IMDA allocates the right to use spectrum in Singapore through different methods, including auctions and assignments. The method by which different frequency bands are allocated for use is determined by the demand for the band, the potential uses of the band, and other properties of the band. View the auctions and assignments that IMDA (and then IDA) have undertaken for spectrum.

Short-Term Assignment of Unassigned Spectrum in the 2.3 GHz and 2.5 GHz TDD Spectrum Bands
23 January 2015
IDA issued an Information Paper on 23 January 2015 to clarify IDA's framework for short-term assignment of Unassigned Spectrum in the 2.3 GHz and 2.5 GHz TDD Spectrum Bands (149.56KB).
Assignment of Frequencies on Non-Interference and Non-Protection Basis
4 July 2019
IMDA has further revised the Information Paper on IMDA’s Framework for Assignment of Frequencies on Non-Interference and Non-Protection Basis (“Constrained Band Framework”) (613.73KB). This supersedes the Information Paper issued on 17 March 2016.
17 March 2016
IDA has revised the Information Paper on IDA’s Framework for Assignment of Frequencies on Non-Interference and Non-Protection Basis (“Constrained Band Framework” (185.08KB)). This supersedes the Information Paper issued on 8 March 2010. IDA will make available frequencies from the 1800 MHz centre gap (i.e., 1790 – 1800 MHz) for commercial use to provide telecommunication services, in accordance with the Constrained Band Framework. Any assignment under the Constrained Band Framework will be on a first-come-first-served basis, subject to the submission of a duly completed proposal by the interested party to IDA at IDA_TLSINFO@imda.gov.sg with the email header “Assignment of Frequencies on Non-Interference and Non-Protection Basis”. IDA will start accepting proposals for consideration from 18 April 2016 onwards.
1 July 2015
Following the 4G Auction in 2013, IDA has assigned 2500 to 2560 MHz paired with 2620 to 2680 MHz via the 2.5 GHz Spectrum Right (2013), which takes effect from 1 July 2015. Hence, these spectrum bands are no longer available for assignment under non-interference and unprotected conditions.
8 March 2010
IDA issued an Information Paper on 8 March 2010 to clarify IDA's framework for assignment of frequencies under non-interference and unprotected conditions. IDA has received applications for the use of the "constrained" radio frequencies:
from 2500 to 2512 MHz, and 2620 to 2632 MHz;
from 2532 to 2540 MHz, and 2652 to 2660 MHz;
from 2512 to 2516 MHz, 2528 to 2532 MHz, 2632 to 2636 MHz, and 2648 to 2652 MHz; and
from 2600 to 2620 MHz;
for the provision of wireless broadband service in Singapore.
