More Spectrum To Support 5G Growth In Singapore

SINGAPORE – 26 NOV 2021: The Infocomm Media Authority (IMDA) today announced the results of its 2.1 GHz spectrum auction to make available more spectrum to support the growth of 5G mobile services in Singapore. This spectrum is in addition to the first tranche of 3.5 GHz spectrum issued in June 2020 for the deployment of 5G nationwide networks. 

The 2.1 GHz spectrum rights auction is a key milestone in Singapore’s 5G journey to have a world-class, secure, and resilient infrastructure putting Singapore in a stronger position to grow our 5G innovation ecosystem; and positioning us for the next bound of growth in the digital economy by improving the 5G architecture.

The successful bidders were Singtel Mobile Singapore Pte Ltd (Singtel Mobile), a consortium comprising M1 Limited and StarHub Mobile Pte Ltd (M1-StarHub Consortium), and TPG Telecom Pte Ltd (TPG). 

Winning Bidders Amount of Spectrum Provisionally Awarded[1]
Singtel Mobile 5 lots of 5 MHz paired spectrum
M1-StarHub Consortium 5 lots of 5 MHz paired spectrum
TPG 2 lots of 5 MHz paired spectrum

Singtel Mobile and the M1-StarHub Consortium may use the new spectrum to enhance the coverage and capacity of their existing 5G Standalone (SA) networks deployed with the first tranche of spectrum issued by IMDA in 2020[2]. Both Singtel and M1-StarHub consortium are on track to establish two nationwide networks with full-fledged 5G SA capabilities[3] with at least 50% coverage by end-2022, and nationwide coverage by end-2025. 

TPG will be required to deploy a new 5G network in the same manner and time frame as Singtel Mobile and the M1-StarHub Consortium’s deployment conditions. TPG must roll out a 5G SA network with at least 50% coverage within two years, and nationwide 5G SA coverage within five years, from the commencement of its 2.1 GHz spectrum rights. TPG will also be required to ensure that its network will be secure and resilient. 

Winning bidders will have rights to the 2.1 GHz spectrum for deployment of 5G network and services from 1 January 2022.

All existing MNOs were also allocated mmWave spectrum to deploy localised high-capacity 5G hotspots. With this, M1, StarHub, Singtel, TPG Telecom and mobile virtual network operators are able to offer retail 5G services to end users.
