OTA Testing in 5G NR: Challenges, Solutions & Best Practices
Radio testing of base stations or User Equipment (UE) was established with the early 2G systems based primarily on conducted connections.
Even on a component level usually an RF connector was available, allowing connection of a test instrument to measure the metrics of interest.
Why do 5G devices and base stations need to be tested Over-The-Air (OTA)? What does a typical OTA test environment consist of?
What is the Quiet Zone (QZ)? Which test metrics does 3GPP specify for 5G OTA testing? How can we measure them?
This white paper addresses all these questions.
