Broadcom Adds 3G to its Wireless Mix

Eyeing more placement for its chips in mobile phones, Broadcom spins Zyray Wireless' chip line into fold.

Looking to provide 3G for mobile phones, Broadcom agreed to buy Zyray Wireless for $96 million in stock.

Zyray makes co-processors that facilitate Wideband Code Division Multiple Access (WCDMA), a high-speed 3G wireless technology with the capacity to offer higher data speeds than CDMA for wireless phones. Broadcom will integrate the San Diego, Calif., company's SPINNERchip line, whose chips connect to EDGE/GPRS/GSM baseband processors via a standard memory interface.

SPINNERchip, which is currently being integrated into several handset designs, aims to help device manufacturers bring 3G phones to market more rapidly, something that industry analysts predicted would happen several years ago. But while 3G is fairly advanced in Asia-Pacific and Europe, the technology has yet to catch on in the United States.

Broadcom, an Irvine, Calif.-based chipmaker that competes with Agere Systems, Applied Micro Circuits Corp. and Marvell Technology Group, hopes to help change that with the Zyray purchase.

The company said in a statement it believes pairing SPINNERchip technology with its single-chip EDGE/GPRS/GSM and GPRS/GSM baseband processors will propel WCDMA multi-mode phones in the near term and "provide the potential for future solutions with enhanced integration."

WCDMA is so desirable to mobile phone makers and cellular carriers because it provides high-speed mobile connectivity with data rates of up to 384 kilobits per second. This higher bit rate makes possible applications for video telephony and messaging, rich media, interactive gaming, improved Web browsing and GPRS services.

This is crucial because many industry experts believe cellular phones will soon emerge as a personal communications hub for users. They will be able to play games, chat, browse the Web, watch streaming video and download music. This makes 3G highly lucrative for cellular carriers, which rely on bumping up the average revenue per user to make profits.

According to a recent Deutsche Bank Securities report, the worldwide WCDMA market is expected to approach 200 million units by 2008, representing more than one-fourth of the total handset sales.

"We see significant activity in the WCDMA handset space, and having Zyray's products and technologies in-house gives us the flexibility of offering our customers the ability to manufacture both low-cost EDGE phones, as well as higher functionality WCDMA handsets," said Robert Rango, group vice president of Broadcom's Mobile & Wireless Group, in a statement.

Broadcom will also tuck in next-generation technology from Zyray, including High Speed Downlink Packet Access (HSDPA) for integration into its next-generation family of devices. HSDPA is the next step in the cellular evolutionary path after WCDMA and is expected to provide data rates of up to 10 megabits per second.

Zyray is also developing Multi-In, Multi-Out (MIMO) transceiver technology that can vastly improve the performance of WCDMA and HSDPA. MIMO provides radio links with multiple antennas on the transmitter and receiver to improve wireless connectivity.

Broadcom, which expects the merger to close in its third fiscal quarter, has made a number of purchases in the past year to pad its chip lines. Most recently, the vendor acquired data-compression chipmaker San Video in April.

But Broadcom has been on a storage asset kick of sorts. Since buying bankrupt Gadzoox Networks last year, the company has acquired controller maker RAIDCore, as well as storage patents from Cirrus Logic.
