The HomePNA (Home Phoneline Networking Alliance) seeks to establish standards for Home Networking over regular coax and phone lines within the home - for compatibility between telecom, computer and network products. Home PNA (also known as '''HPNA''') is an incorporated non-profit association of more than 150 companies, including the founding companies 2Wire , Motorola , CopperGate , AT&T , Conexant , Sunrise . Home Phoneline Networking Alliance does not enforce standards; it provides advice to the International Telecommunication Union (ITU) which is a standards body. OVERVIEW HPNA as an entity does not manufacture any products, though its members do. However, it endorses products as Home Phoneline Network Certified™. The current version of their Home Phoneline Network Certified™ specifications is 3.1 (after 2006 it is referred to as HomePNA 3.1). ''HomePNA 1.0'' technology was developed by Tut Systems, and ''HomePNA 2.0'' was developed by Epigram, Inc. who continue to play a developmental role. ''HomePNA 3.0'' was developed by Broadcom and Coppergate solutions {Link without Title} . ''HomePNA 2.0'' received approval by the ITU as a global standard (Phoneline Networking Transceivers) known as Recommendation G.9951, G.9952 and G.9953. ''HomePNA 3.0 and 3.1'' received approval by the ITU as a global standard (Phoneline Networking Transceivers) known as Recommendation G.9954 (02/05) and G.9954 (01/07) respectively. ''HomePNA'' is a relatively new technology, which allows you to network your home computers much like a LAN using your existing telephone wiring. Internet access can be shared among several computers with or without a Router . Computers can access each other’s peripherals like printers and storage devices as well as the ability to play multiplayer games. ''HomePNA'' uses frequencies different from voice or fax calls while conducting data across the phone line. Coaxial cables are included in the HomePNA 3.1 standard to increase the networking capabilities and overcome some limitations of phone jack location. It's not clear if this part of HomePNA 3.1 specification will be included in ITU G.9954 (01/07) or in any specification another standard body or will remain available only to HomePNA members. REQUIREMENTS The Requirements for HomePNA 3.0 are: #Telephone jacks spawned from a single phone line (the phone line does not have to be active). Almost 99% of home telephone wiring in North America works with HomePNA 3.0. #Hardware approved by the Home Phone Networking Alliance. Generally, this applies to standard hardware such as network cards converting Digital to Analog and vice versa, but many brands of Routers , software, ethernet bridges and USB adaptors offer the Home Phoneline Network Certified™ versions. Some PCs are prefitted with the Home Phone Networking Alliance approved adaptors. The average consumer normally needs only a certified network card. ADVANTAGES Some advantages of HomePNA 3.0 are:
DISADVANTAGES Some disadvantages of HomePNA 3.0 are:
