3G sparked the mobile broadband revolution.

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.

CDMA, pioneered by Qualcomm, is the foundation to 3G.

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


Delivering high-speed Internet access to your smartphone.

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. 

Data-optimized channel

Introduction of data-only, data-optimized technologies (EV-DO, HSPA).

Adaptive modulation

Use of higher-order modulation to get more bps per Hz for users with good signal quality. 

Opportunistic scheduling

Optimizations of system performance based on scheduling users when they have good radio signal conditions (with fairness).

Driving the evolution of 3G and setting the stage for 4G LTE.

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.

Our inventions drove the evolution of 3G that are essential to 4G LTE leadership.

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.
