IMDA to make available new 5G spectrum bands to all mobile network operators

SINGAPORE – 26 JUL 2021

To support the next wave of 5G growth, the Infocomm Media Development Authority (IMDA) is seeking views from the public and industry on the potential use and allocation of the 2.1 GHz spectrum band for the 5G network in Singapore. The band is currently used for 3G services and will expire at the end of 2021. IMDA proposes to use the 2.1 GHz spectrum band to support the nationwide deployment of 5G Standalone¹(SA) networks in Singapore, while allowing flexibility for 3G services to continue.

As Singapore continues to forge ahead with our nationwide 5G network rollout², the availability of the 2.1 GHz spectrum will help provide opportunities for growth for all Mobile Network Operators (MNOs). The new spectrum can be used to complement existing 5G networks deployed, using the first tranche of 5G Call For Proposal (CFP) spectrum³, to enhance coverage and capacity, as well as the potential for deployment of an additional nationwide 5G SA network.

IMDA public consultation on policy issues & proposed regulatory design for 2.1 GHz

The 2.1 GHz spectrum band has good propagation characteristics, making it suitable for wide-area coverage for 5G⁴.

IMDA proposes to allocate the 2.1 GHz band for 5G networks in Singapore based on SA network specifications, in line with IMDA’s key 5G policy objectives to:

1. Maximise value of 5G for the economy and welfare for the consumers in Singapore;
2. Facilitate efficient allocation of scarce spectrum resources;
3. Bring about 5G networks that are secure and resilient; and
4. Support the 5G growth of Singapore’s telecommunications sector.

IMDA intends to allocate the new spectrum via auction, open to all existing MNOs if the MNOs wish to participate.  Through the market-based approach, bidders will get the flexibility to decide how much spectrum they require. All 2.1 GHz spectrum right holders must meet baseline regulatory requirements, consistent with the requirements on holders of the first tranche of 5G spectrum allocated through IMDA’s 5G CFP held in 2020. IMDA intends to hold the auction towards the end of 2021. As part of the auction design, IMDA intends to set aside some 2.1 GHz spectrum for the continued provision of 3G services in Singapore, for consumers who choose to continue to use these services.
