Wireless telemetry and control in plants have become a necessity with the data acquisition requirement of modern plant control to lift performance and compliance. In-plant cabling costs often push the economic viability of peripheral plant data acquisition and control systems projects into the pending list of plant capex. The benefit of having the data and control is undeniable, but often too expensive to implement. Wireless control and automation provide a cost-effective solution and the technology is improving all the time.
Licence free wireless bands are extremely attractive for cable saving in the plant. Distances of up to 20 km are not uncommon, even with these low power transceivers.
