Why are lower frequency signals advantageous in some communications?

Lower frequency signals are advantageous in communications primarily due to their longer range capabilities. This attribute stems from the fact that lower frequency signals can propagate over greater distances with less signal loss compared to higher frequency signals. They are less prone to attenuation and can travel through obstacles such as buildings and natural terrain more effectively, making them ideal for applications that require transmitting information over long distances or in challenging environments.

In addition to range, lower frequency signals often exhibit better penetration through various materials, such as walls and foliage, whereas higher frequency signals tend to get absorbed or reflected more easily, limiting their effective range. Thus, for communication systems that aim to cover large areas or maintain connections in diverse environments, the use of lower frequency signals becomes a strategic advantage.
