At the newest World Radio Convention 2023, held in November and December 2023 in Dubai, organized and hosted by the Worldwide Telecommunication Union (ITU), a consensus emerged amongst regulatory our bodies and business leaders to discover extra spectra for the subsequent era of cellular communication, formally labeled IMT-2030, also called 6G. Notably, the 14.8 to fifteen.35 GHz frequency vary has been earmarked for international examine. As well as, native companies just like the Federal Communications Fee (FCC) in the USA are additionally eyeing the higher 12 GHz band (12.7 to 13.25 GHz) for future wi-fi purposes.
In anticipation of those developments, Rohde & Schwarz, main provider of take a look at and measurement options to the wi-fi business, has enabled Qualcomm Applied sciences, a trailblazer in wi-fi system know-how, to show that the Giga-MIMO system for tomorrow’s infrastructure is prepared and efficient to function in these frequencies. It guarantees enhanced knowledge efficiency whereas providing protection corresponding to present 5G large MIMO networks operational at 3.5 GHz.
To validate the efficiency of this prototype, Qualcomm Applied sciences utilized the R&S SMW200A vector sign generator and R&S FSW sign and spectrum analyzer from Rohde & Schwarz. The setup included specialised firmware for the testing of various subcarrier spacings with wider sign bandwidths in comparison with right now’s 3GPP bodily layer specs. The broader bandwidths will in the end allow increased knowledge charges and decrease latency.
Andreas Pauly, Chief Expertise Officer at Rohde & Schwarz, mentioned: “We’re thrilled to increase our help of Qualcomm Applied sciences and discover the brand new frontier of cellular communications collectively. Our tailor-made take a look at options are instrumental in advancing analysis for 5G-Superior and 6G networks, and exploring the probabilities of the FR3 frequency vary lays the foundations for the success of tomorrow’s cellular purposes.”
Tingfang Ji, Vice President of Engineering at Qualcomm Wi-fi Analysis, Qualcomm Applied sciences, Inc., mentioned: “We’re dedicated to pioneering next-generation cellular applied sciences and are grateful to Rohde & Schwarz for its help in serving to to make this a actuality. Our efforts to allow Giga-MIMO in higher midband for wide-area protection assist to set the stage for 6G and a transformative leap in wi-fi communication.”
Demonstration of FR3 sign era and evaluation at MWC Barcelona
At MWC Barcelona, Rohde & Schwarz will show a excessive efficiency sign era and evaluation setup for early FR3 analysis, that includes the newest vector sign generator and analyzer merchandise. The setup consists of the model new R&S SMW200A, not solely with a brand new entrance panel and person interface but additionally vital enhancements in EVM efficiency. On the evaluation facet, the R&S FSVA3000 contains particular options like IQ noise cancellation to realize excellent EVM measurement efficiency because of a noise corrected measurement path. Devoted 5G indicators for FR3 are being generated and analyzed as a part of the demonstration.
Rohde & Schwarz will current its complete take a look at options for the cellular business together with a setup demonstrating high-performance sign era and evaluation for FR3 indicators on the Cell World Congress 2024. Guests can discover Rohde & Schwarz in corridor 5, sales space 5A80, on the Fira Gran By way of in Barcelona.
