This Technical Report applies to electrical equipment using signals in the frequency range 1,6 MHz to 30 MHz to transmit information on low voltage electrical systems, either on the public supply system or within installations in consumers’ premises. It is a Technical Report covering the different standards for HF Power Line produced by SC205A. It points to related documents about: • Frequency bands, coexistence and filters. • Limits for the terminal output levels in the operating band. • Limits for conducted and radiated disturbance (product & installation EMC). • Measurement methods. It does not specify the signal modulation methods nor the coding methods nor functional features. Environmental requirements and tests are not included.
