US : InterDigital Communications Corporation (NASDAQ:IDCC), a leading architect, designer and provider of wireless technology and product platforms, is showcasing its innovative UMTS FDD HSDPA and Adaptive Interference Management(TM) (AIM) product solutions this week at CTIA Wireless 2005 (Booth 4821) in New Orleans, Louisiana.

InterDigital's HSDPA demonstration features an application of streaming video over an HSDPA enabled PC card and software that dynamically adapts to changing channel conditions. Compliant with the 3GPP Release 5 standard, the Company's HSDPA product is a cost-effective solution designed to integrate with existing FDD physical layer chips. InterDigital's coprocessor architecture supports peak data rates up to 14Mbps.

Offered as technology blocks for incorporation into FDD Release 99/Release 4 chips or as a separate coprocessor, InterDigital's HSDPA product features an advanced receiver design that delivers improved performance, data throughput and network capacity. The solution efficiently scales to all HSDPA data rates, and offers a rapid time-to-market upgrade to FDD HSDPA Release 5. The Company is targeting third quarter 2005 for availability of its HSDPA coprocessor ASIC.

In addition to the HSDPA coprocessor, InterDigital is developing a complete FDD Release 5 solution for Layers 1, 2 and 3, which is targeted for availability in the first half of 2006. InterDigital's HSDPA demonstration also will be featured in Anritsu's booth (#637) at the CTIA Wireless show.

Mark Lemmo, Senior Business Development Officer, stated, "The products we are showcasing this week at CTIA Wireless are high performance, cost-effective solutions that enable wireless equipment producers and operators to provide their customers with exciting new data-intensive and multimedia products and services. Our HSDPA and Adaptive Interference Management solutions substantially improve wireless device and network performance, increase capacity and coverage, reduce the effects of interference, and enable higher data throughput -- all of which enhance quality of service. We are committed to providing our customers with leading-edge solutions that enable them to rapidly deploy differentiated products and services, and reduce costs."

The Company is also showcasing its pioneering AIM solutions for WLAN devices and access points, including AIM ANTENNA(TM) and AIM PERFORMWARE(TM) products. InterDigital's AIM solutions are low cost, high performance products that reduce the effects of interference, enhance network capacity and coverage, extend battery life, deliver higher average data rates and enable equipment manufacturers and semiconductor suppliers to differentiate their WLAN product offerings.

InterDigital's AIM ANTENNA solution combines fully integrated patented beam steering software and antenna designs to deliver maximum performance to the antenna enabled subsystem in mobile terminals and WLAN devices including PC cards, USB sticks and dongles, and mobile devices. Using a high gain steerable beam, InterDigital's AIM ANTENNA products significantly enhance signal quality by allowing terminal devices to transmit and receive signals directionally, toward the desired signal and away from interference.

The AIM PERFORMWARE solution is an RF interference management middleware product that minimizes the impact of RF interference in WLAN networks and can be easily integrated into a Wi-Fi manufacturer's access point platform with minimal customization. Using patented RF measurement-based technologies, a WLAN access point enabled with AIM PERFORMWARE can dynamically monitor the radio environment and automatically optimize important system parameters such as channel and power. The result is optimum performance, predictable and continuous coverage, and improved customer satisfaction.
