The 5G network is a vast and complex world that cannot be built by one person or one organization alone. It requires the collective strength of teams and collaboration across industries. In the journey of 5G development, no single entity can achieve success in isolation—cooperation is key. Qualcomm has always understood this, and rather than closing its doors, it has actively partnered with global groups to drive the expansion of 5G worldwide. Whether it's setting industry standards, conducting testing, or moving toward productization, Qualcomm has consistently been at the forefront. The company leverages its technological expertise to fuel the growth of the 5G ecosystem, helping to shape what many call the "big earth" of 5G. **Inciting the 5G “Big Earth”: Qualcomm Leads the Way** While others are still discussing 5G, Qualcomm has already begun building the “Future Big World” of 5G. From early involvement in standard-setting to cutting-edge research and development, Qualcomm has taken a proactive role in shaping the future of wireless communication. Its efforts have not only accelerated the timeline for 5G deployment but also set the stage for a new era of connectivity. Long before 5G became a mainstream topic, Qualcomm was already laying the groundwork. The company has been deeply involved in the 3GPP (3rd Generation Partnership Project) process, contributing to the development of global 5G NR (New Radio) standards. In February 2017, Qualcomm joined forces with over 20 mobile industry leaders to push forward the large-scale trials and deployment of 5G NR. They established key milestones, including the completion of non-standalone (NSA) 5G standardization, which would support large-scale 5G trials starting in 2019. Today, Qualcomm has completed work on Release 14 of the 5G new air interface and is fully engaged in Release 15. Within R15, Qualcomm aims to first complete the non-standalone mode of the 5G new air interface, followed by standalone mode, ultimately achieving a fully operational next-generation core network. Looking ahead, Qualcomm will continue its work in R16 and R17, further evolving 5G technology. At the same time, LTE evolution will remain an important part of the R15 work. Qualcomm believes that the 5G new air interface standard in R15 will serve as the foundation for the next decade of technological innovation. **The Soul Weapon Chip: Driving Terminal and Network Adoption** At the heart of Qualcomm’s strategy is its advanced chip technology. The commercialization of 5G networks depends heavily on the adoption of 5G-enabled devices, and the chips inside those devices play a critical role. In 2016, Qualcomm launched the world’s first 5G modem—the Snapdragon X50 series—which supported multiple generations of wireless technology (2G/3G/4G/5G) in a single chip. It also supported the global 5G new air interface standard and Gigabit LTE. However, the initial version of the X50 supported only the 28 GHz millimeter wave band. In February 2017, Qualcomm expanded the X50 family to include support for both sub-6 GHz and multi-band millimeter wave spectrum, making it a truly global solution. This single-chip approach enabled seamless operation across all major wireless technologies. Just past October 2017, the Snapdragon X50 achieved gigabit speeds on the 28 GHz millimeter wave band, marking the first officially released 5G data connection. The X50 series is expected to power 5G smartphones and networks launched in the first half of 2019. Before 5G officially arrived, Gigabit LTE played a vital role in preparing the market. Qualcomm has also been pushing the boundaries of LTE, introducing the sixth-generation LTE modem, the Snapdragon X16, which delivered download speeds of up to 1 Gbps. Integrated into the Snapdragon 835 platform, it brought enhanced mobile experiences to consumers, supporting applications like VR/AR, cloud storage, and high-speed data access. In 2018, Qualcomm introduced the second-generation Gigabit LTE modem, the X20, which supported LTE Category 18 and achieved download speeds of up to 1.2 Gbps. Commercial devices using this chipset were expected to hit the market in the first half of 2018. **5G Prototype Systems: Pushing New Ideas and Making Dreams Real** Millimeter waves, which operate above 24 GHz, are seen as a key component of 5G. These high-frequency bands offer massive bandwidth, enabling data transfer rates of several gigabits per second and supporting dense spatial multiplexing to increase network capacity. By 2019, the industry hoped to deploy 5G new air interface technology—including millimeter waves—in mobile applications to meet growing demand for mobile broadband and support emerging use cases like immersive VR/AR. The enhanced mobile broadband provided by 5G would transform how people consume media, create content, and interact with digital experiences. In September 2017, Qualcomm launched a 5G new air interface millimeter wave prototype system to accelerate mobile deployment. This system operated in the mmWave band above 24 GHz, demonstrating the potential of 5G to deliver robust mobile broadband in real-world conditions. It also showcased Qualcomm’s optimized mmWave RF front-end design, addressing challenges such as signal blockage in handheld devices. Earlier that year, in June 2017, Qualcomm had already introduced a 5G new air interface prototype system operating below 6 GHz. This system was recognized as one of the "World Internet Leading Scientific and Technological Achievements" at the Third World Internet Conference. Later that year, Qualcomm also launched a 5G new air interface spectrum sharing prototype system and test platform. **Group Collaboration: Lighting Up 5G Around the World** Qualcomm understands that 5G cannot be built by one company alone. Collaboration is essential. On the path to global 5G deployment, Qualcomm has worked closely with partners around the world. In February 2017, Qualcomm announced a partnership with ZTE and China Mobile to conduct interoperability testing and OTA field tests based on the 5G new air interface specification. The tests were conducted on the 3.5GHz frequency band and were planned for the second half of 2017. In August, Qualcomm joined forces with China Telecom to build a 5G innovation demonstration network in Xiongxian County. In September, the company announced a collaboration with Nokia to promote the large-scale deployment of 5G new air interface technology. These partnerships reflect Qualcomm’s commitment to global 5G development. By working with leading operators such as AT&T, Vodafone, NTT DOCOMO, Telstra, and SK Telecom, Qualcomm is accelerating the pace of 5G commercialization worldwide.
