About this course
Refresh your RF interference mitigation knowledge through 40 hours of continuing education.

Revisit spectrum analyzer operation, field investigation, filters and amplifiers, and regulatory documentation practices used in public safety, cellular, and other wireless environments. Complete the course activities and assessments, retain your completion records, and confirm the applicable renewal requirements with ETA International.
