In-Building Engineering Capabilities
General Technical Features:
- Frequency range 100 MHz to 100 GHz
- The most accurate propagation predictions available using several selectable models, including:
- 2D and 3D ray-tracing models for outdoor microcell and indoor wireless LAN/PBX/cell-extender studies. Takes into account:
- Line-of-sight rays
- Wall transmission
- Corner diffraction
- Attenuation due to partial Fresnel zone obstruction.
- COST-231 Walfisch-Ikegami propagation model for simplified outdoor microcell studies.
- LBA propagation models explicitly account for the location of structures in the study environment and their electrical properties (conductivity, permittivity, and transmission loss).
- Time dispersion/multipath (RMS delay spread) studies and angle of arrival calculations can be performed.
- Multi-story indoor studies can calculate attenuation between floors and plot results in a 3D, multi-story projection.
- Considerations can be made for:
- Free-space propagation
- Specular reflection
- Diffraction
- Diffuse wall scattering
- Wall transmission
- Point study modes can project the ray trajectories to a particular point in the propagation environment. The effect on the ray amplitude and phase for each wall reflection and corner diffraction can be determined.
- Software permits time signature studies to show waveforms of received data pulses as a function of time to identify pulse shape distortions and echoes due to mutlipath and frequency-selective fading channel characteristics can be determined.
