5G NR network measurements

5G NR is the new radio access technology for the next generation mobile communication standard that is significantly different from LTE in the following characteristics:

  • New frequency bands below and above 6 GHz, promising globally available frequency ranges with the principle ones being: 3.4 to 4 GHz and 26 to 29 GHz.
  • Beamforming support for synchronization signals and broadcast channels
  • Wide flexibility of physical radio parameters such as channel bandwidth, subcarrier spacing and symbol duration

These characteristics have an impact on the signal propagation and consequently increase the need for accurate coverage measurements to enable and verify correct 5G NR network planning and the rollout of base stations.

The Network Coverage Challenge

As for all new technologies, coverage is the most important question that has to be answered with confidence

This 5G NR coverage challenge impacts all phases of the lifecycle of 5G NR networks:

  • Before network rollout (pre-installation phase): 5G NR network measurements in a pre-commercial network trial are the only way to provide insights into the performance of the new technology and to overcome uncertainties before commercial launch.
  • At commercial network rollout (installation phase): 5G NR network measurements verify 5G NR network planning and site installation, for example to determine if the planned cluster and network coverage will be successful.
  • In network optimization phase: 5G NR network measurements can verify the handover areas between sites, cells and beams and at the same time limit the interference between cells to increase the provided capacity.
  • Trouble shooting: 5G NR network measurements help find root causes of potential problems in networks, e.g. coverage holes, high interference causing too low capacity, etc.
  • Benchmarking: 5G NR network measurements will also support benchmarking campaigns in the future in order to compare different operators’ 5G NR networks.

5G NR network measurement solutions from Rohde & Schwarz

Beam-specific 5G NR coverage measurements

This 5G NR test solution is based on the field-proven R&S®ROMES drive test software for measuring network quality with scanners and test smartphones and covers all cellular technologies.

  • In combination with the scanners R&S®TSME6 and R&S®TSMA6, R&S®ROMES offers the first 5G NR network measurement solution that measures true 5G NR network coverage.
  • The solution also verifies the impact of beamforming for synch signals and broadcast channels.
  • R&S®ROMES drive test software is designed to connect 5G NR USB dongles or other pre-commercial devices to monitor the 5G NR device / network interaction and execute UL tests. It is a universal network optimization tool for collecting and analyzing 5G NR data.

This Rohde & Schwarz 5G NR network measurement solutions has been shortlisted for the Global Telecoms Award 2018 in the 5G category called “Advancing the road to 5G”.

  • 5G NR network rollout is now – let’s test!

    The 5G NR standard (3GPP Release 15) 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 interesting insights into the new technology’s performance, capabilities and frequency bands.

    Signals Research Group relies on the prototype measurement system designed by Rohde & Schwarz to meet the aggressive timeline of early 5G adopters. In a Verizon Wireless 28 GHz trial network R&S®TSMA autonomous drive test scanners were used to collect downlink performance metrics for the beam reference signals (BRS), including RSRP, CINR, RSRQ, PCI, etc.
