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 first four bytes of each packet are a preamble to measure the channel’s current condition. From Wikipedia, the free encyclopedia. IECknown as Distribution automation using distribution line carrier systemsis a standard for low-speed reliable power line communications by electricity meterswater meters and SCADA. Automatisation de la distribution a l’aide de systemes de communication a courants porteurs.

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.


Views Read Edit View history. The standard’s low speed is caused by the limited number of bits per power line cycle. List of International Electrotechnical Commission standards.

Take the smart route to manage medical device compliance. You may experience issues viewing this site in Internet Explorer 9, 10 or Each byte is collected into byte packets. This is followed iwc 38 bytes of data, and 3 byte-times of silence. 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, 61334- a management interface.

One tone is chosen for mark i. In multiphase power lines, a separate signal might be sent on ifc phase to speed up the transmission. Related standards use the physical layer e. The bytes from the low-layer packets are reformed into bytes for the higher layers.

BS EN 61334-6:2001, IEC 61334-6:2000

The faster, easier way to work with standards. The tones are chosen by utilities, not specified in the standard. The system should be able to adjust the receiving method on each byte packet. The silence and the preamble allow the receiver’s signal processing to measure the channel’s noise ratios.
