} <\/script>\r\n<\/div>\r\n<\/div>\n<p>Although the whole ZigBee ethos was to use minimal power &#8211; one year\u2019s operation from two AA cells has been quoted &#8211; it was not designed from the ground up to run from harvested energy. <\/p>\n<p>That said, Sheffield fabless chip firm Jennic has used its wireless microcontroller chip to demonstrate IEEE802.15.4, ZigBee and 6LoWPAN wireless sensor networks powered by vibrations, thermal gradients, light and RF energy. <\/p>\n<p>\u201cZigBee Green Power, when completed, will connect devices using existing energy harvesting techniques,\u201d ZigBee Alliance spokesman Kevin Schader told EW. <\/p>\n<p>His Alliance sees ZigBee\u2019s existing user base, largely open nature, and broad applicability as tipping the balance in its favour. <\/p>\n<p>\u201cSince ZigBee is a global, open standard using the internationally available 2.4GHz spectrum, we do not see any competition from proprietary technologies,\u201d said Schader. \u201cIn addition, ZigBee has a variety of applications, or public application profiles that provide services specifically targeted for energy management, health care, home automation, commercial building automation and telecom services.\u201d <\/p>\n<p>Details of ZigBee Green Power have yet to be published so specific information on how much energy will be needed for each device is not yet available, but projections are expected by the end of the year. <\/p>\n<p>EnOcean technology was always intended to run from scavenged power. <\/p>\n<p>From 50\u00b5W a standard EnOcean wireless module can transmit 30m indoors and 300m in open space. <\/p>\n<p>Duty cycle is 1% and data at 125kbit\/s is sent in 1ms \u2018telegrams\u2019. <\/p>\n<p>In addition to existing self-generating light switches and other modules, sensor profiles will be specified by its Alliance for interoperability. <\/p>\n<p>\u201cOur technical working group has now ratified the first EnOcean Alliance specification and it will be launching worldwide at the start of November,\u201d EnOcean Alliance chairman Graham Martin told EW. \u201cThe EnOcean Alliance is also working within the IEC to have the EnOcean Standard adopted, ratified and released as a full international standard.\u201d <\/p>\n<p>The ZigBee Alliance dismisses \u201cproprietary technologies\u201d; so what is the EnOcean Alliance view of the ZigBee Alliance attempts to set up an energy harvested standard?<\/p>\n<p>\u201cWe have taken note of the ZigBee Alliance announcement that it plans to develop ZigBee Green Power.\u00a0 We are delighted to hear that now also ZigBee sees the potential of wireless and batteryless energy harvesting solutions,\u201d said Markus Brehler CEO and founder of EnOcean, the firm behind the technology. \u201cAs soon as ZigBee\u2019s planned developments reach the market we will of course have to clarify the patent situation as we already have registered multiple patent families in the area of energy harvesting wireless technology.\u201d\u00a0\u00a0 <\/p>\n","protected":false},"excerpt":{"rendered":"<p>The ZigBee Alliance and the EnOcean Alliance are pitching for international standards recognition for harvested-energy wireless nodes, with different proposals.<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[12655],"tags":[14828,13811,14093],"class_list":["post-416761","post","type-post","status-publish","format-standard","hentry","category-legislation","tag-energy-harvesting","tag-enocean","tag-zigbee"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v26.7 (Yoast SEO v27.2) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>EnOcean and ZigBee vie for energy harvesting market | Electronics Weekly<\/title>\n<meta name=\"description\" content=\"The ZigBee Alliance and the EnOcean Alliance are pitching for international standards recognition for harvested-energy wireless nodes, with different proposals.\" \/>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.electronicsweekly.com\/news\/design\/legislation\/enocean-and-zigbee-vie-for-energy-harvesting-market-2009-09\/\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:title\" content=\"EnOcean and ZigBee vie for energy harvesting market | Electronics Weekly\" \/>\n<meta name=\"twitter:description\" content=\"The ZigBee Alliance and the EnOcean Alliance are pitching for international standards recognition for harvested-energy wireless nodes, with different proposals.\" \/>\n<meta name=\"twitter:creator\" content=\"@ElectronicsNews\" \/>\n<meta name=\"twitter:site\" content=\"@ElectronicsNews\" \/>\n<meta name=\"twitter:label1\" content=\"Written by\" \/>\n\t<meta name=\"twitter:data1\" content=\"Steve Bush\" \/>\n\t<meta name=\"twitter:label2\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data2\" content=\"3 minutes\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"Article\",\"@id\":\"https:\/\/www.electronicsweekly.com\/news\/design\/legislation\/enocean-and-zigbee-vie-for-energy-harvesting-market-2009-09\/#article\",\"isPartOf\":{\"@id\":\"https:\/\/www.electronicsweekly.com\/news\/design\/legislation\/enocean-and-zigbee-vie-for-energy-harvesting-market-2009-09\/\"},\"author\":{\"name\":\"Steve Bush\",\"@id\":\"https:\/\/www.electronicsweekly.com\/#\/schema\/person\/6b872697fe5e17abda1e967b9d09c1bd\"},\"headline\":\"EnOcean and ZigBee vie for energy harvesting market\",\"datePublished\":\"2009-09-18T10:38:00+00:00\",\"mainEntityOfPage\":{\"@id\":\"https:\/\/www.electronicsweekly.com\/news\/design\/legislation\/enocean-and-zigbee-vie-for-energy-harvesting-market-2009-09\/\"},\"wordCount\":521,\"commentCount\":0,\"keywords\":[\"Energy Harvesting\",\"EnOcean\",\"Zigbee\"],\"articleSection\":[\"Legislation &amp;
