7. APPLICATIONS
The free space propagation model, also known as the free space path loss model, describes the
attenuation of electromagnetic waves as they propagate through a free space environment
without any obstacles or interference.
1.Wireless Communication Planning: Free space path loss is used in the design and planning
of wireless communication systems, such as cellular networks, Wi-Fi networks, and satellite
communication systems. It helps estimate signal strength and coverage areas.
2.Satellite Communication: When designing satellite links, engineers use the free space
propagation model to calculate the expected signal strength between the satellite and the ground
station. This is crucial for ensuring reliable communication.
3.Radar Systems: In radar systems, particularly for long-range detection, understanding free
space propagation is essential. It helps estimate the radar's maximum range and detectable
targets.
4.Wireless Sensor Networks: In applications like environmental monitoring or industrial
automation, where sensors communicate wirelessly, understanding free space path loss assists in
determining the optimal placement of sensors and base stations.
