To wrap up some of the information here, from reading the other submissions on this site, I suggest that it could be concluded that ZigBee is the only totally suitable solution for ERA / SRSM local comms and nothing I have seen so far suggests otherwise.
Here are some of the reasons; 1. It is the ONLY technology being considered that is currently an open standard, with multiple independent implementations of silicon and software stacks in the market and in products today. 2. It is the ONLY technology considered that is designed for and has already been used for both local communications and last mile AMR communications. 3. It has a defined and proven interoperable Smart Energy application profile specifically for Smart Metering, with 15 end products already certified by the ZigBee Alliance, including a number of meters, in home displays, thermostats and load controllers. 4. There is real competition and innovation among many of the 19 ZigBee compliant platforms, which is driving performance up and cost down, and making it future proof, which is a goal of the ERA. 5. It has a very strong security mechanism, starting with AES 128-bit encryption in many cases implemented in hardware, right through to rolling network keys, application link keys and public key encryption with digital certificates, all part of the ZigBee PRO and Smart Energy specifications. 6. Operating at 2.4GHz, it has 16 channels available which can be used to structure and separate networks, increase available bandwidth and secure networks against interference. 7. It is based on the IEEE 802.15.4 standard for MAC and PHY, solidifying it as a standard platform. 8. It is supported by some of the largest meter manufacturers in the World. |

Dear all,
Obviously, I consider the "summary" and conclusion from David Egan as a little premature. Or are we all wasting our time and money in this project if the answer is so clear? What happened to the hype of ZigBee in the telecommunication industry 2 years ago? Why did the massive use of ZigBee chips on GSM SIM cards did not happen? Wasn't there also the statement that interference and RF overall would not be an issue? Why did practically all industrial users moved away from ZigBee? Why do we have competing efforts in this space from ISA SP100, Wireless Hart, and the IETF (!)? Which Promoters have left ZigBee? Which other industry is left *potentially* using ZigBee? Isn't "ZigBee" largely referencing proprietary use of IEEE802.15.4 to appear large and healthy? Does Ember or the ZigBee alliance guarantee there won't be interference issues from WLAN? Also not in the future? Really ignore the simulations that were done by the founder of Ember? Would you believe it's safe for your daugther to ride a bike on a three-lane freeway if someone explains you how this *could* be done? Or would you rather tell her to go and use the bike path on the side? Who is ready to bet his career and say that 2.4 GHz will not suffer heavily from interference? Was there ever a ZigBee version that is backwardward compatible to the previous version? Could we afford to swap the ZigBee stack every year? Did anyone look at the level of complexity imposed by ZigBee's security "solution"? What will be the cost impact on suppliers and device manufacturers over the product's lifetime. Who owns IP in the ZigBee radio, stack, and the "Smart Energy" profile? I guess I could keep adding questions. However, I'd rather suggest we all continue to work in the project in a systematic fashion. Cheers Bernd |

The ZigBee Alliance has just completed its first batch of certification of products for the ZigBee Smart Energy profile.
There are now 15 products of various sorts (meters, in-home-displays, thermostats, portals) now certified to the ZigBee Smart Energy profile, with a further 4 test and reference applications also certified. We anticipate that following this initial group, there will be many more certifications in 2008. The list of ZigBee Smart Energy certified products and companies can be found on the ZigBee.org web site here; http://www.zigbee.org/en/certification/certified_products_zse.asp |
