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 dÎμÎ/m at 10 meters for inductive devices[1]
* 9-315 kHz: 30 dÎμÎ/m at 10 meters for active medical implant devices, with a duty cycle limit of 10%[1]
* 59,750-60,250 kHz: 42 dÎμÎ/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 dÎμÎ/m at 10 meters for inductive devices[1]
* 148,5-5 000 kHz: â 15 dÎμÎ/m at 10 meters in any bandwidth of 10 kHz; total field strength is â 5 dÎμÎ/m at 10 m for systems operating at bandwidths larger than 10 kHz for inductive devices[1]
* 400-600 kHz: 13,5 dÎμÎ/m at 10 meters for Radio Frequency inductive devices[1]
* 5 000-30 000 kHz: â 20 dÎμÎ/m at 10 meters in any bandwidth of 10 kHz; total field strength is â 5 dÎμÎ/m at 10 m for systems operating at bandwidths larger than 10 kHz for inductive devices[1]
* 6 765-6 795 kHz: 42 dÎμÎ/m at 10 meters for inductive devices[1]
* 7 300-23 000 kHz: â 7 dÎμÎ/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]
