Several standards exist for testing the radiated “over air” (OTA) performance of 5G User Equipment (UE) devices. All these are limited to a Single-Input Single-Output (SISO) evaluation device. With networks and devices already deployed in operation, it becomes necessary develop realistic Multiple-Input Multiple-Output (MIMO) beamforming metrics UEs. Since most important feature is beamforming, ...

To benchmark the performance of Bus System (BS), Performance Measurement Systems (PMSs) should be used. In that regard, this contribution reviews advancement standard PMSs used globally: Key Indicators (KPIs). This research will further identify BS has a record effective throughout their operations. With reference from experiences in benchmarking, we have presented literature review KPIs and ev...
