802.11 wireless devices?
« on: January 09, 2007, 12:43:50 PM »

I'm wondering how hard (and expensive) would it be to totally get rid of PLC and use wireless (preferably standard 802.11) to connect (two-way) to all devices. Is there any product like that (e.g. wireless ethernet TCP/IP cheap controllers)?

Many products. Google "Z-Wave" for a start,  but it is not 802.11

Good Evening,

The 802.11 is the wireless local area network developed by the IEEE LAN/MAN Standards Committee (IEEE 802) in the 5GHz public spectrum and was not designed for nor intended for remote control.  Using it as a valid network with TCP/IP would work but that is a lot of overhead.  The chips in volume would, the micro and other items would push $35 in total just for the chips.  Please note I have not priced these parts but do see them in trade publications.

There are many other frequencies allocated for remote control and would be much more cost effective to implement.  Good Idea though.

Have fun

IMHO, you need to drop the "cheap" out of your requirements.    ;D

Good Evening,

Cheep is a subjective term. Consequehtly it does not have an exact meaning.  I would suggest you subscribe to "Circuit Cellar".  The last issue has some interesting information on data acquisition.  There are many adds for network appliances that could do what you want, just add software.

Good Luck
