Which term describes the decrease in signal strength of an RF even though there are no obstacles in the path between a transmitter and a receiver?
- transmit beamforming
- free space path loss
- link budget
- spatial multiplexing
Explanation: Whenever an RF signal is transmitted from an antenna, the signal amplitude decreases as it travels through free space. Even if there are no obstacles in the path between the transmitter and receiver, the signal strength will weaken. This is known as free space path loss.
