This course focuses on teaching the skills and best practices needed for designing and delivering scalable, highly-reliable LTE roaming services.
In addition to lecture materials, this course includes real network configuration examples to ensure that participants apply what they learn and put their knowledge to practice in their work.
Upon completing all the topics contained in this course, participants are expected to sit for a certification exam at the end of the course.
Course materials and exam are developed and deliverd by Telefocal's LTE and Roaming subject matter experts.
