Communication Radio frequency plays a very important role in wireless communications, such as radio, television, and cellular phones.
Communication radio frequency is the range of electromagnetic wave frequencies used to transmit and receive information. These frequencies range from a few kilohertz to hundreds of gigahertz.
This range is subdivided into several frequency bands, each with different characteristics and propagation that support different types of communication. Find out more about the different types of communication radio frequency in this article.

The Types of Communication Radio Frequency
The following is a classification of communication radio frequency, sorted from lowest to highest:
1. ELF (Extremely Low Frequency): 3-30 Hz
This frequency is generally used for communication with submarines in the deep sea, as the waves are able to penetrate seawater very well.
2. SLF (Super Low Frequency): 30-300 Hz
SLF is also used in underwater communication, although it has limited bandwidth. However, it is still effective for transmitting simple signals in the marine environment.
3. ULF (Ultra Low Frequency): 300-3000 Hz
ULF is often used in specialized activities such as geophysical exploration and mining, as it is able to penetrate the ground and subsurface structures.
4. VLF (Very Low Frequency): 3-30 kHz
VLF is widely used for long-distance communication with submarines, navigation systems, and global time synchronization, due to its stability and wide range.
5. LF (Low Frequency): 30-300 kHz
These waves are typically used in maritime navigation and aviation. The advantage of LF lies in its long-range, especially at night when reflected back by the ionosphere.
6. MF (Medium Frequency): 300-3000 kHz
MF is the frequency range used for AM radio broadcasts. At night, its range can increase due to favorable atmospheric conditions.
7. HF (High Frequency): 3-30 MHz
HF is very effective for long-distance communications such as amateur radio, and is used in aviation and maritime navigation. This frequency can be reflected by the ionosphere so it can cover a very wide area.
8. VHF (Very High Frequency): 30-300 MHz
VHF is commonly used in FM radio broadcasting, television, emergency services, and public communications. It offers cleaner and more stable transmissions.
9. UHF (Ultra High Frequency): 300-3000 MHz
UHF supports services such as digital television, cell phones, GPS, and WiFi. This frequency is suitable for high-speed data transmission.
10. SHF (Super High Frequency): 3-30 GHz
Used primarily in radar systems and satellite communications. SHF is ideal for broadband connections due to its ability to transfer data very quickly.
11. EHF (Extremely High Frequency): 30-300 GHz
EHF is utilized in cutting-edge technologies such as 5G networks, military communications, and space exploration. Its high frequency enables extremely high data transfer speeds and resolution.
Those are the 11 different types of communication radio frequencies that you need to know in wireless communication. By deeply understanding the spectrum of communication radio frequency, we can better appreciate and utilize this technology to meet future communication needs.
What you need to know is that all forms of communication radio frequency in Indonesia must go through the Radio Frequency Test for Information and Communication Technology (ICT).
This test is to ensure the proper and safe use of radio wave frequencies so that they are eligible for circulation in Indonesia.
If you pass the test, your products related to communication radio frequency will receive a DJID (Direktorat Jendral Infrastruktur Digital) certificate following regulations from the Ministry of Communication and Digital (KOMDIGI).
For companies wanting to sell products related to communication radio frequency in Indonesia, Type Approval Certification Services for ICT Products are available to assist with this process. This service includes preparing technical and legal documents, conducting required testing, ensuring compliance with regulations, helping companies streamline the certification process, and giving consumers confidence in certified products.
