Among the most prevalent radio systems in Ireland are Short Range Devices (SRDs). These are uni-directional (one-way) and bi-directional (two-way) low power radio transmitters that serve a multitude of purposes e.g. car door openers, sensors, tagging devices, alarms, wireless microphones and wireless local area networks (WLANs). Additionally, SRDs are used for specialized applications such as Road Traffic and Transport Telematics (RTTT) for the management of roads and traffic e.g. automatic road toll collection and traffic information.

SRDs operate in many frequency ranges in the radio spectrum, from kilohertz, through megahertz to gigahertz frequencies. Due to their low power and localised usage, SRDs are generally regarded as having a low capability of causing interference.

Short range devices that operate in accordance with ComReg document 02/71R2 are exempt from licensing in Ireland. They typically operate in frequency bands shared with other radio services and are permitted to operate on a non interference, non-protected basis. Effectively, this means that they should not cause interference to other legitimate spectrum users, nor can they claim protection from interference from other spectrum users.

ComReg will facilitate new licence exempt services by making spectrum available wherever possible for such applications, subject to demand and technical feasibility.

ComReg will continue to exempt services from licensing where this is appropriate in the Irish context.

ComReg will monitor and contribute to international developments in licence-exempt applications and technologies and where appropriate, ensure these can be accommodated in Ireland.
