![]() ![]() This means that the farther away the receiver is from the satellite, the lower the received signal strength will be, and the lower the SNR. As the signal travels through space, it becomes weaker due to a phenomenon known as free-space path loss. However, increasing the signal power is not always the most efficient solution, as it can also lead to increased interference with other satellite systems and potential regulatory issues.Īnother important factor is the distance between the satellite and the receiver. The most obvious is the power of the transmitted signal, which can be increased by using a larger satellite dish or a more powerful transmitter. There are several factors that can affect the SNR in a satellite communication system. In general, a higher SNR is always desirable, as it ensures that the transmitted information can be accurately received and decoded by the receiver. Conversely, a low SNR means that the signal is barely distinguishable from the noise, leading to poor communication quality and potential data loss. The SNR is typically expressed in decibels (dB), a logarithmic unit that allows for easy comparison of signal and noise levels.Ī high SNR indicates that the desired signal is much stronger than the background noise, resulting in a clear and reliable communication link. In satellite communications, the desired signal is the information-carrying signal transmitted by the satellite, while the noise refers to any unwanted signals or interference that may be present in the system. SNR is a measure of the strength of a desired signal compared to the level of background noise present in a communication system. One such term is the Signal-to-Noise Ratio (SNR), a critical factor in determining the quality and reliability of satellite communications. As the demand for satellite services continues to grow, it is important to understand the key concepts and terminology that underpin this technology. Satellite communication has become an essential part of our daily lives, enabling us to access information, entertainment, and stay connected with people around the world.
