5G NR network measurements

5G network testing

5G mobile 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 44GHz.
  • 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.

How to test a mobile network

The Network Coverage and Performance Challenge

Besides coverage the communication industry's focus is on Network Performance

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

  • At commercial network rollout (installation phase): 5G NR network measurements are essential for site testing and acceptance. Performance tuning is important due to the high degree of flexibility with 5G to bring the network performance to the planned level. Network Synchronization to limit interference (in TDD mode) and electro-magnetic field (EMF) measurements to prove that radiation is below a certain threshold are critical deployment topics.
  • 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: In benchmarking campaigns, different operators’ 5G NR networks are copmpared using the ETSI-harmonized method defined in ETSI TR 103 559. Please see our Network Performance Score webpage.

Private Networks - Campus Networks - Smart Factory

5G capabilities defined by 3GPP Rel. 16, 17, ff enable the deployment of private networks with an increased quality level - smart factories (Industry 4.0) are an example to provide an agile, adaptable, and automated manufacturing and warehouse environment. Accurate and insightful testing at every phase of the network lifecycle enables a faster rollout, efficient use of network resources, and awareness of issues before they become critical.

Demystifying 5G – Where 5G waveform candidates lose their advantage

5G waveform candidates, such as FBMC, UFMC and GFDM, are designed to overcome limitations of LTE. For example, FBMC, UFMC and GFDM outperform LTE in spectral regrowth.
