“Please turn off all personal electronic devices, including laptops and cell phones. Thank you!”
Many of us who have boarded a commercial flight are familiar with this quirk of air travel. If you own a smartphone, it likely features a toggle called “Airplane Mode” somewhere in your settings. Why? And what does it have to do with manufacturing?
The answer is Electromagnetic Interference, or EMI.
Historically, cell phones are considered a culprit of EMI, which can impact the performance of navigation instruments in a plane. In manufacturing, EMI plays an even bigger role in producing “dirty power” that can pollute an electrical system.
This could be a major factor behind your factory’s unplanned downtime when equipment falters or the entire system shuts down.
