LTE RF Design Certification Boot Camp
Your network’s future air interface is LTE. This generation of
technology was named originally for its “Long Term Evolution”, but
its implementation is now coming in the short term.
The RF Design for an OFDMA-based wide-channel system like LTE has some
important new twists, when compared to 2G and 3G technologies.
Noise floors, interference considerations, and frequency reuse with
Resource Blocks all calculate in new and different ways, when
contrasted to the good old CDMA networks.
Get yourself prepared for your next RF Design project by hearing about the new tricks from
the trusted expert team at LEVER.
This course is hands-on throughout, allowing you to exercise your
new skills. We’ll review a few RF Design principles with hands-on laptop
spreadsheet exercises at the start. Then we’ll model RF
propagation and its impact on network and backhaul design, with
complex network models. The course culminates in a case study
using the EDX Wireless SignalPro® RF propagation analysis tool,
with which you will design an LTE network for a sample community.
Get hands-on with your laptop and get ready to master the tools!
Certification Exam
At the end of the course, you’ll have the chance to certify your LTE RF Design skills by challenging the Certified OFDMA RF Designer (CORD™) exam.
The exam features practical hands-on exercises in addition to testing relevant knowledge. Successful students will be licensed the use of the CORD logo with your unique certification number and the “CORD Focus on LTE” designation.
Distinguish your skills in the wireless industry and advance your career with the CORD certification.
