Indonesia National Frequency Allocation Plan (2026)
The Indonesia National Frequency Allocation Plan (Tabel Alokasi Spektrum Frekuensi Radio Indonesia - TASFRI) is governed by the Ministry of Communication and Digital Regulation No. 8 of 2026. This plan updates and replaces Regulation No. 12 of 2022 to align with the International Telecommunication Union (ITU) Radio Regulations following the 2024 edition (WRC-23). It provides the legal framework for frequency assignments, band plans, and type approval requirements for radio equipment operating within the Republic of Indonesia.
Mobile Broadband and Cellular (IMT) Bands
Indonesia has identified several harmonized bands for International Mobile Telecommunications (IMT).
Manufacturers should note the following primary allocations:
700 MHz Band (694–806 MHz): Specifically allocated for IMT implementation (INS13), with 703–748 MHz for uplink and 758–803 MHz for downlink.
Extended L-Band (1427–1518 MHz): Identified for IMT and Broadband Wireless Access (BWA) (INS17A).
Standard IMT Bands: Primary allocations include 824–835/869–880 MHz (INS15), 880–915/925–960 MHz (INS16), 1710–1785/1805–1880 MHz (INS19), 1920–1980/2110–2170 MHz (INS21A), and 2300–2400 MHz (INS24).
2.6 GHz Band (2500–2690 MHz): Heavily utilized for cellular mobile networks (INS26).
C-Band (3300–3700 MHz): Allocated for IMT and BWA. The 3400–3700 MHz range is transitioning from Fixed Satellite Service (FSS) to IMT, with specific protection criteria for remaining satellite gateway stations (INS28).
Millimeter Wave (24.25–27.5 GHz): Identified for high-capacity 5G/IMT deployments (INS38).
Unlicensed and Short Range Devices (SRD)
Indonesia follows the ITU Region 3 framework for ISM and SRD applications, though specific local restrictions apply:
WiFi and RLAN: The 2.4 GHz (2400–2483.5 MHz) and 5 GHz (5150–5350 MHz and 5725–5825 MHz) bands operate under class license regimes (INS31).
6 GHz Band (6425–7125 MHz): Identified for Wireless Access Systems (WAS) and Radio Local Area Networks (RLAN), alongside IMT considerations (5.457E).
ISM Bands: Standard frequencies such as 13.56 MHz, 27 MHz, 40.68 MHz, 2400 MHz, 5.8 GHz, and 24 GHz are recognized for Industrial, Scientific, and Medical applications (5.150).
UWB and RFID: While general SRD rules apply, specific technical standards for power limits and bandwidth must comply with secondary status requirements to avoid interference with primary services like Radiolocation.
Satellite and Specialized Services
The 2026 plan introduces refined regulations for Earth Stations in Motion (ESIM):
ESIM Operations: Allowed in the 10.7–12.75 GHz (downlink) and 12.75–13.25 GHz (uplink) bands, as well as 17.7–20.2 GHz and 27.5–30 GHz, provided they communicate with GSO or non-GSO satellite systems and do not cause harmful interference (INS34AA, INS34D, INS34F).
High Altitude Platform Stations (HAPS): Identified for use as IMT base stations (HIBS) in several bands, including 698–960 MHz, 1710–1885 MHz, and 2500–2690 MHz (5.314A, 5.388A, 5.409A).
Regulatory Constraints and Coordination
Device manufacturers must adhere to "harmful interference" clauses. Secondary services (such as many SRDs) must operate on a non-interference, non-protection basis relative to primary services. Special priority is granted to Safety Services (Dinas Keselamatan), which includes international distress frequencies (INS36). Regulation No. 8 of 2026 explicitly revokes previous regulations regarding the 300 MHz band for Wireless Broadband and the 350–438 MHz planning, effectively consolidating the national frequency strategy into this single comprehensive document.
