- Motivation for Indoor Propagation Models
Predicting the propagation characteristics between two antennas inside a building is important especially for the design of cordless telephones, wireless local area networks (WLAN), and in some cases, indoor cellular base stations.
- Required Database
Categorize buildings into different elements and specify their material parameters for accurate indoor propagation modeling.
- Modified Free Space Model (MF)
The modified-free-space model analyzes the building concerning distances between walls and penetration losses of the walls, but the individual positions of the walls and their material properties are not considered.
- Motley-Keenan Model (MK)
The modified-free-space model analyzes the distances of the building between walls and penetration losses of the walls.
- COST-Multi-Wall Model (MW)
The multi-wall model gives the path loss as the free space loss including losses introduced by the walls and floors in the direct path between transmitter and receiver.
- Standard Ray Tracing (SRT)
The standard ray-tracing model (SRT) performs a rigorous 3D ray-tracing prediction which results in very high accuracy but at the cost of a large computational effort.
- Shooting and Bouncing Rays (SBR)
The shooting and bouncing rays method (SBR) performs a rigorous 3D ray-tracing prediction which results in high accuracy but potentially at the cost of a large computational effort.
- Intelligent Ray Tracing (IRT)
Accelerate ray-optical models by combining the advantages of ray-optical and empirical models.
- Dominant Paths (DP)
