After more than a decade in the telecommunications industry, Yunuen Wagner, Product Marketing Manager, is still amazed by how fast communication technologies change, evolve, and adapt. “Today, we have a whole network in our pockets”, says the expert in installation and field service solutions with a BSc in electronics and communications engineering. Determined to support network operators and their subcontractors in their endeavors to keep a network up and running, Yunuen shares her expertise in interference hunting and offers practical tips on how to keep interferers out and revenue in.

Are you having trouble spotting interference in your 5G NR TDD network?

July 31, 2019 | by Yunuen Wagner

5G opens the door to a completely new range of applications and services. From an interference-hunting point of view, what are the implications of 5G? What are the particular challenges when hunting interference in 5G TDD networks? And how do you separate the UL and DL slots on your device’s display?

Interference hunting: The real meaning of automatic direction finding

November 13, 2017 | by Yunuen Wagner

The need for interference hunting in mobile networks is steadily increasing. And field engineers often ask us which tool we would recommend in order to be successful in the field. With decades of expertise, what we can say for sure is that it depends: the right tool for successful field service operations depends on the source of interference. Sources are manifold, but with the most suitable tool, they are easy to locate.
