Qualcomm Achieves World’s Fastest 5G at 7.5 Gbps with Sub-6GHz Bands, Using Snapdragon X75 5G Modem-RF System

wccftech.com:

Qualcomm has announced today that its flagship Snapdragon X75 5G Modem-RF system has managed to break another carrier of download speed as it has managed to set a new world record while using the sub-6GHz spectrum. The modem managed to achieve a whopping 7.5 Gbps downlink speed.

Snapdragon X75 was announced back at MWC earlier this year in February and serves as the successor to the impressive X70 that is found in the Galaxy S23 series and other Snapdragon 8 Gen 2 power devices. Qualcomm's latest test proves that the company is still looking for breakthrough performance and striving for the best of its hardware.

Now, for those wondering, Qualcomm undertook this impressive test using a 5G standalone (SA) network, and the impressive 7.5Gbps speed was achieved by leveraging 300Mhz of a spectrum and with four carrier aggregation (CA), and four TDD channels, all running in a single downlink connection along with a 1,024 quadrature amplitude modulation (QAM). All of this combined allowed the Snapdragon X75 to achieve this impressive downlink.

So, how does all of this work? Well, Qualcomm was kind enough to give us an insight. Combining 4 TDD channels allow the operators to combine various assets from the spectrums they have access to, and this allows for a higher data rate. Additionally, using 1,024 QAM instead of 256 QAM helps improve efficiency as it includes more data into each transmission that is set, this results in increased throughput and also works on improving the overall efficiency of the entire spectrum.

Qualcomm has talked about how all of these capabilities of the latest Snapdragon X75 modem will allow for a much better user experience, faster download speeds, better network handling, efficiency, and more. Simply
