What are Banda Ku, Banda Ka and Banda C?

Anyone who follows the news related to technology must have realized that in recent months a lot has been said about network news. We are in the process of studying and bidding for the implementation of 5G, which should occur by 2022. However, when you check the news you will come across some technical terms that you are not yet familiar with. This is the case for transmission models, which are classified by operating frequencies, or bands. The best known are Ka, Ku and C. Communication bands have different characteristics.

See in this article what are Band Ku, Band Ka and Band C, what are the differences and definitions of these transmission models so important for telecommunications.

What is Band?

Equipment used for wireless communication uses a frequency or set of frequencies called a band. They are normally used for the transmission of information and data. Many devices have the function of wireless communication and satellites are no different. The satellite uses a combination of frequencies in order to transmit the information. The satellite internet uses the bands – Band Ku, Band Ka, and Band C.

What is Band Ka?

The ka-band frequencies are the one with the highest frequency and the largest band spectrum to operate, in the range of 27 and 40 GHz. It has been avoided for a long time, as it is more susceptible to signal degradation, rain-fade phenomenon, and absorption of radio signals through ice, snow or the atmosphere itself. Companies have run after technology to reverse this situation, already offers broadband internet on the Band Ka frequency, feeding the most distant regions with its connection.

It is the solution to the lower frequency congestion problems. The increase in the Ka band’s operability is due to the high demand for internet-based processes. It is not simply an escape zone from Band Ku. Band Ka has a new type of transmission architecture with bandwidth management, satellite models that offer higher quality, better performance and quick access.

What is Band Ku?

Ku band is one of the frequency bands that are used for satellite internet. Its communication model is usually used in the movement between satellite – antenna and vice versa. The physical characteristics found in your antennas are simpler than those of other frequencies. They are small, with more fragile material, and their cost is very low.

The quality of the material used interferes with its performance, constantly undergoing climatic interference. The frequency range used commercially is between 10.7 GHz and 18 GHz and is also used by TV stations, other services such as radars and the police.

What is Band C?

Band C is a frequency range that satellites use to carry out communication using the frequency spectrum between 3.7 GHz to 6.425 GHz and works for transmitting data both analogue and digital. It is recognized for its great signal stability: allowing information to continue traveling even under adverse climatic conditions, weather closed with heavy clouds, heavy rain, excessive pollution and even forest evaporation. The operational cost to use this band is lower. The investment can be recovered over time, but the starting capital must be robust.
