Frequency Allocation & Assignment

last updated 22 May 2017

Singapore Allocation Chart

The radio frequency spectrum is divided into frequency bands allocated to various radiocommunication services such as aeronautical, land mobile, meteorological and satellite communication services. View Chart.


Radio Spectrum Master Plan

The Radio Spectrum Master Plan (updating in progress) serves to inform the industry and interested parties on the availability of spectrum in the coming years, technological trends in the use of spectrum and IMDA's policy direction with regard to spectrum allocation and re-allocation for public communication networks.


Singapore Spectrum Management Handbook

The Singapore Spectrum Management Handbook serves to provide information on Spectrum Management activities, assignment policies and the application procedures for the various radio-communication services including mobile, fixed, satellite, short-range devices and broadcasting services.


Short-term Commercial Use of E-band

IMDA will make available 71 – 76 GHz paired with 81 – 86 GHz of the E-band for commercial wireless applications such as fixed-wireless backhaul and inter-building fixed-wireless network. The spectrum will be available for short-term commercial use of up to 12 months until 31 December 2019. IMDA will monitor market and technology developments of the E-band, and take into consideration the World Radiocommunication Conference 2019 recommendations before allocating the spectrum in this band beyond 2020. Any request for annual renewal of the spectrum is subject to IMDA’s approval. Interested applicants may apply for short-term commercial use of this band where the applicable frequency fee is gazetted in the First Schedule of the Telecommunications (Radio-communication) Regulations under the shared use of radio frequency. The station or network deployment will be subject to licensing and the licence application guidelines for radio-communication station/network licences can be found online at IMDA website (Licence for The Operation of Radio-communication Station or Network).

Use of Frequencies for Unmanned Aircraft Systems (UAS)

Short-range devices (SRDs) generally refer to low-powered radio transmitters which have a localised area of operation. These include radio-communication equipment such as wireless microphones, cordless phones, remote control devices, etc. With the increasing adoption of Unmanned Aircraft Systems (UAS; more commonly known as Unmanned Aerial Vehicles or UAVs, and drones) for commercial and recreation uses, IMDA has published information to guide users on the safe operation of UAS in Singapore - please refer to the "Operation of UAS" for more information.
