新協議驅動住宅照明無線控制

　　新協議和開放標準正在出現，這些技術有助于推動家庭自動化中無線鏈路的數量并降低成本。在住宅環境中控制照明系統提供了更多的能源成本可控性，將照明連接到可以通過智能手機、平板電腦和PCs.等設備訪問的中央網關。

　　但是圍繞不同的無線技術仍然存在成本和干擾的問題。雖然WiFi是一種開放的標準，在家庭中很流行，它可以承載多媒體數據，但在住宅控制應用中，比如照明，它的數量并沒有大幅度增長。

　　其他2.4 GHz的技術，如ZigBee，已被用于家庭自動化設備和網狀網絡的方法越來越流行的連接在家里的元素，特別是照明系統的控制。其他技術，如Sigma Designs的Z-Wave無線協議和EnOcean也出現在較低的非授權頻段在315兆赫和868兆赫。

　　德國的無線專家EnOcean現在看到它的無線短數據包協議作為國際標準化組織（ISO）標準。

　　The ISO/IEC 14543-3-10 standard for Home Electronic Systems （HES） uses the EnOcean protocol and the first three layers to provide a consistent basis for the development of ultra-low power wireless controllers. This move to an open standard will allow silicon vendors and module makers to develop gateways that will connect to sensors and controllers that use the EnOcean technology. By creating an open standard for such designs， EnOcean sees an increase in volume and a reduction in cost to further drive the technology into the home.

　　The EnOcean technology has been developed over the last ten years and uses regulated frequency ranges approved for pulsed signals at 868.3 MHz or 315 MHz for worldwide use coupled with a prearranged transmitter-to-receiver assignment with four billion fixed code numbers to provide this reliability， which is now within an open standard environment. The radio uses ASK and low data rates of 125 Kbit/s to keep the costs down， along with short telegrams that are sent at random to avoid collisions.
