Accurate Propagation Models
This module offers 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
- EDX® Simplified Indoor Model (ESIM™)
for rapid, site-specific indoor signal strength calculations. 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.
Time Signature Displays
Time signature displays are available to show the waveform of the
received data pulse as a function of time. Pulse shape distortions and
echoes due to multipath are easily visible. Pseudo-animation mode
shows the dynamic nature of pulse distortions.time signature to
display frequency-selective fading channel characteristics.
Pseudo-animation mode shows the dynamic nature of the
frequency-selective spectrum response.
Features
Point Studies
The point study mode displays the ray trajectories to a particular
point in the propagation environment. This allows you to view the
effect on the ray amplitude and phase for each wall reflection and
corner diffraction.
RMS Delay Spread
You can calculate time dispersion/multipath studies (RMS delay
spread studies), angle of arrival, and angle of departure.
Multi-Story Studies
Calculate attenuation between multiple floors/ceilings.
Spectrum Signature Displays
Spectrum signature displays use the FFT of the time signature to
display frequency-selective fading channel characteristics.
Pseudo-animation mode shows the dynamic nature of the
frequency-selective spectrum response.
Study Environment
Propagation models explicitly account for the location of structures
within the study environment and their electrical properties
(conductivity, permittivity, and transmission loss).
System Parameters
Considerations are made for:
- Free-space propagation
- Specular reflection
- Diffraction
- Diffuse wall scattering
- Wall transmission
Additionally, the digital system
parameters control pulse shape and data rates. Parameters include
modulation type, data rate, and roll-off factor.
The Microcell / Indoor module can be used to enhance and/or increase
the accuracy of studies supported by the EDX family of products. These
types of studies include radio systems such as Wi-Fi and those used in
campus networks and urban areas.
