The [hrase "The most robust low-speed powerline technology uses DCSK technology available from Yitran Communications" is untrue thhis is old technology surpassed by EU initiatives such as PRIME. —Preceding unsigned comment added by 63.88.64.5 (talk) 13:55, 9 July 2009 (UTC)
Frankly, such statements should not be appearing in Wikipedia in the first place. The only suitable similiar statement I would should be things such as "this [reliable independant survey] judged this [make and model] to provide best speed, reliability etc". Statements such as the above are stating as fact things will always be open to argument, and generally come over as something which has been written by a biast author.

The introduction is now very clearly disambiguating DC from AC, smart grid applicable from broadband standards, but this does require a separate HomePlug Green PHY article and probably more redirects like IEEE 1905.1 and IEEE 1905 (both of which should currently redirect to IEEE P1905 as the standard is still in the process).
Perhaps two different articles should describe PLC for short haul which is what the IEEE 1901 standard covers, and the longer haul technologies still in R&D like E-line from corridor.biz which supposedly compete with fibre over 1km and between transformers? — Preceding unsigned comment added by 76.11.94.143 (talk) 18:22, 6 October 2012 (UTC)
I think the technology section should describe "what" the technology is rather than "who" makes it. We can refer the reader to the PLC manufacturer's page for this type of information. --DavidDHaynes 17:48, 15 November 2007 (UTC)
An effort needs to be made to sort out the standards and organize them by the technology they attempt to address. Perhaps we should combine the Technology and Standards sections into a single section. Thoughts? --DavidDHaynes 18:07, 15 November 2007 (UTC)
It may be unreasonable to attempt to list all of the deployments. Many of the BPL citations in the current article were perhaps newsworthy at one time, but not of much interest today. To balance it out and attempt to cite every deployment for the other technologies would swamp the article, since they continue at a pace of about one a week. BPL deployments are newsworthy because they are new, novel, and rare. Does anyone have an idea on what to do about the growing list of deployments?--DavidDHaynes 17:59, 15 November 2007 (UTC)
The link "all BPL deployments in the US" only includes a few implementations, notably not the large (though still piloting) Cincinnati implementation.
What are the dangers of BPL to the ham radio comunites?
While the above comments are appropriate to HF-BPL, microwave-BPL known as E-Line has been shown not to have these problems. It has multi-Gbps capacity and doesn't cause the interference devastation of previous methods. In addition, by using existing infrastructure, the powerline, it circumvents the expense and delays of stringing ariel fiber and the attendant pole "make-ready" fees. Even with periodic amplification, very high capacity installations can be achieved at approximately one-tenth the cost of aeriel fiber. Furthermore, each amplification site is potentially a location for placement of a user-access antenna as part of a large distributed antenna system. Expensive optical/electrical & electro/optical conversion equipment is not required at each drop point. Such a system, composed of line mounted antennas, ~15 meters above ground, can effectively provide extremely high capacity services for mobile as well as fixed end users, even those in rural environments.

since this is an encyclopedia article, wouldn´t it be reasonable to expose not only benefits but also potential problems? This may include a possible bigger cost, and a littler SNR.
Doesn't this technology make AC power "dirty" for sensitive electronic devices? -- Beland 21:09, 17 August 2007 (UTC)
The 50 or 60 Hz power is not a pure sinewave anyway. Many applications contribute some noise to the powerline -- its just in this case the contribution is intentional. There are FCC and IEC regulations to limit the emissions at the important parts of the spectrum. As long as the electronic device has a proper power supply, it shouldn't be affected. In fact, most of our PC's have switch mode power supplies. An office building full of PC's can contribute significant noise to the powerline. (Ironical isn't it!)--DavidDHaynes 19:26, 29 August 2007 (UTC)
The Main article link for the Home Control section should link to Home automation article instead of X10. If there are no objections I'll make the change. Kinema 06:11, 20 May 2007 (UTC)

This article does a good job discussing systems that send data over conductors originally intended to carry power.
However, it fails to mention systems that send power over conductors originally intended to carry data (such as Power over Ethernet, AS-Interface, telephone line, etc.). Such systems run at less than 50 V, because various organizations have ruled that 50 V is a "safe" voltage (extra-low voltage).
Should another section be added to this article discussing such systems? Or am I overlooking some other article that already discusses such systems? --68.0.124.33 (talk) 14:21, 17 July 2008 (UTC)
That sounds the inverse of this: sending power over lines intended primarily for communication. Should be mentioned as a sort of inverse but very briefly. W Nowicki (talk) 23:53, 22 July 2011 (UTC)
I enjoyed reading this article. My understanding is that it's possible to have a network of various home attached by PLC. Is anyone interested in making a diagram? How about one for North America? Here's my attempt for my neighborhood.

The Checksection template has been inserted into this section as the last sentence of the last paragraph contains a word implying NPOV violation. PatrickDunfordNZ (talk) 02:55, 12 May 2009 (UTC)
I moved the previous E-Line information out of the High-Frequency section, the previous upper limit, and added a new section for Power line communication above 100 MHz. As the characteristics, technology and applications are completely different from the other types, this seems warranted. It still needs cleanup (citations converted to references etc). N6gn (talk) 14:06, 29 July 2009 (UTC)
Lots of material in this, but much is overlapping and confusing. One problem is that broadband has lost its technical meaning. I think often it means Internet access, and it seems in theory possible to use power lines for Internet access (although one would need citations for actual providers). I think that is what most politicians mean when they say "Broadband"? Then there is using power lines as a LAN within a home. Might be called "Broadband" too if video is sent for example. These both seem different than the "Smart Grid" idea, which might include the power companies to send data on the lines themselves. These seem all mixed together.

DLC uses existing electrical distribution network in the medium voltage (MV) — i.e., 11 kV, Low Voltage (LV) as well as building voltages. It is very similar to the powerline carrier. DLC uses narrowband powerline communication frequency range of 9 to 500 kHz with data rate up to 576 kbit/s. DLC is suitable (even in very large networks) for multiple realtime energy management applications. It can be implemented under REMPLI System as well as SCADA, AMR and Power Quality Monitoring System. DLC complies with the following standards: EN 50065 (CENELEC), IEC 61000-3 and FCC Part 15 Subpart B.
Radio users may experience some interference to their systems when in the near proximity of overhead power lines. For two way radio systems utilizing digital schemas, such as the P25 systems, this may appear as loss of received signal caused by the radio's front end (desensitising the receiver). For analog radios the interference appears as a buzzing sound eminating from the radio's speaker. With external inductive or capacitive coupling, a distance more than 15 km can be achieved over a medium voltage network. On low voltage networks, a direct connection can be made since the DLC has a built-in capacitive coupler. This allows end-end communications from substation to the customer premises without repeaters.
The latest DLC systems significantly improve upon and differ from other powerline communication segments. DLC is mainly useful for last-mile and backhaul instrastucture that can be integrated with corporate wide area networks (WANs) via TCP/IP, serial communication or leased-line modem to cater for multi-services realtime energy management systems.
More recently, narrowband PLC communications techniques have also started to include implementations of more sophisticated communication technologies like OFDM, that were till date used in broadband domain. PRIME is one such system that operates within CENELEC A band and uses OFDM as the technology at physical layer to provide data rates of up to 128 kbit/s. The PRIME Alliance is an industrial consortium that is putting forth this open specifications of physical and MAC layers and allowing for utilities to pick solutions from different vendors.
As per WP:ENGVAR, we should stick to one variety of English per article. It seems to use British style dates and some words, but "power line" seems more American than "the mains" would be. Does anyone have any strong thoughts either way? W Nowicki (talk) 17:13, 24 July 2011 (UTC)
Thanks for the humor (humour??) and good point (eh?). I did a pass a couple days ago, but there is much more to be cleaned up. I got distracted (also worked on IEEE 1901 a bit). Am I heading in the right direction? For example, using citations instead of inline links, trying to form a historical narrative, etc. W Nowicki (talk) 23:36, 24 July 2011 (UTC)
I suggest we split the broadband-over-power-line material out to its own article; it's notable in its own right and gets into details that bog down this overview. --Wtshymanski (talk) 20:15, 21 November 2011 (UTC)
We have since created the Broadband over power lines article. -- Beland (talk) 21:15, 15 November 2016 (UTC)
PLC carrier repeating station is a very small stub on a topic with little independant notability; it should be merged to this article to give it context. --Wtshymanski (talk) 21:34, 28 November 2011 (UTC)

This article needs a strong dose of WP:FIXIT. It needs WP:COPYEDIT. The first sentence of the article doesn't even define it properly: "PLC is a communication protocol that uses electrical wiring to simultaneously carry both data, and Alternating Current (AC) electric power transmission or electric power distribution" It's not restricted to AC. A better definition is "PLC is a communication technology that enables the transfer of data over power cables." Large amounts of WP:ORIGINAL needs referencing or deletion. It's also out of date: where's Insteon?
The article is rather rambling and I propose to organise it as
A larger goal is to eliminate some of the overlap between this article and G.hn, Broadband over power lines, Broadband, HomePlug, HomePNA, IEEE 1901, PLCBUS, Universal Powerline Association, X10 (industry standard), X10 Firecracker, Z-Wave, ZigBee, and IEC 61334 etc. etc.
If you wish to contribute to this project, please comment here (rather than on my talk page or reverting) or edit constructively. --Cornellier (talk) 04:38, 20 February 2016 (UTC)
Some context about the adoption rate of this technology would be extremely helpful. -- Beland (talk) 21:20, 15 November 2016 (UTC)
