RCM certification is a certification system implemented by Australia and New Zealand to ensure that electrical products comply with local safety, electromagnetic compatibility, and other standards.
FCC ID certification is a mandatory requirement under US law. The Federal Communications Commission (FCC) in the United States strictly regulates issues such as electromagnetic compatibility and radio interference in electronic products. As an electronic communication device, routers are only allowed to be sold and used in the US market if they have obtained FCC ID certification, otherwise they will face legal penalties and market bans.
CE-RED certification is a mandatory requirement for market access in the European Union. According to relevant EU regulations, all wireless devices entering the market must be certified by RED (Wireless Device Directive) to ensure compliance with EU standards.
