I have already talked about using this module as key for a home automation central. I am going to look into a few extensions (or additional module).
A normal wireless have a range on ca 100m, but dealing with home automation you could use 1Km range – solutions for that exist.
Another change is the capability to use this as a wireless router creating a privat, wireless sone that can be extended.
The alternative is 1km long twisted wires for RS485 or modem’s, but a wireless solution is so much easier. I will be back on these extensions later.
