In the next 10 years, the telecommunications sector will be dominated by the deployment of pervasive networking available in a wide range of heterogeneous scenarios applying 5G (and beyond) technologies. SDN, NFV as well as Network Sliding Technologies used by 5G will provide a ''softwarization'' of the network functional elements, opening the ecosystem of network providers to a vast number of suppliers from traditional manufacturers to start-ups focusing on specialized functions. Due to the need to assert the expected interoperability of the introduction and evolution of this set of Network Functions, a set of validation tools is needed to explore traffic patterns according to different scenarios and thus allow the performance of the software modules to be evaluated. This research work presents the design of software tools that aim to provide a way for generating signaling and user traffic in 5G networks, enabling the definition of novel pure-software testing environments for 5G that includes real signaling and user traffic. The tools have been designed to support a set of testing signaling procedures that cover the basic main functioning of 5G networks and that allow for the transmission of user traffic over the network. The tools have been implemented and licensed as Open Source and have been validated through their deployment in a virtualized 5G environment that includes a 5G core network.

A Novel Mode-Stirred Reverberation Chamber Design for 5G Millimeter Wave Bands

et al. 2021

A novel mode-stirred reverberation chamber (RC) is designed and analyzed for millimeter wave bands. The size of the proposed RC with dimensions of 0.9 m◊0.9 m◊1.1 m is suitable for user equipment (UE) tests. Two Zshaped mode-stirrers are applied to generate a uniform field. To fulfill the communication and test requirements for user equipment, reference, measurement and link antennas with a large bandwidth are utilized, which can support both the frequency range (FR) 1 and FR2 bands of the 5G spectrum. The lowest usable frequency (LUF) and mode density were first calculated and examined. Then, the power transfer function (PTF) from 2 GHz to 40 GHz was obtained to verify the path loss. Three measurement campaigns were carried out to verify the accuracy of the RC. Firstly, the transmission power of the passive antenna for a conductive test was compared with the RC over the air (OTA) total radiated power (TRP) for single-tone signals. Then, signals with bandwidths of 100 MHz and 400 MHz were applied. A maximum power difference of only 0.8 dB was found in the above two experiments. Furthermore, the TRP for the same commercial 5G UE in both RC and compact antenna test range (CATR) systems was measured and compared. To the best of the authors' knowledge, this is the first work to provide TRP results for 5G millimeter wave bands in a RC. The test results show that the TRP values for the two systems are almost the same with a maximum deviation of 0.5 dB, while the time required to carry out tests using the RC is lower than that for the CATR system.
