need some information about SCADA

Hi everyone,
I have a system and I need a solution for that.I'd really appreciate if you can help me.
I have a system which consist of 50 stations.These stations are PCs with Advantech GeniDAQ running on them.These stations gather the informatoion of a PLC and an IPC.
I want to put these stations in a wireless SCADA network and Monitor IPC and PLC information and supervisory control them.
How can I do that?What software and Hardware do I need?
Thanks alot.

I suggest your first step is to talk to Advantech, since you have some of their equipment already. They can supply almost everything you need, and nalthough their solution may not be optimum it can at least get you started on specifying a system.
