1.1.1. General Q&A on EMI and RFI

The following are general questions and answers regarding steps to avoid nearly all of the effects of EMI and RFI with this device. Please use them as reference.

011 / 202
Section 011

Where do radio waves come from?

Radio waves are emitted by unidirectional or bidirectional radio devices. Such devices include transceivers, mobile phones, wireless computer links, microwave generators, and radio call transmitters. Radio waves are a form of electromagnetic energy, and the strength of the energy increases at closer distances to the transmitting antenna. This electromagnetic field can cause problems for users of electric equipment.

012 / 202
Section 012

What kind of movements should I expect if a mobility device is affected by EMI or RFI?

EMI and RFI undergo extremely large dynamic changes and may affect a device depending on conditions such as the following.

  • Radio wave frequency and strength
  • Structure of the power supply equipment
  • Inclination of the device (whether the ground is flat or a slanted)
  • Whether the device is turned on and whether it is moving

If this device is affected, there is a possibility of abnormal movement. It may begin moving uncontrollably or stop suddenly. Strong EMI or RFI can damage the control system.
