Intel's Surprise Mobile Acquisition

Late last month, Intel quietly acquired Tempe, Arizona-based Fujitsu Semiconductor Wireless.  To my knowledge, no news announcement has been made, but this is a very important move for Intel as Fujitsu Wireless had developed probably the most advanced multimode LTE RF Transceiver available in the open market.  The operation traces its lineage through Freescale Semiconductor, the previous owner, and earlier Motorola Semiconductor.  Intel has acquired a truly seasoned technical staff, now probably their most seasoned U.S.-based wireless talent.

Why no news release?  I suspect that Intel was not eager to embarrass its former-Infineon staff in Germany, which has been the major player in 2G/3G RF Transceivers and has shipped a multimode LTE RF Transceiver (but not an LTE modem) in selected Motorola Droid smartphones.   In my February 2012 profile of the Fujitsu operation, I stated "[the operation] still remains as probably the best stand-alone RF team in the world." 

The new Intel operation's latest RF Transceiver product includes advanced features like Antenna Tuning and Envelope Tracking. With its internal DSP that also supports smart antennas, device support for any application processor is accommodated (even an X86…wink, wink). The team has been busy working on the next gen LTE-Advanced solution preparing for Carrier Aggregation designs.  It now appears that Intel's wireless geographic center of gravity has shifted a bit.

Did Nokia's Selection of Windows Doom Renesas Mobile?

You may recall that in mid-2010 Renesas Electronics Corp. acquired Nokia's wireless modem operation and added the group to its new subsidiary, Renesas Mobile Corporation.  Renesas Electronics had licensed the Nokia modem since 2009 and the two companies had been working together to develop an industry-leading HSPA+/LTE platform.

Unfortunately for Renesas Mobile, Nokia decided to throw its future into the arms of Microsoft's Windows Mobile O/S.  But the only way Nokia could bring Win Mobile to market quickly was to employ Qualcomm's readily-available modem and application processor platform (Snapdragon).  It appears that move cost Renesas Mobile its biggest modem customer.  Moreover, Renesas Mobile was never able to find another big customer for its own worthy multimode LTE modem that I mentioned in my last newsletter.

Renesas Electronics tried to sell the Mobile subsidiary, but there are few companies who are big enough to afford absorbing the substantial wireless design staff that would go with such an acquisition. After all, the major smartphone companies already have committed modem chip relationships: Apple, HTC and Nokia with QualcommSamsung with Samsung Semiconductor, Intel with its own newly-minted modem operation, etc.  There are probably a dozen Chinese companies who would love to have the Renesas Mobile technology, but most aren't big enough to absorb the Renesas headcount.  That leaves licensing of the IP as probably the remaining viable option for Renesas.

Comments on the ST-Ericsson Split 

Now that Ericsson owns the modem properties and STMicroelectronics owns the application processor product line of the former merged company, I'll make some quick observations:

1) Ericsson's modem business has reverted to what used to be called the EMP division (Ericsson Mobile Platforms). EMP was a leading supplier of complete 3G baseband/RF platforms to the handset industry before the ST-Ericsson merger, rivaling what was then Infineon Technologies.

Ericsson is still shipping stand-alone TD-SCDMA modems in China (11% market share in 2012), GSM/EDGE modems (9% market share in 2012) and WCDMA/HSPA+ modems (2% share in 2012).  However, Ericsson now has a very worthy multimode LTE modem and RF transceiver product (The latest "Thor" part of the STE "NovaThor" combined product).  However, during 2012, ST-Ericsson's Thor modems (at least the HSPA versions) were designed into smartphones from HTC, Samsung, Motorola, Panasonic and Sharp.

Ericsson's best near-term prospects will be to provide LTE/TD-SCDMA modem/RF transceivers that can appeal to China Mobile's many prospective smartphone suppliers. Those smartphone suppliers can get application processors on their own (or maybe buy them from STM).  Better yet, Ericsson should consider adding LTE to the NovaThor 9240integrated dual-core com-processor approach for China's TD-SDCMA market (licensing IP for the AP from STM?).

2) STMicroelectronics (STM) now retains the "Nova" part of the ambitious STE combined product, namely the ARM-based application processor product line.  Although the prospects of getting an STM application processor in a major smartphone are dim (who doesn't already have one?), at least STM can employ the device in other multimedia devices, including the automotive market, where they have better prospects.  Or, they can partner with Ericsson for the China Mobile market, mentioned above.

Shameless Plug:

Our annual detailed report of cellular handsets, tablets and the chips that enable them is in "Comprehensive Cellphone & Tablet Chip Markets'13." At 641 pages, the report is the most extensive available...anywhere. Starting with analysis of the 2012 "core" chips that define a cellular terminal (baseband, apps processor, power management, and RF) followed by the most extensive analysis of "peripheral" chips (like Bluetooth, Wi-Fi, Mobile TV, NFC, Touch Controllers, Image Sensors, GPS, FM/AM, HDMI, MEMS, etc.). This study explores the dynamics of all these devices andprofiles the chip providers and market shares for each of them.

We have been told that there is no other cellular chip market study available that has the breadth or depth of coverage of this one. Shipped as PDF only (with enterprise-wide license), discounts are available to those who purchased our study of "core" cellular chip markets earlier this year. Check the website to get an idea of the full extent of this valuable study and all of the components and companies covered: Details are at www.fwdconcepts.com/Cellchip13

As always, I encourage your feedback.
