　　新協(xié)議驅(qū)動(dòng)住宅照明無線控制

　　新協(xié)議和開放標(biāo)準(zhǔn)正在出現(xiàn)，這些技術(shù)有助于推動(dòng)家庭自動(dòng)化中無線鏈路的數(shù)量并降低成本。在住宅環(huán)境中控制照明系統(tǒng)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(jī)、平板電腦和PCs.等設(shè)備訪問的中央網(wǎng)關(guān)。

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

　　其他2.4 GHz的技術(shù)，如ZigBee，已被用于家庭自動(dòng)化設(shè)備和網(wǎng)狀網(wǎng)絡(luò)的方法越來越流行的連接在家里的元素，特別是照明系統(tǒng)的控制。其他技術(shù)，如Sigma Designs的Z-Wave無線協(xié)議和EnOcean也出現(xiàn)在較低的非授權(quán)頻段在315兆赫和868兆赫。

　　德國的無線專家EnOcean現(xiàn)在看到它的無線短數(shù)據(jù)包協(xié)議作為國際標(biāo)準(zhǔn)化組織（ISO）標(biāo)準(zhǔn)。

　　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.
