  2. 2. 2 OUR BACKGROUND 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

  5. 5. 5 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. INTRODUCTION mobile CDS

  7. 7. Features 7 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.
  8. 8. 8 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. 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.

  18. 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. 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. 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.
