Indonesia has officially transitioned from analog to digital TV broadcasting, making the STB (Set Top Box) an essential device for households. For those who still use older TVs, an STB ensures that you can continue enjoying broadcast programs in better quality without having to buy a new television. What is an STB?A Set Top Box (STB) is a digital receiver that converts digital broadcast signals into images and sounds compatible with analog TVs. In short, it acts as a bridge between modern digital broadcasting and older television sets. Benefits of Using an STB How to Use an STB Why is STB Certification Important?In accordance with regulations established by the government, devices that use radio frequencies must be certified. As with STBs (Set Top Boxes), these devices typically use WLAN frequencies, commonly known as WIFI. STBs are subject to regulations established by the government, namely KEPMEN KOMDIGI No. 12 of 2025 concerning WLAN frequencies. The following are the WLAN regulations permitted in Indonesia No Radio Frequency RLAN 2,4 GHz/5 GHz for access type 1 RLAN 2,4 GHz/5 GHz for access type 2 or Backhaul 1 2400-2483,5 MHz ≤ 27 dBm EIRP (500 mW) ≤ 36 dBm EIRP (4 Watt) 2 5150-5250 MHz ≤ 23 dBm EIRP (200 mW) – 3 5250-5350 MHz ≤ 23 dBm EIRP (200 mW) – 4 5725-5825 MHz ≤ 23 dBm EIRP (200 mW) ≤ 36 dBm EIRP (4 Watt) As an electronic device used by the general public, STBs must be certified to ensure their quality, safety, and compatibility. Cerapproval, as a certification agency, plays a role in ensuring that STBs on the market comply with Indonesian regulatory standards. By choosing a certified STB, users are guaranteed a device that is safe, durable, and complies with technical standards.
