INTRODUCTION
Mobile-CDS is a 3D deterministic propagation tool with unlimited potential in areas such as; RF
characterization of specific regions, wireless protocol evaluation and military applications. Its internal engine
is based on ray-tracing technology and the code is fully parallelized.
From the comfort of his or her office, using Mobile-CDS the wireless system engineer is able to change
several simulation parameters (i.e., the TX and RX antenna height and gain patterns, the carrier frequency,
material properties, propagation environment, etc.) and determine their impact on the received signal.
Product design cycle time is greatly reduced and money is saved by avoiding expensive and time consuming
field data collection campaigns. Field data is only gathered at the end of the design cycle for verification
purposes.
During the next hour detailed characteristics of the tool and some of its capabilities will be presented. We
hope that during this time you all enjoy the presentation and if there are questions, feel free to ask.

q Simple to use GUI supporting the following functionalities:
Ø Protocol generation.
Ø 3D databases (importing, exporting, cloning, cropping, etc.).
Ø Propagation analysis (received power, delay spread, co-channel, etc.).
Ø Computational engine settings.
Ø Materialmedia library.
Ø Graphics.
q Algorithms supporting LOS (line of site) reflection and transmissions and diffraction propagating modes are build in the original code.
Geometrical optics is used to approximate the reflected and transmitted fields. UTD is used to estimate the over the roof and side walls
diffracted fields.
q In addition to the original facet format, the tool is able to handle other 3D databases formats such as .kml. Both, flat and undulated terrains
can be incorporated into the analysis as well as any objects like building, trees and vehicles.
q No limitation on the type of environment used in the simulation; urban, suburban or rural.
q Able to incorporate in the analysis complex antenna patterns represented by their Eq and Efcomponents. The antenna patterns can be
generatedusing an electromagneticsolver (XFDTD), anechoic chamber measurements or data provided by a vendor.
q Throughout the ray-tracing process, the program tracks both the magnitude and the phase of the electromagnetic wave. Complex reflection and
transmission coefficients are computed at each incident point. This feature allows the system engineer to analyzed not only SISO (single input
single output) but also any diversity scheme and MIMO (multiple input multiple output) channels.

Simulation of LTE and Smart Cities
3G/4G LTE ad 4G are used in modern communication systems for mobile devices
in cities and towns around the globle.
3G – 5G uses high frequencies rangingin 500 MHz to 5 GHz.
MobileCDS is capable of simulating LTE/iOT Systems and we present a use case
with LTE

9. 9
Simulation of Multi-millimiter Wave / Radar
mmW is used in modern communication systems for RF Backhaul for Multi-Gigabit
links as well as characterization ofimages both in civil as militaryapplications.
mmW uses ultra-high frequencies rangingin 10’s to 100’s of GHz.
The advantage of millimeter wave radiation is that, in addition to clear weather
day and night operation, it can also be used in low visibility conditions such as in
smoke, fog, clouds and even sandstorms. In this way, millimeter wave imaging
expands our vision bylettingus “see” things under poor visibilitycondition
MobileCDS is capable of ultra-high frequency simulation and we will present a use
case at 6 and 28 GHz.

11. COMPUTATIONAL ENGINE
The computational window is used to initialize some
of the propagation parameters needed to run the
program. These include:
o The number of transmitted wavefronts.
o The number of bounces before a wavefront is
terminated.
o The propagation modes (LOS, reflection and
transmissions and diffraction).
o Outdoors only (faster) or both outdoor and
indoor.

12. Mobile-CDS includes a state of the art 3D
databases toolbox. It allows the user to
perform the following operations:
o Import 3D databases in one of the
following formats; Facet, KML and TIN.
o Combine terrain and 3D objects (buildings,
vehicles, trees, etc.).
o Crop a section of the 3D databases.
o Assign different electrical properties to
different objects included in the databases.
o Delete specific objects.
o Duplicate databases

hardcoded and user defined protocols
specifications. The program uses the protocol
specifications in order to estimate data rate and
throughput statistics in the simulated region.

16. MATERIAL PROPERTIES TOOLBOX
Mobile-CDS assigns
electrical properties to the
building materials in order
to compute the amount of
energy reflected,
transmitted and diffracted
as signals bounce within the
propagation environment.
Each material is
characterized by its complex
dielectric constant and
thickness.

18. Antenna Toolbox
Mobile-CDS uses 3D antenna patterns in all of its
simulations. The patterns are specified in term of
their complex Eqand Efelectric field components.
This allows the program to track both, the
magnitude and the phase of the signal as it
propagates through the environment. Patterns
generated by antenna manufacturers, measured in
an anechoic chamber or generated using an
electromagnetic solver such as XFDTD, can easily by
converted into .ant format and use in the simulation
in order to produce more accurate results.18.0 dBi TX antenna pattern. Both, TX and
RX patterns are represented by their
complex Etheta and Ephi electric fields
components.

19. Analysis and Post Processing
Mobile-CDS includes an analysis engine, which
allow it to carry out several post-processing
functions on the simulation data generated. These
are just a few:
o RF coverage.
o RMS-Delay estimates.
o Throughput calculations.
o Interference analysis.
In addition, the program outputs the results in an
enhanced file format, which allows the system
engineer to post-process the data using one of
several scripting languages such as Matlab or
Python.

33. CONCLUDING REMARKS
We believe the material presented would have an impact in your product design cycle.
The simulations included gives an indication of just some of the capabilities available in
Mobile-CDS. The power of the tool is greatly enhanced by post-processing the data
stored in an extended file format made available to the system engineer after each
run. Complex studies of diversity schemes (switch, time, frequency, gain, MRC), MIMO
channels and generation of empirical models for specific environments are readily
available.
Additionally, MobileCDS is suitable for testing at high GHz bands or even THz
depending on computing power, memory, and level of detail required.
However, it should be emphasize the capability this state of the art program has to
lower production cycle time and cost by avoiding costly and time consuming data
collection in the field.
