Testing 5G QoE: Defining and measuring 5G QoE test cases (part 2)

April 3, 2019 | by Jeremy Carpenter

Without knowing the underlying service and device requirements, network quality engineers do not know what aspects and metrics to treat as important KPIs. How do you define and set up quality of experience (QoE) test cases for new “user” experiences such as for sensors in an industrial IoT deployment?

Spectrum clearance: Prepare your 5G NR spectrum for deployment

February 6, 2019 | by Peter Busch

RF interference is one of the largest contributors to poor network performance, manifesting itself in dropped calls and low data throughput rates. Explore how to prepare your spectrum for 5G deployment by starting RF interference hunting and spectral clearance in LTE networks with a more automated approach.

Network Performance Score: Initiate improvements with a QoE-centric score

January 17, 2019 | by Arnd Sibila

The Network Performance Score (NPS) is a QoE-centric score based on the harmonizing and integrative scoring methodology for end-to-end QoS benchmarking and scoring published by ETSI. The NPS integrates the main KPIs of the most popular services into a single score that describes network performance from a true end-user perspective.

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.

5G NR network rollout is now – let’s test! (part 4)

September 12, 2018 | by Arnd Sibila

The first 5G standard, specified in the 3GPP Release 15, contains a high degree of flexibility in radio parameters that complicates network measurements. We conducted measurements in pre-commercial 5G trial networks with our commercially available 5G NR network measurement solution and gained early insights into performance, capabilities, and frequency band.

NB-IoT network insights through MIB/SIB demodulation (part 5)

August 10, 2018 | by Andreas Spachtholz

Our scanner-based solution to measure coverage in NB-IoT networks pioneered NB-IoT field measurements in 2017. Since then, thousands of kilometers have been driven and walked to collect and analyze data from all available operators and cells in an NB-IoT network. This post summarizes our customers’ key requirements and our answers.
