In general, the RED covers all products and equipment that intentionally transmit or receive radio waves for communications or radio determination in the frequency range from almost DC to 3000 GHz. This is independent of the product’s primary function as long as it includes, for example, a cellular communications standard such as WCDMA and LTE, a non-cellular standard such as WLAN, Bluetooth and RFID, a broadcasting standard such as AM/FM, DAB, DRM and DVB-T/T2 or radar or satellite navigation for radio determination. Such radio equipment needs to achieve a minimum level of performance in terms of sensitivity and selectivity, which must be demonstrated by appropriate measurements.
