discussing the transmission of data via power lines:
"The hunger for increased bandwidth is driving individuals, corporations, and organizations to seek new methods for delivering Internet service to customers. Many of these methods are well known: radio-frequency (or wireless) communications (such as the IEEE 802.11 Wireless LAN, Bluetooth, and the HomeRF and SWAP Protocols), infrared communications (IrDA), fiber-optic channels, high-speed telephone connections (such as DSL and ISDN or the more modern Home Phoneline Networking Alliance (HomePNA) system). One approach that is still receiving a cool reception in the United States is a highly discussed option in Europe and the rest of the world using the power grid as a delivery conduit for high-speed data communications. This paper provides a brief introduction to High-Speed Powerline Communications (HSPLC): the technologies, political struggles, and future look."
"XlO, the granddaddy of power line protocols, uses amplitude modulation to send binary information from a controller/transmitter to XlO modules that are plugged into a standard electrical outlet."
"In a nutshell, the problem is that HSPLC radiates electromagnetic energy off the power transmission lines. Depending on the data rate, signal frequencies of HSPLC can vary from 100 kHz to 30 MHz, a band of frequencies that is highly used for mobile, marine and aeronautical distress and calling, for time signals used by radio astronomers, by airports for civil defense communications - in short, a wide variety of critical communications."
"Additionally, there is massive resistance by the current users of the proposed frequency band (coming from civil defense organizations, military, scientific (astronomy) organizations - everyone who has a stake in the outcome)."
"Powerline carrier communications is here to stay. It may be limited to a local area network within the home or office, or it may become another medium like telephone modem communications, but it will be used in the future. The only real obstacle to its full development is the lack of a standard around which the entire industry can rally. The future holds the answer."
This is what the whistleblower Dr. John Hall had to say about this subject:“... you can listen to the insides of a home with the power lines, i talk to connections that I have that are in our city public service, controls the electric power in San Antonio, they actually talk to each other via the power line. You can hook up to a power line talk from one station [to another], I’m not talking just data I’m talking vocal communication. They can communicate to each other over the power line,… and when I talked to him I said what about listening inside a home, he did say that the FBI occasionally does come to them with a warrant to be able to listen in to a home through the power lines. Explained to me the little circular hole in your power plug that we all refer to as a ground, it's not actually a ground it’s a return. And if you look at the power lines on the poles you’ll have two uppers and one lower, the one lower is the return. And it can be adjusted to where the grid in your home actually picks up your spoken word, and it returns through the return for anybody to listen to.”
This is what a former CIA Director had to say related to the subject:More and more personal and household devices are connecting to the internet, from your television to your car navigation systems to your light switches. CIA Director David Petraeus cannot wait to spy on you through them.
Earlier this month, Petraeus mused about the emergence of an “Internet of Things” — that is, wired devices — at a summit for In-Q-Tel, the CIA’s venture capital firm. “‘Transformational’ is an overused word, but I do believe it properly applies to these technologies,” Petraeus enthused, “particularly to their effect on clandestine tradecraft."
