Detection and measurement of these base station cells is challenging because the measurement must achieve a high sensitivity while avoiding false alarms that result in detecting non-existing cells (i.e., ghost codes). With the use of non-standalone (NSA) and dynamic spectrum sharing, the 5G NR FR1 and corresponding LTE channel must be measured at the same time to ensure that both network links work as expected. Therefore, a reference measurement device such as a receiver or scanner is required, which provides a common ground for comparison. While it is possible to evaluate the performance of the network using a mobile phone, the disadvantage is measurement variation, as results vary depending on the chip set or installed software.

Frequency selective measurement methods of exposure to 5G base stations have been described, 9,10 emphasizing the need for code selective measurement methods, especially in networks with several base stations and with data traffic.Ī mobile network operator must evaluate the quality of the network to investigate network problems, unwanted interference or assessment of new base stations. Consequently, 5G base station deployment requires that the electrical field strength (V/m) is below the specific threshold for each country.

8ĥG and associated technologies such as beamforming and frequencies above 3 GHz have raised potential health concerns due to the human exposure to the electromagnetic field of base stations.

Measurements of arrival times enable verification of network synchronization aspects. Measurements of the channel impulse response result in deeper knowledge about the propagation of wireless signals in different environments, i.e., reflection, absorption and scattering in urban versus rural areas. 6,7 For example, measurements of received power enable verification of 5G NR cell beamforming and its impact on the coverage area. Throughout the entire chain of laboratory testing, field trials, network rollout, optimization and benchmarking, measurement tools for mobile network testing (MNT) are required to characterize the conditions of the wireless channel and network coverage in the field.

5G NR supports operation in two frequency ranges: FR1 below 7,125 MHz 4 and mmWave bands (FR2) between 24.25 and 52.6 GHz. These optimizations require many new technology components, including new frequency bands, beamforming support for synchronization and broadcast and multi-connectivity to enable the combination of 5G network elements with LTE. 1,2,3 The 5G NR specification allows optimization to reduce the latency and to significantly increase the data rate. A solution is proposed for each.ĥG wireless radio access technology, known as NR, contains more flexibility to address different usage scenarios. Next, it addresses two typical challenges: 1) finding carrier frequencies with SSBs and 2) network synchronization.

It starts with relevant background information about 5G NR and mobile network testing, followed by a description of a typical measurement methodology for the frequency ranges one (FR1) and two (FR2). This article describes a mobile network testing approach for 5G new radio (NR) using a passive scanner, which measures synchronization signal (SS)/physical broadcast channel (PBCH) blocks, or SSBs, broadcast from 5G NR base stations.
