OTS ; Off-The-Shelf
Stuff already designed and ready to buy and use..
Kinda like "Pr�t-�-porter" ;)

Thanks! Can you tell me more about "OTS"? I can't seem to get on the right
track with either google.com or deja.com...

A 802.11x transceiver will be relatively power hungry. If you use a
different wireless solution and have a receiver box that does the IP
networking for you, it will be a lot easier to get the power requirement
way down. Wireless security sensors run for years on battery - sometimes
even longer than the shelf life of the battery, and range is much better
than 802.11x.
You could use an OTS transmitter/receiver (check Honeywell, GE, Visonic,
or even X-10) and hook it in to whatever networking solution you want...
If there is more than one wireless beam per site, I bet it would
also make it more cost efficient this way.

I'm looking for the smallest embedded device I can find that can do:
1. Infrared sensor
2. Wireless connection (can connect to an G router, for example, I'll have
to check the
distance that might cover, otherwise maybe N will have to be used)
3. DHCP
4. Low power consumption
5. User solar power to save battery life?
At least have a couple out of 5, and I can try to work on the others.
I'll need the infrared sensor (beam break detector) to trigger either a
single UDP packet or TCP
(handshake) and all.
A tall order? ;-)
How can I get started? Any ideas?
I need perhaps wireless connectivity up to like 100 feet to start, and might
also need a strong enough signal to go through a few solid walls...
Bluetooth is out...
