IEC 62488-1:2025 applies to the planning of analogue (APLC), digital (DPLC) and hybrid analogue-digital (ADPLC) power line carrier communication systems operating over HV electric power networks. The object of this document is to establish the planning of the services and performance parameters for the operational requirements to transmit and receive data efficiently and reliably.

Such analogue and digital power line carrier systems are used by the different electricity supply industries and integrated into their communication infrastructure using common communication technologies such as radio links, fibre optic and satellite networks

This second edition cancels and replaces the first edition published in 2012. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:

a) Complete revision of this edition with respect to the previous edition with the main focus on planning of analogue and digital power line carrier systems operating over HV power networks

b) A general structure of a bidirectional point-to-multipoint APLC, DPLC or ADPLC link has been introduced

c) Introduction of a new approach for global frequency planning.
