The physical layer is adaptive. It is actually a series of standards describing the researched physical environment of power lines, a well-adapted physical layer, a workable low-power media access layer, and a management interface. One tone is chosen for mark i. In multiphase power lines, a separate signal might be sent on each phase to speed up the transmission. The frequencies are placed far enough apart that frequency-selective fading and narrow-band interference only blocks one of the frequencies, so the receiver can still recover all the data from the other frequency.

S-FSK spread frequency-shift keying is a modulation scheme that combines some of the advantages of classical spread-spectrum modulation immunity against narrow-band interference with some of the advantages of classical frequency-shift keying FSK is low complexity. The tones are chosen by utilities, not specified in the standard.

Depending on the signal to noise ratios, the bits can be recovered from the difference between the power of the mark and space tones, the power of the mark tones only, or the space tones only. Automatisation de la distribution a l’aide de systemes de communication a courants porteurs.

IECknown as Distribution automation using distribution line carrier systemsis a standard for low-speed reliable power line communications by electricity meterswater meters and SCADA. The bytes from the low-layer packets are reformed into bytes for the higher layers. The first four bytes of each packet are a preamble to measure the channel’s current condition. The most significant bits are sent first, unlike a conventional serial port. This is followed by 38 bytes of data, and 3 byte-times of silence.

The data from zero crossings should be collected into 8-bit bytes. A-XDR encoding rule Status: This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3.
