Mobile CDS or Mobile Computer Deterministic Simulator is an RF Propagation
and Simulation Environment that was created after many years of R&D in the
areas of electromagnetics and mobile communications. Mobile CDS is a copyright
software package created by S.O.L Wireless, LLC and now represented by EGLA
COMMUNICATIONS. This tools is the result of several years of R&D conducted by
EGLA COMMUNICATIONS uses Mobile CDS, provides hosting in its cloud
environment, and integrates its simulation RF paremeters with MobileCAD.
MobileCAD is a wireless emulation patented tool (7231330) that generates LTE /
Smart Cities Simulation environments with base stations and mobile phones with

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
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.
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
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
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.
