Qualcomm, the technology juggernaut, has shattered records by achieving a groundbreaking data download speed of 7.5 Gbps on a 5G network, utilizing a frequency range reaching up to 6 GHz. This astounding accomplishment leaves typical mid-band (C-band) 5G network speeds of 350-450 Mbps in the dust. The feat was made possible through Qualcomm’s cutting-edge Snapdragon X75 5G Modem-RF system, set to grace smartphones hitting the market by year’s end.
The key to this triumph was the use of the 300 MHz band of the 5G standalone network (SA) spectrum. While many current 5G networks are non-autonomous, built atop existing LTE infrastructure, SA networks offer the full suite of 5G capabilities and a wider bandwidth.
To further amplify performance, four-carrier aggregation was employed, weaving four discrete 5G channels into a seamless tapestry of heightened bandwidth and capacity. This union not only bolstered capacity but significantly increased the downlink data rate, underpinning this remarkable feat.
Beyond these engineering marvels, Qualcomm employed other technical marvels in its quest for speed supremacy. The 1024 QAM modulation, superseding the conventional 256 QAM, allowed data packets to accommodate a wealth of information. The integration of Time Division Duplex (TDD) provided a unique twist, enabling the use of the same frequencies for uplink and downlink at different intervals.
This landmark achievement showcases Qualcomm’s relentless pursuit of innovation and technological prowess. As we gaze into the future, we anticipate these leaps to redefine the boundaries of possibility, ushering us into a new era of connectivity and data speed.
