The Infocomm Media Development Authority (IMDA) of Singapore has updated the technical document pertaining to Short-Range Devices.
SRDs may be fixed, mobile or portable stations that come with a radio frequency output connector and dedicated antenna or an integral antenna. Applications include alarms, identification systems, radio detection, vehicle radar systems, wireless local area networks, remote controls, telecommand, telemetry and on-site paging systems. These devices may employ different types of modulation and may have speech applications.
Some of the main changes to the Short-Range Devices pertain to wireless, RFID, access points, and radars. Along with that, the main changes to the August 2021 document are changing the format and wording of the document.
Another update as well is that IMDA added a Sub-Section for Equipment Safety Testing (4.2.2) as well as a Conformity Assessment Checklist for SRDs (Annex A).
