Infineon returns to MWC: 'We never left'

Infineon Technologies makes a comeback at the 2015 Mobile World Congress. The last time it came to the Mobile World Congress as an exhibitor back in February, 2010. Its aim was to roll out a 3G slim-modem platform integrating its famed GOLD baseband processor and RF transceiver.

But since 2011, when it sold its wireless business to Intel, Infineon's name, along with its almost legendary baseband and RF technologies, has faded into the memory of the mobile world.

Infineon, however, has never left the mobile world, the company indicated. The company has issued this claim even though some of its own people thought Infineon had called it quits.

But never mind all that, because Infineon is back in Barcelona.

Five years are a long time, not just in the chip industry, but in the mobile business in particular. So, what changed?

First, the Mobile World Congress is no longer a show about mobile handsets. Today, it's all about billions of connected devices, the network infrastructure technologies enabling them, and the much-needed security that protects data transmission and transactions in networks and at end nodes.

Infineon executives said the Munich-based company has a lot to offer at Mobile World, with its focus on connectivity (RF in the network infrastructure), sensing (pressure sensors for smartphones), security (secure mobile payment technology embedded in handsets and tablets) and the energy efficiency it can bring to connected devices that need power.

For example, the high temperature-resistant pressure sensors Infineon originally developed for its automotive customers to monitor tire pressure in cars are now tailored to consumer handsets, and they are pitched as an answer to much needed indoor navigation applications.

The company's RF power group has been supplying power amplifiers in base stations, ranging from macro to micro and pico cells. It never left the mobile industry.

To support heterogeneous cellular network infrastructure, a technology has to connect different types of cells. Instead of running optical fibre cables between them, Infineon offers wireless solutions by using the mm-Wave radar technology for wireless backhaul communication of point-to-point base stations' connectivity.

The company's security chips originally designed for identification and banking cards are in demand for enabling secure transactions for Google Pay or Apple Pay on smartphones.
