What you need to know about electromagnetic interference

Electromagnetic interference is one of the many types of disturbances that can affect your network. Also known as radio frequency disturbances or electrical line noise, these interferences can affect our everyday lives, but it's important to be prepared so it does not disrupt business. 

EMI, explained
EMI is the interference created by an electronic device, channel or transmission. EMI comes in two types: conducted, in which the devices are touching one another, and radiated, which is transferred by electrical currents. 

Sources of EMI
There are many potential causes of electrical interference, and our reliance on electronic devices has only made them more common. These sources can include: 

• Cell phones: There is a reason the pilot asks you to turn off your devices when an airplane takes off. That's because the EMI from mobile devices can affect navigation signals. 
• Aircraft: On the flip side, low-flying aircrafts can generate EMI that can disrupt video or audio signals. 
• Lightning, electrical storms or solar flares: In addition to man-made devices, natural events like these can also cause EMI. 
• Fluorescent lighting: When located near cables, fluorescent lighting can create erroneous data due to EMI. 

Effects of EMI
This interference can have a number of effects on electrical equipment. Without taking proper measures, EMI can lead to costly downtime for businesses. 

• Data corruption or loss: Devices and the data they capture can be negatively affected by EMI signals. 
• Equipment lockup: EMI can cause electrical equipment to lock up or shut down. 
• Jamming radio networks: EMI can be put to use in modern warfare. Combatants use the interference to cut off enemy communications. 

How can you protect your business from EMI-caused problems? 
A UPS system can help keep your network running. Uninterruptible power supply provides emergency power when equipment fails. While a deviation in voltage can cause a computer's systems to fail, UPS devices detect these deviations and immediately route their battery power to the computer, maintaining a steady power flow and keeping systems working.
