Rohde & Schwarz has enabled Qualcomm Technologies to demonstrate that the giga-MIMO system for tomorrow’s infrastructure is ready and effective to operate in the FR3 frequencies. It promises enhanced data performance while offering coverage comparable to current 5G massive MIMO networks operational at 3.5 GHz.
FR3, which is also known as the upper-midband, spanning 7.125 GHz to 24.25 GHz, will open a new frontier for mobile communication technology. Rohde & Schwarz technology plays a key role in enabling Qualcomm Technologies to show the readiness and effectiveness of the latest RF modem technology for FR3.
To validate the performance of this prototype, Qualcomm Technologies utilised the R&S SMW200A vector signal generator and R&S FSW signal and spectrum analyser from Rohde & Schwarz. The set-up included specialised firmware for the testing of different subcarrier spacings with wider signal bandwidths compared to today’s 3rd Generation Partnership Project physical layer specifications. Wider bandwidths will ultimately enable higher data rates and lower latency.
