Interference hunting in cities: Choose angle of arrival over power

Interference hunting in cities: Choose angle of arrival over power

October 24, 2018 | by Jeremy Carpenter

The urban RF environment is very demanding – densely packed with a myriad of cellular and non-cellular transmitters, interfering emitters, and inconveniently located building. This post explains why it pays to focus on the angle of arrival (AOA) method regarding speed, accuracy, and effectiveness when hunting interference in urban areas.

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.

PIM testing: Best practices in a nutshell

August 3, 2017 | by Yunuen Wagner

When it comes to PIM testing, the necessary steps to identify passive intermodulation (PIM) and locate its source are similar to interference hunting. In the end, PIM is an internal source of interference and can have a significant impact on network performance.
