Hi I am a college student. I am doing a project on wireless networks. I would like to connect all Zigbee networks in each floor into a single network controlled by a remote controller in a building. Thanks for your help.

You use a gateway. It keeps networks separated.

I think I misread your question, sorry I am justwating for an answer tomine passing the time.

To connect two networks you use a dual input router such as those that takes both cable and dsl as inputs.
