Electrical devices are subject to standards that limit the emission of high-frequency interference. The standard EN 50561-1 (Power line communication apparatus used in low-voltage installations - Radio disturbance characteristics - Limits and methods of measurement - Part 1: Apparatus for in-home use) applies to FRITZ!Powerline adapters.

Radio reception is generally restricted to the FM band between 87.20 MHz and 108.00 MHz. The frequency range of FRITZ!Powerline adapters is well below the FM band. Within the frequency range of amateur radio, FRITZ!Powerline adapters transmit at a low level. The transmitter power of FRITZ!Powerline adapters is comparatively low anyway, and due to symmetrical coupling, an even smaller part of it is radiated through the power line.
