HomePlug
HomePlug is the family name for various power line communications specifications under the HomePlug designation, each with unique capabilities and compatibility with other HomePlug specifications. Some HomePlug specifications target broadband applications. For instance in-home distribution of low data rate IPTV, gaming, and Internet content, while others focus on low power, low throughput and extended operating temperatures for applications such as smart power meters and in-home communications between electric systems and appliances. All of the HomePlug specifications were developed by the HomePlug Powerline Alliance, which also owns the HomePlug trademark. On 18 October 2016 the HomePlug Alliance announced that all of its specifications would be put into the public domain and that other organizations would be taking on future activities relating to deployment of the existing technologies. There was no mention in the announcement of any further technology development within the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Line Communication
Power-line communication (PLC) is the carrying of data on a conductor (the ''power-line carrier'') that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. A wide range of power-line communication technologies are needed for different applications, ranging from home automation to Internet access, which is often called broadband over power lines (BPL). Most PLC technologies limit themselves to one type of wires (such as premises wiring within a single building), but some can cross between two levels (for example, both the distribution network and premises wiring). Typically transformers prevent propagating the signal, which requires multiple technologies to form very large networks. Various data rates and frequencies are used in different situations. A number of difficult technical problems are common between wireless and power-line communication, notably those of spread spectrum radio signals operating in a crowded envi ...

Advanced Metering Infrastructure
A smart meter is an Electronics, electronic device that records information—such as consumption of electric energy, voltage levels, current, and power factor—and Telemetering, communicates the information to the consumer and Public utility, electricity suppliers. Advanced metering infrastructure (AMI) differs from automatic meter reading (AMR) in that it enables two-way communication between the meter and the supplier. Description The term ''smart meter'' often refers to an electricity meter, but it also may mean a device measuring natural gas, water or district heating consumption. More generally, a smart meter is an Electronics, electronic device that records information such as consumption of electric energy, voltage levels, current, and power factor. Smart meters Telemetering, communicate the information to the consumer for greater clarity of consumption behavior, and Public utility, electricity suppliers for system monitoring and customer billing. Smart meters typicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qualcomm Atheros
Atheros Communications, Inc., was an American computer networking company independently active from 1998 to 2011. It produced semiconductor chips for network communications, particularly wireless chipsets. The company was founded under the name T-Span Systems in 1998 by experts in signal processing and VLSI design from Stanford University, the University of California, Berkeley, and private industry. The company was renamed Atheros Communications in 2000 and it completed an initial public offering in February 2004, trading on the NASDAQ under the symbol ATHR. On January 5, 2011, it was announced that Qualcomm had agreed to a takeover of the company for a valuation of US$3.7 billion. When the acquisition was completed on May 24, 2011, Atheros became a subsidiary of Qualcomm operating under the name Qualcomm Atheros. Qualcomm Atheros chipsets for the IEEE 802.11 standard of wireless networking are used by over 30 different wireless device manufacturers. History T-Span Systems ...

IEEE 1901
IEEE 1901 is a standard for high-speed (up to 500 Mbit/s at the physical layer) communication devices via electric power lines, often called broadband over power lines (BPL). The standard uses transmission frequencies below 100 MHz. This standard is usable by all classes of BPL devices, including BPL devices used for the connection (<1500m to the premises) to services as well as BPL devices used within buildings for s, smart energy applications, transportation platforms (vehicle), and other data distribution applications (<100m between devices). The IEEE 1901 Standard, established in 2010, set ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IEEE P1905
IEEE 1905.1 is an IEEE standard which defines a network enabler for home networking supporting both wireless and wireline technologies: IEEE 802.11 (marketed under the Wi-Fi trademark), IEEE 1901 (HomePlug, HD-PLC) power-line networking, IEEE 802.3 Ethernet and Multimedia over Coax (MoCA). The IEEE P1905.1 working group had its first meeting in December 2010 to begin development of convergence digital home network specifications. Around 30 organizations participated in the group and achieved approval of the draft P1905.1 standard in January 2013 with final approval and publication by IEEE-SA in April 2013. The IEEE 1905.1 Standard Working Group is sponsored by the IEEE power-line communication standards committee (PLCSC). From about 2013 to 2015, a program called nVoy certified related products. It is not to be confused with the Pogo Mobile and nVoy device of the same name nor various networked devices named Envoy. Vendors (such as Qualcomm and Broadcom) endorsed the certifi ...
