UWB and Wi-Fi as Mobile Sideload Interface

Driven by consumer desire to sideload mobile content and applications onto mobile phones, USB was employed in more handsets than all other interface standards combined in 2006, according to iSuppli Corp.

By the end of 2010 USB will still be the leading local interface, forecast to be included in 764 million of all the mobile handsets shipped that year.

"All the excitement and hype in the marketplace has been about Wi-Fi and Bluetooth integration in mobile handsets. However, as consumers endeavor to move both personally and professionally created contenton and off of their mobile handsets, the local interface selection of choice clearly will be USB," said Frank Dickson, principal analyst with iSuppli.

"Nonetheless, Bluetooth is gaining ground fast. By 2010, Bluetooth and USB will be available on nearly every handset, and WLAN and NFC will have established a significant market presence."

The increasing prevalence of these local interfaces on mobile handsets, and the mobile applications they enable, is spurring increased demand for mobile handset memory.

Applications such as digital imaging, video and audio streaming, music downloads and interactive gaming are imposing significant changes on mobile handset memory.

Shipments of flash memory add-in cards for mobile phones are expected to increase dramatically during the coming years, growing to 640 million units in 2010, up from 186 million units in 2005.

Much of this growth is being driven by mini and micro versions of the SD flash memory cards suited for mobile phones.

Security IP Market: The Platform Era Arrives

For years, security intellectual property (IP) existed in the semiconductor world as something of an afterthought; bolted on at the tail end of chip design cycles and treated as a compliance checkbox. That era is decisively over. According to the latest market study by ABI Research, the Security IP sector is entering a sharply accelerated growth phase, driven by a shift in how OEMs think about trust, compliance, and embedded protection. The message from the market is unambiguous: integrated, certification-ready security is no longer optional infrastructure; it is a competitive imperative. The explosion of connected devices across industrial, automotive, consumer, and data center environments has expanded attack surfaces. Security IP Market Development Meanwhile, regulatory frameworks worldwide are tightening, demanding demonstrable security assurance rather than self-attested claims. And looming on the horizon is the quantum computing threat, which is already forcing forward-thinking c...
