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).

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

Small cell technologies like range expansion pioneer heterogeneous networks (HetNets).
