## Key values

- **Limit value:** 18.4 V/m — Regulatory value — legally enforceable — Art. 4 §2 bounds the combined field of every operator's antennas at a shared site — twice the per-operator figure in field strength, four times in power density. Mobile-network antennas radiating between 20 and 300 GHz are not authorised in Wallonia, excluding point-to-point links. [wallonia-decree-2009, wallonia-decree-2022-report]
- **Quantity:** electric field strength
- **Frequency band:** 900 MHz reference
- **Population:** general public
- **Set by:** Wallonia stationary transmitting antenna decree (Decree of 3 April 2009, as amended by the decree of 8 December 2022)
- **Kind:** Regulatory — legally enforceable

## Related records

- [Wallonia stationary transmitting antenna decree](https://emfbase.com/standards/wallonia-stationary-antenna-decree): Wallonia replaced its 3 V/m per-antenna limit with 9.2 V/m per operator plus an 18.4 V/m cumulative limit in places of stay, and bans public mobile antennas from 20 to 300 GHz.
- [Wallonia per-operator limit in places of stay](https://emfbase.com/limits/wallonia-per-operator-limit): 9.2 V/m at 900 MHz for all of one operator's antennas on a single support — the value that replaced the much-quoted 3 V/m per antenna in December 2022.
