Understanding Line of Sight (LOS) in Wireless Communication

LOS stands for "Line of Sight". In the context of wireless communication, it refers to a direct path between two points without any obstacles or interference. In other words, it means that there is an unobstructed view between the transmitter and receiver.

In wireless networks, LOS is important because it can affect the range and quality of the signal. If there is no LOS, the signal may be weakened or blocked by physical barriers such as buildings, hills, or trees. This can result in poor coverage and connectivity issues.

LOS is typically measured in terms of the number of obstacles between the transmitter and receiver, or the distance between them. The more obstacles or distance between them, the weaker the signal will be. To ensure good LOS, wireless networks are often designed to minimize physical obstructions and maximize the distance between the transmitter and receiver.
