OURBACKGROUND

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

S.O.L Engineers.

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

RF Characterization created byMobileCDS

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.

Features

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 wallsdiffracted 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 terrainscan 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 Eqand Efcomponents. The antenna patterns can begeneratedusing an electromagnetic solver (XFDTD), anechoic chamber measurements or data provided by a vendor.

q Throughouttheray-tracingprocess,theprogramtracksboththemagnitude andthephase oftheelectromagneticwave.Complex reflectionandtransmission coefficients arecomputed ateachincidentpoint.Thisfeatureallowsthesystemengineertoanalyzednotonly SISO(single inputsingleoutput) butalsoanydiversityschemeandMIMO(multipleinputmultipleoutput)channels.

SimulationofLTEandSmartCities

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 ranging in 500 MHz to 5 GHz.

MobileCDS is capable of simulating LTE/iOT Systems and we present a use case

with LTE

9

SimulationofMulti-millimiterWave/Radar

mmW is used in modern communication systems for RF Backhaul for Multi-Gigabit

links as well as characterization of images both in civil as military applications.

mmW uses ultra-high frequencies ranging in 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 by lettingus “see” things under poor visibility condition

MobileCDS is capable of ultra-high frequency simulation and we will present a use

case at 6 and 28 GHz.
