Talk:Z-Wave
From Wikipedia, the free encyclopedia
Hi guys, and thanks for the good information on Z-wave. There is one item that I am having trouble understanding. The Radio specifics section says:
Z-wave units can be in power-save mode and only be active 0.1% of the time, thus reducing power consumption dramatically.
But then the Topology section says:
In order for Z-wave units to be able to route unsolicited messages, they cannot be in sleep mode.
So even though the protocol allows for sleep mode, sleep mode is not used in actual products. Is this correct? Perhaps a clarification of this point would be useful.
Thanks again!

- When units are in sleep mode, they cannot relay messages. So you cannot have re-routing of messages in a network where all nodes are sleeping. Typically, sensor units with very stringent power requirements would sleep most of the time, wake up periodically and submit data. If the recipient is multiple hops away, there needs to be non-sleeping nodes along the path to the receiver. Snielsen 21:44, 25 July 2006 (UTC)

[edit] The range doesn't make sense.
Regarding range, the article includes this line:
"Range: Approx. 100 feet (30 meters indoors) assuming "open air" conditions, with greatly reduced range in normal situations."
So the range is 100 feet assuming "open air" conditions, and "30 meters indoors". But 100 feet is approximately 30 metres and the indoor range should be considerably less than the open air range, so this doesn't make sense.
This is also not good style. The text in parenthesis should be either a translation into metric, or a statement of the range indoors vs. outdoors. It shouldn't be both.
I will edit the article to remove this contradiction, but someone who knows more than my about this topic should fill in the indoor range.

- I agree. I might add that it is almost impossible to generalize about the indoor range of such units. I have seen specs mentioning 100 feet indoors. And I have seen real life deviations of more than 50%. Snielsen 21:44, 25 July 2006 (UTC)
[edit] Z-Wave versus ZigBee
There should probably be a Z-Wave versus ZigBee comparison section. They both begin with the letter 'Z' and people may think they are one and the same, or Z-Wave a derivative of ZigBee, which doesn't seem to be the case. --Ray (talk) 13:48, 12 December 2007 (UTC)
[edit] Z-Wave product list
I would like to see an article/list of products that implement Z-Wave, maybe manufacturer link. Or is this Googles job? —Preceding unsigned comment added by 193.15.240.60 (talk) 09:08, 20 December 2007 (UTC)
[edit] Link to Z-Wave
I have tried several times to change the Z-Wave link to the official Z-Wave.com website, but it seams like someone changes it back to z-wave.ru as soon as i have changed it. The official site is Z-Wave.com please leave the link as it is. —Preceding unsigned comment added by 69.95.44.86 (talk) 00:07, 5 May 2008 (UTC)
