2. Who am I?
Dr. Edwin Hernandez has a PhD in Computer
Engineering from the University of Florida with
10 issued patents and publications. His
expertise is on wireless communications,
media, and emulation/simulation.
He has been working on Mobile Computing since
1999 and in simulations that include the NS-2 and
the RAMON emulator both generation massive
amounts of data.
His experience in Big data spans from the days prior to
the conception of the name and distributed computing
was used to solve the same problem

4. The RF Propagation Problem
They suffer path loss due to trees,
Buildings, cars, our hands
Some other signals, Reflect
Signals propagate, some diffract
5. Proliferation of Devices and Devices and more…
Proper dimensioning of networks, devices, is key
RF is more complex with 4G and
Even more with 5G
Millions of iPhones, Androids, iOT

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 by MobileCDS

23. • Tools
• Visual Studio C/C++ for RayTracing Simulation
• Python
• Hadoop – Parallel Cluster
• MapReduce – Could be done in AMAZON WEB SERVICES
• OpenCL (GPU is better for ray simulation) – Like a video game
• “Open Computing Language (OpenCL) is a framework for writing programs that execute across heterogeneous platforms consisting of
central processing units (CPUs), graphics processing units (GPUs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs)
and other processors or hardware accelerators.
Big Data Analysis Required
Observations
• Simulations can be done at multiple frequencies
from 100MHz to 100GHz or higher depending on
CPUs/GPUs
25. Parallelize with Hadoop
• Tools
• Python-based Tools
• Process the TXT/SV files
• Windows C/C++ OpenCL
26. Parallelize with Hadoop/Analysis of the Protocol
Analyse a huge matrix of <AntennaiD, x,y,z,RSSI, RMS Delay, BER, etc>
All points in the map then need to map to a certain protocol 4G/LTE
