Effective October 1, 2012, QUALCOMM Incorporated completed a corporate reorganization in which the assets of certain of its businesses and groups, as well as the stock of certain of its direct and indirect subsidiaries, were contributed to Qualcomm Technologies, Inc. (QTI), a wholly-owned subsidiary of QUALCOMM Incorporated. Learn more about these changes

Racing Toward 1000x with Sprint and NASCAR

Sprint, NASCAR and Qualcomm Technologies do some joint "hot-lap testing" of the hyper-dense small cells concept and QTI's UltraSON suite of features.

Qualcomm’s CnE Brings “Smarts” to 3G/4G Wi-Fi Seamless Interworking

Have you ever been frustrated when you connect to a Wi-Fi hotspot and its speed is slower than what you had with 3G/4G? Or even worse, once connected to this slow Wi-Fi, your smartphone doesn’t even try to fetch data from 3G/4G? Or how about when you see a strong Wi-Fi signal only to realize that there is no Internet connectivity or there is a firewall?

Delivering on the 1000x Small Cell Challenge – FSM99xx

Qualcomm’s march toward 1000x data challenge just got a shot in the arm—the FSM99xx family of chipsets. This expands our small cell portfolio and brings our vision of more efficient and cost-effective small cells one step closer.

Crossing over between 3G/4G and Wi-Fi – Seamless and Robust

Not a long ago, when we started talking about small cells, the first question we would always hear was “why do we need small cells, when we have Wi-Fi?” But that has rapidly evolved into “how can we ensure that the interworking between 3G/4G and Wi-Fi is robust and seamless?”

The interworking becomes even more crucial considering the looming 1000x challenge, in which Qualcomm envisions dense deployments of small cells, most of which are integrated with Wi-Fi.

Getting “Opportunistic” with Small Cells

When it comes to wireless mobile networks, it is a heterogeneous world out there—there are a large number of small cells interspersed with macro cells. HSPA+ and LTE Advanced incorporate many techniques that effectively address the interference generated by such heterogeneous networks (HetNets), some of which are available today.

Evolving your voice – VoLTE, WCDMA+ and more

Quick question for you—what technology do you use when you make a voice call on your shiny new 4G LTE smartphone? Answer - 3G, and in some cases even 2G!

HD Voice – “Hear me loud and clear”

In today’s data crazy, texting, tweeting, socially networked world, I think people still value a good “clear” voice conversation. Don’t you agree? Even more importantly, a large portion of mobile operator revenues come from voice services. And as usual, we at Qualcomm are at it again, bringing the best possible voice experience through our HD Voice offerings. So much so that Sprint announced their first HD Voice device running on Snapdragon recently.

Showcasing the future of 3G/4G at MWC

Over the last few months, we were hard at work on envisioning, developing, prototyping and testing the newest enhancements of 3G/4G technologies. And now, we are proud to say that we’re ready to demonstrate them in the flesh. However, you will have to wait until Feb 27th to see them live in action!

Is meeting data demand child’s play?

Would you believe that meeting data demand can be as easy as child’s play? No? Check out this video (after reading my blog of course)!

Marching toward femto networks!

During my recent talk about small cells and their evolution toward higher coverage, capacity and reach, a listener asked me, “Isn’t that what today’s picocells offer?” The answer is, “Exactly!” As we move toward femto networks, femtos will be used as traditional picocells, combining the plug and play benefit of femto architecture with larger coverage and capacity of picocells. Our recent announcement of femto chipsets supporting up to 32 users is a major step in that direction.

LTE TDD – The joy of coming from behind and winning

If you want to know the feeling of coming from behind to win the race, just ask these guys – Mobily and STC. While their bigger cohorts in India and China are still waiting, they launched the world’s first LTE TDD commercial networks in Saudi Arabia.

UltraSON™ – Making femto deployments ultra easy!

As a father of two kids, I am the happiest when they self organize their things without my intervention. Well, that might be a bit of a stretch when it comes to kids, but it’s actually a reality for unplanned, plug-and-play femtocells, thanks to Qualcomm’s UltraSON (Ultra Self Organizing Network).

The ins and outs of MIMO in HSPA+

With a few exceptions, more is always better — and antennas are no exception! Realizing this, HSPA+ evolution incorporates a slew of advanced multi-antenna techniques such as MIMO (Multiple Input Multiple Output), Beamforming/Transmit Diversity, and others. MIMO is one of the main components for enabling HSPA+’s famed, successively higher peak data rates – starting from 28 Mbps in Rel. 7 to 168 Mbps in Rel. 10, and even higher in Rel. 11 and beyond, also called HSPA+ Advanced.
