Editing HomePlug (section)

==Interoperability==
HomePlug AV, GP and AV2 are fully interoperable, and will also interoperate with IEEE 1901 devices. HomePlug 1.0 devices do not interoperate with HomePlug AV devices. Although it is technically possible to achieve such backward compatibility, doing so is not economically feasible because of the high cost of circuitry that would have to support different [[forward error correction]] (FEC) techniques and feature sets.<ref>[http://www.edn.com/index.asp?layout=article&articleid=CA6558480 EDN] {{Webarchive|url=https://web.archive.org/web/20070202212526/http://www.edn.com/index.asp?layout=article |date=2007-02-02 }}, Voices: Intellon's Mark Hazen on the HomePlug AV powerline-networking alternative</ref>

HomePlug devices will not interoperate with devices that employ other powerline technologies, such as [[Universal Powerline Association]] (UPA), [[HD-PLC]], or [[G.hn]]. In the case of G.hn, it was deemed prohibitively expensive to implement both HomePlug's [[turbo coding]] [[forward error correction]] and G.hn's [[low-density parity-check code]].<ref>{{Cite news |title= Debate breaks out over home net standards |author= Rick Merritt |work= EE Times |date= March 25, 2009 |url= http://www.eetimes.com/document.asp?doc_id=1170652 |access-date= December 23, 2013 }}</ref> However, IEEE 1901 allows co-existence within the same deployment of both HomePlug AV and [[HD-PLC]] via its Inter-System Protocol (ISP). G.hn also supports the ISP.

HomePlug devices are not compatible with certain power strips, [[surge protector]]s, and [[Uninterruptible power supply|uninterruptible power supplies]] incorporating filters, which block the high-frequency signal. In such cases, the installer must plug devices directly into building electrical receptacles.<ref>{{cite web|title=Powerline Networking Adapters: User Manual|url=http://en-us-support.belkin.com/app/answers/detail/a_id/839/kw/F5D4073|access-date=16 September 2012|author=Belkin|page=4|format=PDF|year=2008}}{{Dead link|date=August 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> If a spare power point is not available, a double adapter can be used in many cases with the incompatible device on one side and the HomePlug device on the other.
