Short Range Devices
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.
