The standard’s low speed is caused by the limited number of bits per power line cycle. The faster, easier way to work with standards. This is followed by 38 bytes of data, and 3 byte-times of silence.

The silence and the preamble allow the receiver’s 16334-6 processing to measure the channel’s noise ratios. Find Similar Items This product falls into the following categories.

The higher link-layer strongly resembles HDLCexcept with a novel feature that allows selected stations to retransmit messages.

The physical layer synchronizes a small packet of tones to the zero-crossing of the power line’s voltage. Your basket is empty. Please download Chrome or Firefox iev view our browser tips.

For example, it lets a central controller read a unit’s signal to noise ratios, and set the bit that enables a station to retransmit weak stations. List of International Electrotechnical Commission standards.

The first four bytes of each packet are a preamble to measure the channel’s current condition. Take the smart route to manage medical device compliance. The most significant bits are sent first, unlike a conventional serial port. A-XDR encoding rule Status: We use cookies to make our website ifc to use and to better understand your needs.

One tone is chosen for mark i. From Wikipedia, the free encyclopedia. This page was last edited on 30 Marchat 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 63134-6, and a management ifc.

Depending on the oec 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. The standard permits each zero-crossing to convey 1, 2, 4 or 8 bits, with increased sensitivity to timing as the number of bits increases.

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. This website is best viewed with browser version of up to Microsoft Jec Explorer 8 or Firefox 3. Each byte is collected into byte packets.

The data from zero crossings should be collected into 8-bit bytes. 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.

Retrieved from ” https: In multiphase power lines, a separate signal might be sent on each phase to speed up the transmission. 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.
