Snapdragon X75 modem achieves world’s fastest 5G speed with sub-6GHz spectrum

Qualcomm has announced that the Snapdragon X75 5G Modem-RF System which was introduced earlier this year has set a new world record on sub-6 GHz spectrum, achieving a 7.5 Gbps downlink speed.

Conducted through device testing using a 5G standalone (SA) network configuration, this speed was reached by leveraging a total of 300MHz of spectrum, using 4x carrier aggregation (4xCA) with 4 TDD channels in one downlink connection, and 1024 quadrature amplitude modulation (QAM),  the company.

Aggregation of 4 TDD channels enables operators to combine their diverse spectrum assets to achieve higher data rates. In addition, 1024 QAM improves spectral efficiency by incorporating more data into each transmission, in comparison to 256 QAM, ultimately allowing for increased data throughput and improved spectrum efficiency.

These features enable future-ready devices so more demanding data applications, such as video streaming and downloads, online gaming and more, can run smoother than ever, for more users, said Qualcomm.

Snapdragon X75 is already sampling to customers, and the commercial devices expected to launch in the second half of 2023, said Qualcomm, so we can expect it in the flagship Snapdragon 8 Gen 3 chip, which should be introduced at the Snapdragon Tech Summit 2023 in October.

Regarding this achievement, Sunil Patil, vice president product management, Qualcomm Technologies, Inc, said:

Snapdragon X75 5G Modem-RF System is the smartest wireless modem we have ever created and is designed for the future, with a 5G Advanced ready architecture, made to help operators define the next generation of networks around the world. We look forward to continuing to work with industry leaders to power the best-in-class connectivity experiences and transform industries across consumer, enterprise and industrial use cases.
