| History | |||||||
| Although Indonesia did not at WRC-07 sign any of the IMT opt-in footnotes in the 3 400 – 3 600 MHz band Indonesia had licensed FWA in the extended C-band. Pasifik Satelit Nusantara (PSN) is one of the satellite operators that experienced interference into FSS C-band operation. Since the extended C-band is widely used for FSS in Indonesia this service is especially prone to interference.
On January 22, 2009 the Indonesian government issued two ministry decrees and three regulations releasing spectrum at 2.3 GHz and 3.3 GHz for BWA for all of Indonesia. Indonesia uses the 2.3 GHz band for the mobile WiMAX 802.16.e Standard and the 3.3 GHz band for the fixed WiMAX 802.16d Standard. The most common frequency bands for WiMAX equipment are 2.3 GHz, 2.5 GHz and 3.5 GHz although some companies have now developed WiMAX equipment using the 802.16d Standard for the 3.3 GHz band. Indonesia is in footnote No. 5.429 which also allocates the band 3 300 – 3 400 MHz to the fixed and mobile services on a primary basis and as such can be used for BWA. The government has issued a decree ordering the migration of WiMAX services out of the 3.5 GHz band and into the 3.3 GHz band. Even at 3.3 GHz, out-of-band interference into FSS C-band (especially extended C-band) is still possible. However, operators have found that by using new equipment the out-of-band interference into FSS could be controlled. |

| Present Situation | |||||||
| Indonesia does not license FWA in the C-band (both extended and standard). Due to extensive use of the C-band (both extended and standard) in Indonesia, Indonesia is of the opinion that the band 3.4 – 4.2 GHz is not suitable for IMT under the WRC-15 agenda item 1.1. National position on 3.4 – 4.2 GHz band under WRC-15 agenda item 1.1:

| Interference into FSS C-band Applications | |||||||
| There had been reports of interference into the FSS C-band VSAT and TVRO from earlier FWA operation in the 3.5 GHz band. However, with FWA now operating in the 3.3 GHz band and by using new FSS equipment operators have found that the out-of-band interference into FSS could be controlled. | |||||||
