The mission of the Consumer Technology Association (CTA)® is to help innovators of all sizes grow their business. Technology is about changing people’s lives for the better. It’s about ideas, large and small, that keep us connected, that help us move and that spark even bigger ideas.

We rank the CTA suite in the middle tier of our advocacy priorities at the moment but action in the CTA suite is picked up in our tracking system. We simply note the commenting opportunity here.

Open for review:

CTA 709.8 Open Data Communication in Building Automation, Controls and Building Management – Control Network Protocol Specification – Part 8: Control Network Protocol/High Definition Power Line Channel Specification (CNP/HD-PLC)

This standard specifies a communication protocol for networked control systems. The protocol provides peer-to-peer communication for networked control using web-services. The standard describes services in layer 1 and layer 2. The layer 1 (physical layer) describes the MAC sub-layer interface to the physical layer. The layer 2 (data link layer), as described in ANSI/CTA 709.1, is integrated in UDP/IP communication using IPv4 and IPv6 protocols.

CTA 709.9 Open Data Communication in Building Automation, Controls and Building Management – Control Network Protocol Specification – Part 9: Control Network Protocol/Wireless Communication in ISM Bands (LON-ISM-RF)

This standard specifies a new, high-speed, long-distance RF media to the current 709 LON standards. The ISM-RF (Industry, Science, Medicine Radio Frequency) transceiver uses unlicensed RF bands and are specific for EU, North America, and other regions through a software-selectable configuration property. This new standard will provide full interoperability and backwards compatibility with any of the current CTA-709 media types using a standard LON-to-LON router. This new media type is suitable for building and home applications as well as smart city and campus applications. It utilizes a meshing software algorithm to ensure broad coverage over long distance without degrading performance. With over 1MB/sec data rates, the primary use cases are for data collection, device monitoring, and control networks where wired devices are not suitable.
