As we have mentioned in other posts, Band frequencies are made to shorten distances, as far as communications are concerned. In this way, we can infer that satellites are arranged throughout the space, by preserving the way of transmitting messages of all types.
Let’s go to the elementary: one principle says that wavelengths have different properties. To cite an example and understand it better, the wavelengths that have long waves have the property to travel great distances and go through obstacles that find in their way, such as buildings and mountains; but it is also worth noting that the higher the frequency, and in turn, the shorter the wavelength, it will be easier to stop the normal traffic of the waves.
We must talk about a situation that cannot be overlooked, and that is when frequencies are high enough, even above tens of gigahertz, the waves can be stopped by objects that for us can be as simple and small as tree leaves or raindrops, thus causing a recognized phenomenon called “rain fade”, which is overcome by applying more power.
An infallible satellite solution
Many times, we have talked about the advantages that high frequencies offer, such as the Ka Band and Ku Band. We already know their features and ways of use, also, that these allow transmitters to send more information per second. The problem with these high frequencies is that they grant the initial possibility of carrying more information, but they need more power to avoid blockages, also larger antennas and this ultimately means that more equipment must be acquired.
The solution to this dilemma is provided by the L-Band, as it has important characteristics in satellite communication, such as providing more stable global operations, even when the weather conditions are adverse in complicated areas, providing a global network coverage, which It has no interruptions, and that additionally allows broadband communications to mobile users established anywhere around the world.
What are the applications of the L-Band?
This frequency range is one of the most used in a wide variety of satellites worldwide. The L-band antennas give the portable advantage of being small and lightweight, so they are especially used for tactical and mobile operation. Other of the pillars for its use, are given in various systems, including search and rescue operations, such as the case of SARSAT/COSPAS, which we remind are on board some meteorological satellites used by many Americans, as Russians, since this band is ideal for the downlinks present in high resolution satellites.
Frequency range in which Band L operates
To round off the faculties that adorn the L Band satellite frequency, we must say that the L band operates in a range of frequencies ranging from 1,530 to 2.7 Ghz, being the one with the lowest frequency amongst satellite bands used in the market. For its benefit, it has a longer wavelength and, therefore, it is not affected by external factors such as rain, which it does occur with much larger parabolic antenna systems, normally used by the Ku and Ka frequency bands.
