The Info-communications Media Development Authority (IMDA) has released the updated technical specification, IMDA TS CMT Issue 1 Rev 3 (Dec 2024), for Cellular Mobile Terminals (CMTs) in Singapore.
This update consolidates requirements for various cellular technologies including 5G, and introduces new requirements with significant implications for manufacturers. Key areas of change include RF EMF safety, which now mandates the use of IEC/EN 62209-1528:2020 standard by October 1, 2025, replacing older standards (IEC/EN 62209-1 and IEC/EN 62209-2).
Additionally, the updated specification includes mandatory requirements for VoLTE (Voice-over-LTE) functionality for devices designed for voice calling. These devices must be compatible with all mobile network operators in Singapore, with VoLTE functionality enabled by default, and must also support emergency calls via VoLTE. The document specifies the technical requirements for various aspects of CMTs, including operating frequencies, radio interface, and electromagnetic compatibility (EMC).
Manufacturers and suppliers of CMTs for the Singapore market must ensure their products comply with these updated standards to maintain market access.
