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.
