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…

HetNets/Small cells: reliable small cell planning (part 2 of 4)

Reliable planning of small cells is essential for important and critical deployments. Consider hospitals, manufacturing facilities or VIP (CxO) office floors and meeting rooms (the list of examples is endless). Successful and cost-effective planning, and with it small cell deployments, require planning tools that ensure highest reliability and accuracy. This, however, is not always the case as floor plans might…
