FreeSpace

Free space propagation model

Description

Model the behavior of electromagnetic radiation from a point of transmission as it travels through free space by using a FreeSpace object. Free space propagation models have no enforced frequency range, assume line-of-sight (LOS) conditions, and disregard terrain, the curvature of the Earth, and other obstacles.

FreeSpace objects have no properties.

Creation

Create a FreeSpace object by using the propagationModel function.

Object Functions

pathloss	Path loss of radio wave propagation
range	Range of radio wave propagation
add	Add propagation models

Examples

Model Coverage in Free Space

Display the coverage area for a transmitter in free space.

pm = propagationModel("freespace");
tx = txsite("Name","Apple Hill","Latitude",42.3001,"Longitude",-71.3604);
coverage(tx,pm)
