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…

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

Everyone is talking about 5G. Long before commercial 5G services are even available, a myriad of articles, reports, presentations and speeches have been made public – creating a big buzz and 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…
