What are the specific power limits for signal boosters in the EU


In the European Union, signal boosters must adhere to regulations set by the European Telecommunications Standards Institute (ETSI) and the EU[3]. These regulations ensure that signal boosters meet safety and performance standards[3]. Devices must not exceed the power limits specified in EU regulations to prevent interference[3].

Specific power limits for short-range devices in the EU, according to frequency band, include:
* 9-59,750 kHz: 72 dΒμΑ/m at 10 meters for inductive devices[1]
* 9-315 kHz: 30 dΒμΑ/m at 10 meters for active medical implant devices, with a duty cycle limit of 10%[1]
* 59,750-60,250 kHz: 42 dΒμΑ/m at 10 meters for inductive devices[1]
* 60,250-74,750 kHz: 66 dBµA/m at 10 meters for inductive devices[1]
* 135-140 kHz: 42 dBµA/m at 10 meters for inductive devices[1]
* 140-148,5 kHz: 37,7 dΒμΑ/m at 10 meters for inductive devices[1]
* 148,5-5 000 kHz: – 15 dΒμΑ/m at 10 meters in any bandwidth of 10 kHz; total field strength is – 5 dΒμΑ/m at 10 m for systems operating at bandwidths larger than 10 kHz for inductive devices[1]
* 400-600 kHz: 13,5 dΒμΑ/m at 10 meters for Radio Frequency inductive devices[1]
* 5 000-30 000 kHz: – 20 dΒμΑ/m at 10 meters in any bandwidth of 10 kHz; total field strength is – 5 dΒμΑ/m at 10 m for systems operating at bandwidths larger than 10 kHz for inductive devices[1]
* 6 765-6 795 kHz: 42 dΒμΑ/m at 10 meters for inductive devices[1]
* 7 300-23 000 kHz: – 7 dΒμΑ/m at 10 m for Transport and Traffic Telematics devices[1]
* 446,0-446,2 MHz: 500 mW e.r.p. for PMR446[1]
* 862-863 MHz: 25 mW e.r.p. for Non-specific short-range devices, with a duty cycle limit of 0,1 % and Bandwidth ≤ 350 kHz[1]
* 863-865 MHz: 25 mW e.r.p. for Non-specific short-range devices[1]
