The HomePNA Alliance (formerly the Home Phoneline Networking Alliance, also known as HPNA) is an incorporated non-profit industry association of companies that develops and standardizes technology for home networking over the existing coaxial cables and telephone wiring within homes, so new wires do not need to be installed.
HomePNA was developed for entertainment applications such as IPTV which require good quality of service (QoS).
