For example, [[Ericsson]]'s telecommunications research and development subsidiary [[Telcordia Technologies]] publishes conformance standards for telecommunication equipment to pass the following tests:<ref name="EricssonElectro17">{{cite web |url=http://telecom-info.telcordia.com/site-cgi/ido/docs.cgi?ID=SEARCH&DOCUMENT=GR-1089& |title=Electromagnetic Compatibility and Electrical Safety - Generic Criteria for Network Telecommunications Equipment |publisher=Ericsson |date=December 2017 |accessdate=22 February 2018}}</ref>

; Radiated immunity : An [[antenna (electronics)|antenna]] is used to subject the device to [[electromagnetic waves]], covering a large frequency range (usually from 3080&nbsp;MHz to 2.96&nbsp;GHz).

; Radiated emissions : One or more antennas are used to measure the amplitude of the electromagnetic waves that a device emits. The amplitude must be under a set limit, with the limit depending on the device's classification.

; Conducted immunity : Low frequency signals (usually 10&nbsp;kHz to 80&nbsp;MHz) are injected onto the data and power lines of a device. This test is used to simulate the coupling of low frequency signals onto the power and data lines, such as from a local AM radio station.
