Neil, Thanks for the great info!     If or when Zigbee truly becomes globally accepted, will there still much of a role for TinyOS?     From: Neilh10 [mailto:[EMAIL PROTECTED] Sent: Thursday, February 17, 2005 6:28 PM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: RE: [Tinyos-users] TTX Publications   If by SNMS you mean the "Nucleus Network Management system" - the proposal seems to be to  help in stabilizing networks - visibility and testability in developer applications.    Zigbee was stated as being something that could co-exist with TinyOS.   I went to a ChipCon presentation two weeks ago were Zigbee Consortium had a slot. Also ChipCon has purchased Figure8 - a one-stop Zigbee provider.  They have an application interface where they simplify the problems the software developers has to what they want to turn on/off. Zigbee Consortium is proposing a number of application profiles - e.g. turning on a light bulb - Manufacturer X switch can talk to Manufacturer Y's light bulb. Zigbee Consortium are also proposing separate test houses (aka WiFi) to test inter operability, but also are going for open houses 'jam' sessions to determine what level of testing is needed for what level of inter-operability.   The conclusion I got was that Zigbee consortium is likely to over-hype the possibilities  - they are coming up with something behind closed doors, that is addressing some of the market gaps not covered by BlueTooth.   The major value the Zigbee Consortium aims to bring, that perhaps nobody else can bring is consumer brand management to low cost, short distance, low power wireless. Not a cheap or easily defined project. To get Zigbee certification, you have to pay for an annual membership fee, pay for the testing, and pay a per product marketing fee. Not cheap.   TinyOS as an open standard across multiple platforms - if it can stabilize and become ordinary  consumer friendly then it might start to work in Zigbee's space - but that seems unlikely. TinyOS umbrella may be were the technical problems are solved, and talked about as an engine for wireless reliability and interoperability .    Zigbee label may be that which the consumers recognize and understand - like they are starting to do with WiFi, BlueTooth etc.   If you want the public presentations of Zigbee and Figure8 I can forward them on.        Neil   ----- From: Jeff Thorn [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 17, 2005 12:18 PM To: [EMAIL PROTECTED] Subject: [Tinyos-users] TTX Publications Does anyone know if there will be any publications / documentation on what was discussed at the recent TinyOS Technology Exchange? I am particularly interested in the panel on the role of Zigbee. I would also like to learn more about SNMS. Thanks! Jeff
