NB-IoT: How to find NB-IoT carriers in the spectrum (part 6)

November 21, 2018 | by Gregor Tomic

NB-IoT carriers are very difficult, if not impossible, to find. The Automatic Channel Detection (ACD) feature in R&S®ROMES4 does the job automatically. But, what makes finding and identifying NB-IoT carriers so difficult in the first place? And, what implementation modes are there, and how do they differ from one another?

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.

Combined engineering and benchmarking measurements add value

April 5, 2018 | by Andreas Sprachtholz

Different mobile network measurement tools target different measurement scenarios. One might target quality of experience (QoE) and quality of service (QoS), another RF conditions. By combining detailed scanner data and user equipment measurements and tests, users can easily exchange measurement data between the benchmarking, optimization, and engineering worlds.
