Wireless systems are coming to your plant. Fact is, this is old news. We’ve talked about it for a while now.
You probably already have wireless devices in your plant, because wireless isn’t limited to sensor networks. You already have analog wireless—handi-talkies, maybe some point-to-point analog wireless sensor signals, 802.11 a/b/g/n WiFi, cellphones and maybe even some Bluetooth M2M (machine to machine) connections. You may even have one of the newer digital mesh-based wireless sensor networks.
