HPN meaning in Computing ?

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 was developed for entertainment applications such as IPTV which require good quality of service (QoS). HomePNA 3.1 uses frequencies above those used for digital subscriber line and analog voice calls over phone wires and below those used for broadcast and direct broadcast satellite TV over coax, so it can coexist with those services on the same wires.

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.

HomePNA promoter companies are AT&T Inc., Technicolor SA, Pace plc, Sigma Designs, Motorola, Cisco Systems, Sunrise Telecom and K-Micro.

Devices that use HPNA technology as part of whole-home multi-media content products include Advanced Digital Broadcast, Inneoquest and NetSys.

Alternatives to HomePNA include: Power line communication, Wi-Fi, data over cable, and multimedia over coax.
