Last week we published our cellular baseband market share estimates for 1H 2010. By our estimates, cellular baseband unit shipments grew 23 percent and revenues grew 15.5 percent from 1H 2009 to 1H 2010. The non-handset segment, which includes PC data cards, PNDs, netbooks, tablets wireless USB dongles and M2M, accounted for 12 percent of total baseband revenues in 1H 2010 and grew faster than the handset baseband market.

Here are some highlights of our cellular baseband market share estimates:

• Qualcomm continued its revenue share lead with 39.6 percent share in 1H 2010. Qualcomm ranked number one in CDMA and W-CDMA baseband markets. We believe much of the Qualcomm's growth came from smartphones and non-handsets in 1H 2010.

• MediaTek ranked number two in revenue share behind Qualcomm with 16.3 percent share in 1H 2010. Contrary to popular perception, MediaTek currently doesn't compete head-to-head with Qualcomm and only recently launched its first W-CDMA baseband. By our estimates MediaTek had less than 1 percent W-CDMA share in 1H 2010 but the company ranked number one in GSM/GPRS/EDGE (GGE) and TD-SCDMA baseband markets in revenue terms. MediaTek’s baseband shipments to grey handset OEMs showed signs of decline in 1H 2010 in the wake of government-led crackdowns in India and China.

• ST-Ericsson finally showed signs of recovery in 1H 2010 after a difficult 2009 with its improved and rationalized product line up for GGE, TD-SCDMA, W-CDMA and LTE markets. However, the company has to shift its focus to its stagnant W-CDMA market share to compete against Qualcomm and Infineon.

• Infineon continued to gain share in GGE and W-CDMA markets with the help of its top-tier handset OEM relationships. By our estimates Infineon is emerging as a strong competitor to Qualcomm in the non-handset market also with 9 percent unit shipment share in the non-handset segment of the W-CDMA market. Infineon is expected to improve its non-handset baseband share further once Intel completes its acquisition in 2011. Texas Instruments' exit from the baseband market creating opportunities for Infineon and Broadcom at Nokia.

• Broadcom's baseband revenue grew 245 percent in 1H 2010 compared to same period the year before thanks to its design-wins at Nokia and Samsung. By our estimates W-CDMA revenues accounted for 17 percent of Broadcom's total baseband revenues in 1H 2010 and the company continued to improve its product-mix.

• Spreadtrum, Marvell, Icera, and Via Telecom also made progress in 1H 2010. Renesas' baseband revenues were down slightly but the company is expected to emerge as strong player by 2012 with LTE chipset design-wins at Nokia.

Looking forward, we believe that the non-handset market and new radio technologies (HSPA+, LTE and TD-SCDMA) to create growth opportunities for baseband vendors.

Consolidation in the baseband market continued with Intel acquiring Infineon's wireless business on Monday for $1.4 billion. Infineon's takeover is the fourth high-profile announcement in the last two years. Previously NXP, Freescale and Texas Instruments announced their exits from the merchant baseband market. This signals that the entry barrier is now too high for new entrants and raises pressure on smaller players such as Marvell, Spreadtrum and Icera. Intel's acquisition of Infineon's wireless business leaves Qualcomm, MediaTek, ST-Ericsson, Intel, Broadcom and Renesas as long-term players in the cellular baseband market.

We analyzed this back in May when the original rumour of the Intel/Infineon wireless deal surfaced. Infineon's wireless business is definitely an attractive target for Intel as it gives immediate access to valuable IP and an established customer base. Infineon is a rising star in the W-CDMA baseband market and ranked number two in the W-CDMA baseband market behind Qualcomm (excluding Texas Instruments’ custom baseband business with Nokia). Infineon has so far focused on slim modems and has stayed away from developing ARM-based applications processors. So far Infineon’s niche strategy has paid off, but the time has come for the company to expand its portfolio by offering a wider range of processors to address smartphones, tablets and other connected consumer devices. Although 3G and smartphones are of most interest to Intel, the company is likely to keep Infineon’s 2G business as it provides scale which is crucial to play in the cellular baseband segment.

It will be another year or two before Intel's applications processors are smartphone-ready. Meanwhile, in the next 12 - 18 months Intel can bundle Infineon's 3G platform with all of its notebook and netbook chipsets and gain significant 3G share to undercut Qualcomm and ST-Ericsson's non-handset offerings. But both Qualcomm and ST-Ericsson appear to have a two year technology lead over Infineon in chipsets for HSPA+ and LTE; Infineon is expected to introduce its first HSPA+ chipset in 2011 and an LTE chipset in 2012. MediaTek’s grey handset chip business may come under pressure from Infineon in the future if Intel expands its field application engineering force in China. Likewise, Broadcom is expected to come under pressure from this deal but should survive with help from its other businesses such as connectivity and digital home. This acquisition will also likely affect stand-alone application processor vendors such as Texas Instruments and NVIDIA that currently lack their own 3G / 4G modems. But we believe that it will take another 4-5 years for Intel to integrate basebands into its Atom CPU, if at all.

Infineon's acquisition still doesn’t guarantee Intel's success in the wireless handset market and the company's ultimate success in this market hinges on how soon Intel can come up with power-efficient processors that can stand-up and compete against a host of ARM-based processor vendors. On a positive note, Intel appears to be moving ahead of its other chip competitors in the software area which positions it well against ARM-based processor vendors. The company’s strong software expertise could help it to gain some OEM mindshare. Intel’s uninspiring track record in the wireless market during the last decade suggests that the company has to execute flawlessly this time to make it successful and keep Infineon’s wireless business as independent as possible.
