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…

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…

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…

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…

5G: initial 5GTF coverage measurements (part 2)

The US operator Verizon Wireless targets fixed wireless access (FWA) in the 28 GHz frequency band. With partners, they created a pre-5G specification called 5G Technical Forum (5GTF). The business case depends on the number of households that can be connected to a certain number of base stations and still provide a suitably high data throughput. For the required signal…
