HomePlug Powerline Alliance selects Yitran modem technology

Supplier News

The HomePlug Powerline Alliance announced the selection of Yitran Communications’ IT800 powerline modem technology (available through Glyn High-Tech Distribution) as the baseline technology for its HomePlug Command and Control specification.

Yitran designs and develops proprietary digital and mixed-signal integrated circuits such as the IT800D for power line communications, used in various applications including home automation and networking, energy management and AMR (Automatic Meter Reading), Internet appliances, and control applications over existing electrical infrastructure.

The IT800Dis a System on a Chip device that incorporates IT800 PHY with a microprocessor that runs Yitran's DLL (Data Link Layer) firmware. The IT800D provides all the benefits of Yitran's high performance DLL (Adaptive back-off CSMA/CA channel access, ACK/unACK services, retransmissions and more) on top the IT800 PHY. The IT800D is an ideal solution for a variety of products such as smart metering and home automation, where usage of the IT800D enables coexistence with other proprietary and standard solutions (based on Yitran’s IT800 PHY and DLL).

The competition for the HPCC baseline technology included worldwide companies, including prominent members of the HomePlug board of directors.

Nine companies from around the world responded to the Alliance’s open call for technology proponents. The criteria for comparing the technologies were based on a Market Requirements Document (MRD) developed by the member companies. Companies agreed on fair and unbiased testing procedures, and upon the outcome of field and laboratory tests, the number of proponents was reduced to three. After a bake-off, Yitran’s technology emerged as the clear choice for the HomePlug Command and Control baseline.

According to the Alliance’s standard process, the next steps include the formation of a Specification Working Group to build and refine the HomePlug Command & Control MAC/PHY technology, and the tasks of writing the specification to ensure that silicon companies all over the world can create HomePlug-compliant implementations.

The HomePlug BoD is expecting to ratify the specification in Q3/06.
