Path loss model

A path loss model describes how the strength of a wireless signal decreases as it travels through space from a transmitter to a receiver. Factors such as distance, obstacles, and the environment affect this loss. Essentially, it predicts how much weaker a signal becomes over a certain distance, helping in designing reliable communication networks. For example, signals tend to weaken with distance and when passing through walls or buildings, making it important to account for these effects to ensure good connectivity and coverage.
