Aperto Networks Chooses Fujitsu System-on-Chip for Its WiMAX Systems; Aperto Deploys Fujitsu Silicon for Base Stations, Business-Grade Subscriber Units.

LAS VEGAS -- Aperto Networks, a leading WiMAX multiservice systems provider, and Fujitsu Microelectronics America, Inc. (FMA), a leading provider of robust wireline and wireless solutions that boost next-generation communications networks in North America, today announced the results of their collaboration to test and integrate the Fujitsu MB87M3400 System-on-Chip (SoC) into Aperto's WiMAX systems development. Aperto has selected Fujitsu's SoC as the standard silicon for its PacketWave(R) base station systems and high-end series of business-grade customer premises equipment.

"We have tremendous confidence in Fujitsu's WiMAX silicon technology," stated Aperto CEO Reza Ahy. "Our team has worked with Fujitsu, its SoC emulation platform and reference design for many months, and with engineering samples since the first quarter of 2005. These have fulfilled all critical performance aspects needed for WiMAX certification of our systems and tight integration with the Aperto Media Access Control and patented ServiceQTM (Quality of Service) and OptimaLinkTM (link optimization) features.

"The Fujitsu WiMAX SoC's performance, availability and economics address our market requirements, and carriers are extremely pleased with Aperto's base station systems, which incorporate this technology," he continued. "The accelerated availability of the SoC is critical for our milestones, and multiple carrier field trials have been planned with our WiMAX systems using the Fujitsu chip."

Aperto and Fujitsu have moved quickly on pre-certification testing of all system functionalities, and are well on-track for the WiMAX ForumTM July 2005 early-stage Plugfest and tests at the WiMAX Forum certification lab CETECOM in Malaga, Spain.

"The Fujitsu WiMAX SoC architecture is highly synergistic with Aperto Networks' outstanding systems advantages in Quality of Service, with the ability to deliver multiple service flows simultaneously," stated Keith Horn, senior vice president of marketing and sales for Fujitsu Microelectronics America. "Our collaboration has validated this performance advantage, as well as the benefits of Fujitsu's footprint, processing power and power optimization, extended reach in NLOS environments and superior operation in full-duplex mode. These aspects are mission-critical to Aperto's success in the broadband wireless market, and they will help to preserve and extend Aperto's leadership in IP-rich systems functionality."

Aperto Networks will join the Fujitsu WiMAX SoC press conference at Broadband Wireless World Forum on April 21, 2005. The event will take place in the Genoa Room in Caesar's Palace, from 12:45 to 1:45pm. The two companies will demonstrate the integration of their technologies featuring simultaneous Internet access and video streaming at the Aperto booth (#211) and Fujitsu booth (#204).
