The HomePNA Alliance 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 does not manufacture products, although its members do. HomePNA creates industry specifications which it then standardizes under the International Telecommunication Union (ITU) standards body. The HomePNA Alliance, tests implementations, and certifies products if they pass.
