How to improve industrial data communication

Industrial data communication is characterized by its operating environment. The need to overcome electromagnetic interference (EMI), long distances, and both physical and economic barriers to installing transmission media sets industrial communications requirements apart from typical business office requirements. All too often, however, conventional data communications equipment is called upon to function in industrial environments with unsatisfactory results. One method to correct this problem is the use of digital data logic highs and lows to modulate a carrier signal. Properly selected and configured carrier signals can overcome most of the EMI and distance problems that affect industrial communication. Modulated carriers can be transmitted many miles on wires and much more noise immune and versatile data communication technique.
