At the request of the Brussels Region, the BIPT carried out a study in September 2018 already, to determine which radiation standards would be necessary to roll out mobile 5G networks. The technical report regarding the impact of the current Brussels radiation standards on the roll-out of mobile networks concluded that, taking into account the expected increase in data traffic and a desired roll-out of 5G, the radiation standards needed to be adjusted.
The radiation standards have meanwhile been revised in line with the development of 5G.
- In the Brussels-Capital Region, the Ordinance of 1 March 2007 on the protection of the environment against the possible harmful effects and interference of non-ionising radiation sets a cumulative limit of 0.5635 W/m² (or about 14.5 V/m).
- The Order of the Flemish Government of 1 June 1995 laying down general and sectoral provisions on the environmental hygiene (VLAREM II) sets a cumulative limit of 20.6 V/m at a frequency of 900 MHz.
- In the Walloon Region, the Decree of 3 April 2009 on the protection against the possible harmful effects and interference of the non-ionising radiation generated by stationary transmitters lays down a limit per operator of 9.2 V/m and a cumulative limit of 18.4 V/m for a frequency of 900 MHz at the places of residence.
