On October 17, 2017, Qualcomm made a significant breakthrough by successfully establishing the first 5G data connection using its 5G modem chipset designed for mobile devices. The Snapdragon X50 5G modem chip enabled high-speed gigabit connectivity in the 28 GHz millimeter-wave band, marking a major step forward in the evolution of cellular technology and paving the way for future 5G-enabled devices.
In addition to this achievement, Qualcomm introduced its first 5G smartphone reference design, aimed at testing and optimizing 5G performance for power efficiency and device size. This move showcased Qualcomm’s commitment to bringing 5G technology to market faster and more efficiently.
Christiano Amon, Executive Vice President and President of Qualcomm's CDMA Technologies Group, emphasized the importance of this milestone: “Based on the Snapdragon X50 5G modem chipset, the world’s first officially released 5G data connection in the 28 GHz millimeter wave band truly highlights Qualcomm’s leadership in 5G and its deep integration into mobile connectivity. This achievement, along with our 5G smartphone reference design, demonstrates how we are driving the development of 5G new air interface technology to enhance the global mobile broadband experience.â€
The demonstration was conducted at Qualcomm’s lab in San Diego, where the gigabit download speed was achieved using multiple 100 MHz 5G carriers over the 28 GHz millimeter wave band. This new air interface technology represents a cutting-edge advancement in mobile communications, promising a next-generation user experience and significantly boosting network capacity.
The demonstration also included the SDR051 millimeter-wave RF transceiver IC from Qualcomm, alongside Keysight Technologies’ 5G protocol development kit and UXM 5G Wireless Test Platform. These tools helped validate the performance and readiness of 5G technology for real-world deployment.
Last year, Qualcomm became the first company to release a 5G modem chipset, showcasing its ability to transition from concept to functional chips in under 12 months. This rapid development cycle reflects Qualcomm’s long-standing leadership in cellular technology, now extended to 5G. Through extensive collaboration with global operators, network infrastructure providers, and industry partners, Qualcomm has played a key role in advancing the pre-commercialization of 5G technology.
The Snapdragon X50 5G modem series is expected to support commercial 5G smartphones and networks starting in the first half of 2019, signaling a new era of mobile connectivity and innovation.
