What is radio frequency testing?

Radio frequency testing is needed for radio and telecommunications equipment to test they are using the radio spectrum effectively by not interfering with other users of the radio frequency spectrum.

A radio frequency test covers technology such as Wi-Fi, Zigbee, PMR radio, RFID, NFC, GPS, cellular technologies and more. Other tests are also usually required to verify that a device meets local regulations for electromagnetic compatibility (EMC), electrical safety and RF exposure.

Why is radio frequency testing important?

Radio frequency compliance is a mandatory requirement in most international markets including the EU, the US, Canada, Australia and Japan. If you manufacture wireless devices or incorporate wireless devices into your product, you must comply with the regulations of your intended markets, otherwise your products cannot be legally sold. Radio frequency testing can also reveal problems early helping brands avoid costly rework and gain access to global markets fast.
