Companies elevated downlink speeds over 20% through the use of the most recent 1024 QAM expertise
Samsung Electronics and Qualcomm Technologies, Inc. right this moment introduced that the businesses efficiently accomplished 1024 Quadrature Amplitude Modulation (QAM) checks for each Frequency Division Duplex (FDD) and Time Division Duplex (TDD) spectrum bands, marking an industry-first for FDD. This revolutionary milestone and collaboration exhibit the businesses’ dedication to supporting operators improve 5G throughput and enhance spectral effectivity of their networks.
QAM is a complicated modulation expertise to transmit information or info extra effectively. This straight pertains to what number of bits of knowledge could be delivered in every transmission. While 256 QAM is extensively utilized in business networks, Samsung and Qualcomm Technologies lately achieved the most recent 1024 QAM outlined in 3GPP Release 17 specs. This enhanced QAM expertise helps operators maximize their use of spectrum assets and permits cell customers to seamlessly get pleasure from varied cell companies akin to stay video streaming and on-line multi-player gaming, which require increased obtain speeds.
▲ The 1024 QAM check, carried out in Samsung’s R&D lab, resulted in over 20% achieve in downlink speeds
The check was carried out in Samsung’s R&D lab in Korea leveraging Samsung’s 5G vRAN software program and radios — every supporting 2.1GHz (FDD) and three.5GHz (TDD) bands — and Qualcomm Technologies’ cell phone form-factor check gadget outfitted with its newest Snapdragon® X75 5G Modem-RF System.
This is a big milestone as it’s the first time the {industry} has achieved 1024 QAM for FDD band. By utilizing 20MHz bandwidth, the businesses reached 485Mbps, reaching near-theoretical achieve. This downlink pace is greater than 20% increased than what is feasible with the present 256 QAM.
In addition, Samsung plans to finish its ongoing checks of 1024 QAM in conventional RAN as properly, and the expertise is anticipated to be commercially obtainable inside this 12 months.
“We believe enhancing spectral efficiency is essential in developing next-generation solutions. This achievement underscores Samsung’s ongoing commitment to push forward the frontiers of mobile technology,” stated Ji-Yun Seol, Vice President, Head of Product Strategy, Networks Business at Samsung Electronics. “Our collaborative efforts with Qualcomm Technologies have once again yielded impressive results, and we look forward to harnessing our combined expertise to drive network innovation.”
“We are honored to have collaborated with Samsung on this industry first achievement,” stated Sunil Patil, Vice President, Product Management, Qualcomm Technologies, Inc. “This accomplishment showcases our unwavering commitment to supporting operators in their efforts to enhance 5G throughput and boost spectral efficiency. By leveraging advanced QAM technology, we are empowering operators to maximize spectrum resources and deliver seamless, high-speed mobile services to 5G users.”
Late final 12 months, Samsung and Qualcomm Technologies achieved the world’s first simultaneous 5G 2x uplink and 4x downlink service aggregation for FDD spectrum. The corporations are persevering with the collaboration to push the boundaries of cell 5G expertise.
Samsung has pioneered the profitable supply of 5G end-to-end options, together with chipsets, radios and cores. Through ongoing analysis and improvement, Samsung drives the {industry} to advance 5G networks with its market-leading product portfolio, from vRAN 3.0, Open RAN, core to personal community options and AI-powered automation instruments. The firm presently offers revolutionary community options to cell operators that ship connectivity to a whole bunch of hundreds of thousands of customers worldwide.
