- Samsung and Qualcomm have successfully increased 5G downlink speed by 20% using 1024 Quadrature Amplitude Modulation (QAM) for both Frequency Division Duplex (FDD) and Time Division Duplex (TDD) spectrum bands.
- 1024QAM is an advanced modulation technology that allows for more efficient data transmission, enabling higher download speeds necessary for services like live video streaming and online gaming.
- The tests, conducted at Samsung’s R&D lab in Korea, utilized Samsung’s 5G vRAN software and radios, along with Qualcomm’s Snapdragon X75 5G Modem, showcasing the potential for future mobile devices, including the Samsung Galaxy S24 series and the upcoming iPhone 16 line.
- Carrier Aggregation, a technique used to increase data transfer rates, played a crucial role in achieving these higher speeds, demonstrating the importance of advanced technologies in enhancing 5G throughput and spectral efficiency.

Oh boy, Samsung and Qualcomm have done it again! Just last week, they dropped the news. They’ve cranked up 5G downlink speed by a whopping 20%. How? By acing tests for 1024 Quadrature Amplitude Modulation (QAM) across both FDD and TDD spectrum bands.
Now, for the uninitiated, FDD and TDD might sound like alphabet soup. But here’s the scoop: FDD juggles two different frequencies for sending and receiving data. TDD? It’s more of a time-management pro, using a single frequency and splitting time between transmitting and receiving.
QAM’s the real MVP here, though. It’s all about packing more data into each transmission. Think of it as upgrading from a cozy sedan to a spacious SUV. While the tech world has been cruising with 256QAM, Samsung and Qualcomm are pushing the pedal to the metal with 1024QAM.
And Samsung’s got the receipts. They’re saying this turbocharged QAM tech is a game-changer for operators. It’s like giving them a magic wand to wave over their spectrum resources. For us mortals, it means smoother live video streams and glitch-free gaming. Imagine not having to watch that buffering icon spin during the climax of your favorite show.
The magic happened in Sammy’s lab in Korea. They used their own 5G vRAN software and radios tuned to 2.1GHz (FDD) and 3.5GHz (TDD) bands. Qualcomm chipped in with a device kitted out with the Snapdragon X75 5G Modem. Yep, that’s the same beast powering the Samsung Galaxy S24 series. And rumor has it, the iPhone 16’s gonna get in on the action too.
But wait, there’s more. Samsung and Qualcomm aren’t just about breaking their own records. Last year, they pulled off a stunt with simultaneous 5G 2x uplink and 4x downlink carrier aggregation for FDD spectrum. It’s like adding an extra lane to our one-lane internet highway. Suddenly, data’s zooming along at breakneck speeds.
Sunil Patil from Qualcomm’s got something to say too. He’s pretty chuffed about this “industry first achievement.” It’s all about giving operators the tools to supercharge 5G throughput and make the most of their spectrum. For us users? It’s about getting our hands on lightning-fast mobile services without a hitch.
So, what’s the takeaway? Samsung and Qualcomm are on a mission to make our 5G experience faster and smoother. And with these tech titans at the helm, who knows what’s next? One thing’s for sure: the future of mobile internet looks blazing fast.
