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!

Qualcomm has lined up an arsenal of exhibits demonstrating our technology prowess. I would like to give a sneak peak at some of them, especially, the ones related to the 3G/4G technology evolutions being developed at our Corporate R&D facilities around the world.

The focus for us this year is a phenomenon that has piqued a lot of interest in the industry lately —HetNets or Heterogeneous Networks. HetNets are the networks with a mix of large macrocells and smallcells. As explained in my previous blogs, small cells bring a big leap in performance. But our point is — it’s not just adding small cells. Optimizations such as “Range Expansion” can increase the usefulness of these cells and make the performance leap substantially bigger. Our demos show this improvement both in HSPA+ Advanced and LTE Advanced technologies.

LTE Advanced

The first part of our live HSPA+ HetNets demo showcases the benefits of Range Expansion that can be realized in today’s networks through simple parameter optimizations, and when using existing dual-carrier devices.

The second part shows the performance improvement when Range Expansion is combined with a HSPA+ Advanced feature called MultiFlow.


The LTE Advanced demonstration shows another version of Range Expansion, achieved through adaptive resource partitioning and advanced receivers. To prove all this, we are using our own LTE Advanced, over-the-air test network in San Diego, CA, USA. If you visit the demo between 2-7PM (Barcelona time) you can even get into a live video conference with the test van in San Diego, and say “Hi” to our engineers, and remotely play with the network settings. How cool is that!

We are also partnering with Nokia Siemens Networks (NSN) for a joint demonstration showcasing the benefits of HSPA+ Advanced “MultiFlow.” MultiFlow enables users to connect to two cells on the same carrier, providing substantially improved data rates for users at the cell edge. It helps in offloading highly-loaded cells by utilizing the unused capacity from lightly-loaded neighbors. This demonstration uses NSN’s commercial Single RAN offering and Qualcomm’s prototype USB dongles.

Also on display are the commercial femtocell products from leading vendors based on Qualcomm’s FSM chipsets. These femtocells exemplify how FSMs enable vendors to build compact, yet powerful, femto solutions. More importantly, they come packed with Qualcomm’s state-of-the-art UltraSONTM interference and mobility management suite. Additionally, we are presenting a new concept of building out neighborhood networks using femtocells on dedicated spectrum.

To summarize, we are still doing the heavy-lifting (And I do mean literally — man, those shipping crates are heavy!) to bring these demos to the MWC, and convince you that HetNets are possible today. They substantially increase individual user data rates and increase the network capacity needed to efficiently carry your data. And going forward, they will evolve — to get even better at it.

Got to go now to pack our demo equipment and ship it to Barcelona, Hope to see you there at the Fira. Chao.
