Philips Electronics took the wraps off a complete Unlicensed Mobile Access (UMA) reference design for converged mobile handsets at the CTIA Wireless show Monday (March 14) and said it is working with Alcatel on interoperability tests between UMA handsets based on the Nexperia reference design and the French group's Spatial Atrium server/softswitch.

The client software for the reference design comes from one of the pioneers in fixed-mobile convergence technology, Kineto Wireless. The two companies sealed a long term collaboration deal last month at the 3GSM exhibition.

The companies say the UMA reference design "will create a blueprint for a mobile phone that accesses GSM and GPRS mobile services through traditional cellular networks to automatically switch over to WLAN access points."

The reference design incorporates what Philips says is the industry's lowest-power 802.11g WLAN system-in-a-package (SiP) for connections to WLAN access points. The 802.11g device also debuted at CTIA Wireless.

Combining the low-power 802.11g technology and Kineto's UMA switching technology with the Nexperia 6120 range of cellular solutions would make it easy for people to take advantage of advanced phone services, said Get-Jan Kaat, senior vice president, Business Unit Mobile Communications, Philips Semiconductors.

The WLAN SiP, already sampling, is a pin- and software-compatible with Philips' 802.11b, and is available separately.

Separately, Philips announced that it is incorporating the CryptoCell device security protocols into its Nexperia cellular multimedia baseband chips.

CryptoCell is becoming one of the most commonly used embedded security options for mobile devices and flash based storage. In addition to providing device security, the CryptoCell technology also improves power consumption.
