NB-IoT field test: Measuring NB-IoT underground
Singapore was among the first countries to deploy a nationwide narrowband Internet of Things (NB-IoT) network in 2018. In this blog post, we will share an NB-IoT field test procedure, including the results from NB-IoT measurements underground. “The Internet of Things is a key technology area for growth which will drive Singapore’s Digital Economy for a Smart Nation. We encourage…Read More
Machine learning use case: Call Stability Score (part 2)
In our previous post about machine learning (ML), we introduced the topic of artificial intelligence (AI) and hinted at the typical deep learning pipeline that is needed to apply ML on data collected with mobile network testing solutions from Rohde & Schwarz. In this post, we will demonstrate how we can leverage ML to extract more value out of the…Read More
Testing 5G QoE: The role of standardization organizations (part 3/3)
The previous parts of this blog series drew the conclusion that the critical nature of some applications demands that solutions for testing 5G QoE must be independent, transparent and traceable to certified international standards and not aligned to proprietary techniques or individual network equipment vendors. The more one considers the mission-critical applications arising from 5G cases, the more it reinforces…Read More
Testing 5G QoE: Defining and measuring 5G QoE test cases (part 2/3)
In part one of this blog series, we established that an expanded test methodology with new test cases is required to characterize the quality of experience (QoE) of 5G networks. Let’s now take a closer look at how to define and set up QoE test cases for these new “user” experiences. First, we need to understand the requirements of the…Read More
Testing 5G QoE: Use cases, services and a new QoE paradigm (part 1/3)
Visibility of subscribers’ quality of experience is something operators have sought to measure since the early days of mobile networks. In this three-part blog series, we consider the emergence of 5G, the new use cases and services it brings, and the necessity to rethink the approach to measuring network performance and the quality of experience (QoE) of 5G networks. From…Read More
Webinar report: 5G NR network deployment is now – let’s test!
With 5G NR network rollout clearly on the horizon, network operators worldwide are planning pre-commercial network trials. The target is to overcome the challenge of a more demanding and complex air interface and deliver the commercial and technical benefits offered by 5G. In recent posts about 5G network measurements, we discussed the challenges of and the test solutions for some…Read More
Spectrum clearance: Prepare your 5G NR spectrum for deployment
RF interference is one of the largest contributors to poor network performance. It manifests itself in dropped calls and low data throughput rates. When you invest in new bands to improve network performance and then get less than 50% of the expected performance improvement, it is time to tackle the problem head on. In LTE, for every 10 dB less…Read More
Network Performance Score: initiate improvements with a QoE-centric score
There are various scores, as in scoring methods, claiming to measure the performance of mobile networks on the market. Some scores are based on plain technical metrics, others on quality of experience (QoE) measurements or surveys. Which score should a mobile network operator (MNO) choose? The one providing the highest score? The cheapest one? The one based on technical scores…Read More
Quality of experience: are you really taking care of it in your mobile network?
Quality of experience (QoE) is crucial for the success of mobile network operators because subscribers are increasingly sensitive to the perceived quality of applications in mobile networks. Operators will only grow their subscriber base if they can lure subscribers from competing operators by offering a better perceived QoE. In a recent webinar, we provocatively asked the question “Are you really…Read More
The world’s first 5G NR network measurement solution
Rohde & Schwarz is pioneering 5G New Radio (5G NR) network measurements with the world’s first commercially available 5G NR network measurement solution. This solution enables users in the 5G network ecosystem as well as regulators to measure the 5G NR network coverage accurately – one of the biggest challenges in network planning. more...
