Network measurements with drones: The next step to a connected sky
In the era of Internet of Things (IoT), one of the most urgently discussed topics concerns the deployment of Unmanned Aerial Vehicles (UAVs) to automate different commercial applications, ranging from simple mail delivery to offshore islands to more sophisticated aerial taxis. This blog post shows the results of mobile network measurements conducted with drones, which serve as the basis for…Read More
Network Performance Score: Templates for easy support in all products
The initial blog post about the standardized Network Performance Score (NPS) discusses the demand for an efficient calculation method of an overall score that reflects the perceived technical performance of a network or one of its subsets such as region, period, or technology. The score considers and weights the main key performance indicators (KPIs) for a wide range of services,…Read More
Are you having trouble spotting interference in your 5G NR TDD network?
Isn’t it fascinating? A new technology is making its way to the field. 5G NR rollouts are popping up all over the world. New bands (cmWave and mmWave), beamforming, ultra-low latency, higher data rates, ultra-reliability and so much more. 5G NR opens the door to a completely new range of applications and services! From an interference-hunting point of view, what…Read More
Impressions from managed services team benchmarking Africa
We have extended our traditional business focus from supplying mobile network testing solutions to being a fully-fledged managed services provider of benchmarking campaigns. In April 2018, Rohde & Schwarz created the managed services team to run large-scale benchmarking projects such as the one commissioned by the South African MTN Group. Besides figuring out logistics, infrastructure, topography and climate, the team…Read More
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)
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)
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)
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
