3G technologies ushered in the smartphone era through high-speed, mobile Internet access that revolutionized the way we live, interact, and consume information. At Qualcomm, our system-level inventions drove the introduction and evolution of 3G. And many of these technologies are essential to future mobile broadband enhancements in 4G LTE and 5G NR.
Our inventions solved the complex challenges that turned CDMA into world-changing technology and a commercially viable option for 2G, and ultimately led to CDMA becoming the basis for all 3G networks and the introduction of mobile broadband services. 3G evolved into two competing mobile broadband standards, both based on CDMA: CDMA2000/EV-DO and WCDMA/HSPA+.
The Magic of Mobile
May 14, 2018
In today’s wireless world, connecting to the Internet in seconds from virtually anywhere is a given. We pioneered EV-DO technologies that optimized mobile for data—blazing the trail for HSPA and making the magic of mobile broadband possible.
Introduction of data-only, data-optimized technologies (EV-DO, HSPA).
Use of higher-order modulation to get more bps per Hz for users with good signal quality.
Optimizations of system performance based on scheduling users when they have good radio signal conditions (with fairness).
We led the evolution and expansion of 3G with EV-DO Rev. B and HSPA+, enabling a consistent broadband experience and ubiquitous voice services with the introduction of 4G LTE. 3G advancement also introduced many mobile broadband technologies that are essential to 4G LTE.
Pioneering HSPA+ carrier aggregation for faster DL and UL speeds.
Advanced antenna techniques, including MIMO and Rx diversity.
Small cell technologies like range expansion pioneer heterogeneous networks (HetNets).
HSPA+ Multiflow offer a solution for cell edge performance improvement and dynamic load balancing.
