Agere Systems Introduces Industry's ATM Adaptation Layer System-on-Chip for 3G Wireless Applications

date: June 5, 2002

Agere Systems announced a system-on-a-chip (SoC) that enables wireless network operators and original equipment manufacturers (OEMs) to efficiently transmit higher-quality and greater volumes of voice, video and data over asynchronous transfer mode (ATM) networks.

ATM is the preferred broadband protocol in deploying 3G wireless infrastructure for its high and reliable level of multimedia applications support, scalability, multi-gigabit capacity and quality of service (QoS). Called SAR-2K, the new chip helps bring wireless voice, video and data services to a variety of new consumer devices such as personal digital assistants, Web-enabled cellular phones and other mobile Internet appliances in next-generation radio access networks and wireless base stations. With 10 million gates, it integrates the most hardware and software in a single chip of its kind compared to competitive products. The SAR2K also replaces up to five components while offering speed and performance enhancements that can save significant amounts of development time and lower system costs compared to other solutions.

The SAR-2K maintains high-speed ATM connections of multimedia traffic between base stations and radio access network controllers. "It provides complete functionality for delivering the ATM adaptation layer necessary for 3G wireless traffic, while minimizing power consumption and cutting time-to- market for our customers' new radio access network controller and base station designs," said Jaime Mitchell, product marketing manager with Agere Systems.
