testing 5g qoe: use cases, services and a new qoe paradigm (part 1)

march 28, 2019 | by jeremy carpenter

5g demands a new paradigm for measuring the quality of experience (qoe), particularly for mmtc and urllc use cases, as qoe has a different meaning in machine-type communication. explore how the emergence of 5g and the new cases and services it brings demand new network measuring approaches.

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?

machine learning in mobile network testing (part 1)

november 7, 2018 | by miguel román

telecom leaders believe that machine learning (ml) will be key to deriving and inferring user behavior and expectations. this blog series demonstrates our ml applications on drive test data by discussing specific use cases and customer benefits. to start, we will discuss artificial intelligence in general.

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.

5g: first independent 5g test network benchmark study (part 3)

august 29, 2018 | by arnd sibila

us-based signals research group (srg) trusts the prototype measurement system designed by rohde & schwarz to meet the aggressive timeline of early 5g adopters. learn about srg’s findings in the first independent 5g test network benchmark study using the r&s®tsma autonomous drive test scanner to collect valuable downlink performance metrics.

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.

how 4×4 mimo can boost your mobile network

july 4, 2018 | by michael lorenz

network densification and the introduction of new frequencies are cost-intensive and time-consuming. could the implementation of higher-order mimo features into existing radio networks meet the inexorable demand for more data volume? and how does 4x4 mimo boost data rates and deliver additional capacity gain, thereby improving legacy lte networks?

5g: initial 5gtf coverage measurements (part 2)

june 12, 2018 | by arnd sibila

the us operator verizon wireless trusts our 5gtf prototype measurement backpack solution to test signal quality and to measure the coverage of fixed wireless access (fwa) in the 28 ghz frequency band. before 3gpp, verizon wireless and partners created a pre-5g specification called 5g technical forum (5gtf).

5g: the role of mobile network testing on the path to 5g (part 1)

may 22, 2018 | by arnd sibila

long before commercial services are available, everyone is talking about 5g, creating a buzz and setting high expectations in the new standard. what’s the role of mobile network testing on the path to 5g? how can scanner measurements help operators pave the way to the next generation of mobile networks?
