SAN JOSE, Calif. -- Atmel(R) Corporation (NASDAQ:ATML) , a global leader in the development and fabrication of advanced semiconductor solutions, and IPWireless announced today that they have collaborated, along with an Original Equipment Manufactures (OEM), to develop a UMTS TDD mobile handset. The mobile handset will allow UMTS TDD network operators to offer carrier-grade mobile voice over IP (VoIP) services, in addition to existing broadband and other packet based services, on their converged networks. IPWireless and Atmel have already completed the first successful transmission of a call from a mobile VoIP handset over UMTS TDD, an important milestone in the development of commercial UMTS TDD handsets.

UMTS TDD, the 3GPP standard optimized for high-speed data, is ideal for carrier-grade voice applications with its high capacity, low latency, and low power requirements. IPWireless's latest UMTS TDD software supports both dedicated and shared channels, enabling operators to deliver circuit-switched quality while enjoying packet-based system economic benefits. Operators can leverage existing network infrastructure to add VoIP over UMTS TDD services in a highly efficient, reliable, and economic manner, thereby increasing revenue while augmenting subscriber services. With a UMTS TDD VoIP handset, subscribers will experience the same quality of voice service they expect from traditional mobile phones. In addition, the handset's USB port allows users to connect it to computers or other devices and use it as a very high-speed broadband modem.

The UMTS TDD VoIP handset will use Atmel's highly integrated AT76C902 VoIP system-on-a-chip as the main processor, with the IPWireless TDD Module performing the UMTS TDD modem functions. The AT76C902, running the VoIP protocol software, voice compression and decompression, also provides the phones application functions for control of the keypad, LCD, speaker and user interface. The OEM will provide the plastics, LCD displays and keypads from existing handset models. UMTS TDD handsets prototypes will be ready by the end of 2004 with commercial availability of phones expected mid-2005.

"We are pleased to partner with Atmel to develop a mobile handset that will allow UMTS TDD operators to offer their subscribers the best in voice and broadband services while creating an additional revenue stream," said Chris Gilbert, chief executive officer, IPWireless. "Atmel's reputation in the industry is unparalleled, and we believe that their contributions to the UMTS TDD mobile handset ensure that the device will exceed operator and subscriber expectations."
