Slow and steady
In industrial applications, reliability is more important than speed. The data being transmitted is usually simple sensor or control data, which requires very minimal bandwidth.
Reliability in industrial applications is, however, of utmost importance. When you’re communicating with sensors and controls to devices that are often very large and expensive—and often dangerous—you want to be sure the data goes through.
Plus, industrial environments are often difficult for wireless transmission because of long distances, and interference from large motors and reflective metal surfaces. For these reasons, wireless devices built for industrial use tend to be very slow but quite reliable.
Tough as nails
Industrial environments can be tough, exposing electronics to vibration, dust, moisture and extreme temperatures. For this reason, industrial wireless devices are usually housed in far more robust enclosures than devices intended for office environments. Standard features to look for are heavy-duty steel cases, water resistance, dust resistance and extended temperature ranges.
