The Ministry of Communication and Information Technology (KOMINFO) of Indonesia has completed the entire process of refarming the 800 MHz and 900 MHz radio frequency bands as of April 2, 2019. Both of these radio frequency bands are used for cellular telecommunications services, ranging from 2G, 3G, to 4G technology.

This process, which started on January 23, 2019, was originally scheduled for completion on March 21, 2019 and since has been delayed two weeks because the number of base stations was twice the original estimate.

Refarming optimizes the radio frequency bands for cellular services in Indonesia by making the frequency bands of each cellular telecommunications operator contiguous.

The reallocation was split into three stages. With contiguous conditions, the utilization of radio frequency bands for cellular is optimized.

The efficiency of the utilization of radio frequency spectrum resources encourages telecommunication operators to increase 4G network penetration, which results in a more evenly distributed 4G network throughout Indonesia.
