· Telecom/Radio Frequency (RF) Testing


Telecom is a wire-based communication method with advantage of branching that ensures a stable and high-quality transmission line compared to wireless communication. The testing is required to verifry electrical safety and electromagnetic waves. Therefore, we, SK Tech, support with all related national/global testing technical standards for the the flourishment of your business.


Radio frequency (RF) testing is needed for radio and telecommunications equipment to verify that they are using effective radio spectrum by not interfering with those using frequency band as well.

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


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