How do the certification requirements for signal boosters differ between the EU and non-EU countries

In the European Union, signal boosters must have CE marking, indicating compliance with EU safety and environmental requirements[1][5]. These devices must comply with regulations set by the European Telecommunications Standards Institute (ETSI) and the European Union to ensure they meet safety and performance standards[1]. They must not exceed the power limits specified in EU regulations to prevent interference, and proper installation according to the manufacturer’s instructions is mandatory[1].

Outside of the EU, specific countries have their own regulatory authorities and certification requirements for signal boosters[1]. For example, in the United Kingdom, signal boosters must be Ofcom-approved[1]. In Canada, Innovation, Science and Economic Development Canada (ISED) must approve signal boosters, and the device should have the ISED certification label[1]. Some regions may also require approval from mobile carriers before using a signal booster to prevent interference with the carrier’s network[5].
