4G or 5G, but limits radiation as a whole.

Which limits apply in Switzerland?

Switzerland has two kinds of limits. The ambient limits largely correspond to international recommendations. In addition, precautionary installation limits apply at places of sensitive use such as homes, schools, hospitals and workplaces. For mobile networks they are about ten times lower.

What does research say?

Research on weak high-frequency radiation is not complete. Many studies find no health effects when limits are respected, some report indications of biological reactions. The Federal Office for the Environment has therefore been measuring public exposure regularly since 2021 and continuously reviews the state of research.

What you can do yourself

You cannot influence the antenna on the roof. But most of your personal exposure comes from the devices you carry close to your body. Here, it is up to you:

1. Good reception helps. With a good network your phone transmits at lower power. Make calls where reception is strong.
2. Use headphones or the speaker. That keeps the phone away from your head during calls.
3. Airplane mode at night. Your bedroom becomes an offline zone.
4. Conscious breaks. Fixed screen-free times are good for your nervous system, regardless of radiation.

And VIVOBASE?

VIVOBASE is not a shield and changes neither reception nor network. Many people use VIVOBASE as a simple basis for a calmer home and more balanced days. VIVOBASE has been examined in studies by the BION Institute. Individual experiences may vary.
