The limit values for radiation for antennas have not been relaxed; the immission limit values and installation limit values remain the same. When deriving the limit values, the radiation of all antennas of an installation is added together. The precautionary principle laid down in the Environmental Protection Act remains in force. See the FOEN's explanations on this subject (only available in German, French and Italian).
The newly allocated frequencies are in the same range as those used for 4G. Their properties are very similar and have been known for many years, as these frequencies have been used for other applications, some of which are still in use. The use of millimetre waves for mobile communications is not allowed. The Federal Council would first have to approve this development (see Who is responsible for what in terms of 5G?)
The approval procedures for the construction or conversion of antennas and the objection procedures remain the same: cantons and municipalities must check whether the antennas comply with the radiation limit values and the building regulations.
Before applying for planning permission for a new mast outside the building zones, the operators must check whether they can install the antenna on an existing mast.
By the way, you can check the price of 5G Devices.
