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…

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…

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…

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…

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

Identifying NB-IoT carriers with a pure RF power scan is very difficult and sometimes impossible. After describing the benefits of NB-IoT MIB/SIB demodulation in the previous NB-IoT post, this post discusses the challenges in identifying NB-IoT carriers in the spectrum and offers solutions. The extended Automatic Channel Detection (ACD) feature finds and identifies NB-IoT carriers automatically and display the findings…

Machine learning in mobile network testing (part 1)

Artificial intelligence (AI) has vast applications in the telecom industry, from anomaly detection to network optimization and utilization; and AI could lead to various new revenue streams. Many telecom leaders believe that machine learning (ML) will be the key to derive and infer user behavior and expectations. It aims to increase the user’s quality of experience (QoE) and reduce customer…

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

3GPP Release 15 specifies the initial 5G standardization framework of the radio access network called 5G New Radio (5G NR). The standard contains a high degree of flexibility in radio parameters which complicates network measurements. However, Rohde & Schwarz has already conducted measurements in pre-commercial 5G NR trial networks with our commercially available 5G NR network measurement solution. We gained…

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

Signals Research Group trusts the prototype measurement system designed by Rohde & Schwarz to meet the aggressive timeline of early 5G adopters. The US-based research consultancy used the R&S®TSMA autonomous drive test scanner for their independent 5G test network benchmark study to collect downlink performance metrics for the Beam Reference Signals (BRS), including RSRP, CINR, RSRQ, PCI, etc., of 28 GHz…

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

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 in order to collect and analyze data from all available operators and cells in an NB-IoT network. Numerous NB-IoT field engineers shared their experiences, providing us with valuable feedback. This post summarizes our customers’ latest…
