Experimental test results of EMC between 5G and Radio relay links in millimeter band

Sharing Studies between 5G IoT Networks and Fixed Service in the 6425–7125 MHz Band with Monte Carlo Simulation Analysis

“…The simulation takes into account interference from both uplink and downlink of 5G. Figure 2 below presents a typical scenario of 5G downlink and uplink interference to a point-to-point fixed service station [6][7][8][9][10][11][12][13][14].…”

“…When it comes to simulation and spectrum management techniques and approaches, this work takes into account various works on that topic [4,5] that are commonly used in the studies in such organizations like ITU-R, CEPT and many others.. Earlier works on the matter of sharing studies have introduced the need defining compatibility conditions between 5G networks or networks of legacy standards and fixed service stations [6][7][8][9][10][11][12][13][14], at the same time these studies cannot be fully applied to 6425-7125 MHz because of the entirely different deployment between those two bands since propagation losses between 6 GHz and millimeter waves are significantly different, also millimeter-wave base stations have shorter antenna heights and the different number of antenna configurations which affect dramatically on the interference levels. In addition, these works include only interference study from BS but do not include the study of interference from UE, usually, commonly it is explained that since 5G uses TDD there is no need to study UE interference since it's normally negligible compared to the interference from BS, the authors of this paper believe that interference from UE needs to be studied anyway for the reason that in many cases operation of BS may be restricted depending on the regulators' needs, whereas UEs normally cannot be regulated, and in some local scenarios the interference from UEs can be comparable with BS interference.…”

Bandpass NGD function design for 5G microwave signal delay synchronization application

“…5G technological advancement is expected as a promising solution for future mobile communication [3]. However, the communication system using 5G wireless sensor networks (WSNs) may suffer from electromagnetic compatibility (EMC) issues, for example, due to the radio link signal interferences [4,5], EMC and massive Internet of Things (IoT) [6].…”
