Short Range Devices(SRD)
Short Range Devices (SRD) are radio devices that offer a low risk of interference with other radio services, usually because their transmitted power, and hence their range, is low. The definition 'Short Range Device' may be applied to many different types of wireless equipment, including various forms of:
Access control (including door and gate openers) Alarms and movement detectors Closed-circuit television (CCTV) Cordless audio devices, including wireless microphones Industrial control Local Area Networks Medical implants Metering devices Remote control Radio frequency identification (RFID) Road Transport Telematics Telemetry.Short range devices often benefit from a relaxed regulatory regime compared with other radio communications equipment. As a general principle, a user is licence free to operate such equipment, some specific cases may require an individual licence. However, like all radio equipment, short-range devices have to meet the Radio Equipment Directive (RED) to be placed on the market within the European Community. The operation of the equipment is subject to the frequency management regulations of the relevant member state.
短程设备(SRD)是一种无线电设备,它提供与其他无线电服务干扰的低风险,通常是因为它们的发射功率和射程都很低。“短程设备”的定义可适用于多种不同类型的无线设备,包括各种形式的:
门禁(含开门器) 警报和移动探测器 闭路电视(CCTV) 无绳音频设备,包括无线话筒 工业控制 局域网 医用植入物 计量装置 远程控制 射频识别(RFID) 道路运输远程信息处理 遥测,远距离测量与其他无线电通信设备相比,短程设备通常受益于宽松的监管制度。作为一般原则,用户无需许可证即可操作此类设备,某些特定情况下可能需要单独的许可证。
然而,与所有无线电设备一样,短程设备必须符合欧洲共同体市场上的无线电设备指令(RED)。设备的操作应遵守相关成员国的频率管理规定。
