The technology is standardized and promoted by the Home Phoneline Networking Alliance or HomePNA or HPNA.

Hardware approved by the Home Phone Networking Alliance. Generally these are all regular hardware such as network cards converting Digital to Analogue and vice versa but the list is getting bigger with many brands of Routers, Software, ISPs, Ethernet bridges and USB adaptors offering Home Phoneline Network Certified versions. Some PCs are even prefitted with the Home Phone Networking Alliance approved adaptors. The average consumer usually needs only network cards.
