PRIME is a specification for narrow band powerline communication. Power-line communication uses power lines as transmission media. PRIME is an acronym for "PoweRline Intelligent Metering Evolution". PRIME was conceived in 2007.〔Berganza, Inigo, Alberto Sendin, and Javier Arriola. (PRIME: Powerline intelligent metering evolution ). CIRED Seminar. 2008.〕 First publications date back to 2008. In 2009 multi-vendor interoperability was demonstrated and the PRIME Alliance launched. The PRIME Alliance has interoperability tests in place, which are carried out by multiple accredited test laboratories. Currently, the tests have been passed by over 40 products.〔(PRIME Certified Products )〕 Most popular usage of PRIME is in AMI. According to PRIME Alliance more than 5 million meters in 9 countries are deployed.〔(Prime Alliance News Letter ). December 2014.〕 ==Specification Overview== The PRIME specification〔(Narrowband orthogonal frequency division multiplexing power line communication transceivers for PRIME networks ). International Telecommunication Union. 2012.〕 is structured into Physical Layer, MAC Layer and Convergence Layer. For operations and control, a "Management Plane is specified". 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PRIME (PLC)」の詳細全文を読む スポンサード リンク
