Telefocal Certified International Roaming Professional (TC-IRP)

Telefocal Certified International Roaming Professional

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/modules contained in this course, participants will sit for a certification exam at  the end of the course. The course materials and exam for this training are designed and delivered by Telefocal’s panel of LTE and International Roaming subject matter experts.

Certification Exam:

  • The LTE International roaming Certification tests a candidate’s knowledge of the skills required to understand and implement technologies, architecture fundamentals, and infrastructure that are needed for Long-Term Evolution (LTE) roaming between international networks.
  • The exam consists of Multi Choice Questionnaire. Passing score is 60% in order to get certified.

This course is designed for engineers who wish to become an expert in all aspects of designing, building, and supporting LTE roaming networks and services.
