EMI

Electromagnetic interference (EMI) might be coupled from the source to the router through the following coupling mechanisms:

•Capacitive coupling

•Inductive coupling

•Radiative coupling

•Common impedance coupling

•Conductive coupling

To prevent EMI, take the following actions:

•Take measures against interference from the power grid.

•Do not use the router together with the grounding equipment or lightning-prevention equipment of power equipment, and keep the router far away from them.

•Keep the router far away from high-power radio launchers, radars, and equipment with high frequency or high current.

•Use electromagnetic shielding when necessary.
