Italics_ Scope and basic requirements of the directive - Radio equipment Radio equipment is defined as a product and related components capable of communicating by transmitting/or receiving radio waves using the allocated ground/space radio spectrum, where radio waves refers to the frequency range for which time, electromagnetic waves that can propagate in the air without artificial guidance. According to this definition, radio equipment has three basic characteristics. It can communicate. Communication is carried out by transmitting and/or receiving radio waves. The frequency range of radio waves is to. According to radio The propagation characteristics and uses of waves can be divided into several bands or frequency bands, such as very low frequency, low frequency, medium frequency, high frequency, very high frequency, and microwave. Due to various countries, various industries and even various enterprises, they have different requirements on radio waves and their different frequency bands. There are differences in the definitions, so the frequency used by the equipment should be strictly followed to determine whether it falls within the scope of the directive. Typical radio equipment that falls within the scope of the directive. Radio broadcasting equipment, including audio and video radio broadcasts, such as broadcast transmitters and other digital cordless telecommunications equipment, including transmitting and receiving Equipment Digital Radio Relay Systems Fixed Wireless Access Global Maritime Distress and Safety System Systems High-Performance Wireless LAN Systems including transmitting and receiving equipment Specialized mobile radio systems such as walkie-talkies and other terrestrial, aeronautical and maritime satellite communications systems Short-range radio equipment, including Bluetooth Equipment, remote control equipment, etc., such as remote control door keys, wireless alarms, remote control toys, wireless mice and keyboards, etc. Ground trunking wireless systems and other equipment 2. Telecommunications terminal equipment In the directive, telecommunications terminal equipment is defined as a product or related product that can communicate Components, used to connect directly or indirectly to the interface of the public telecommunications network in any way. That is to say, there are three characteristics that need to be paid attention to. It is capable of communicating directly or indirectly to the interface of the public telecommunications network. The public telecommunications network includes ordinary public analog. Or digital telephone network, network, etc. Typical telecommunications terminal equipment includes terminal equipment, including basic rate, base rate, and broadband terminal equipment, including analog single line, analog multiline, equipment connected to interfaces or virtual private networks, leased line terminals Equipment and other terminal equipment connected to the fixed network
