Single-chip CAT-iq Wireless Engine Designed for VoIP Basestations

(Product News, 14 Feb 2008)

Infineon Technologies has released what is said to be the world's first single chip CAT-iq/DECT wireless engine for basestations. Dubbed COSIC (cordless single chip)-Modem, the device integrates the baseband processor, transceiver and power amplifier in a monolithic CMOS single chip for high quality cordless IP telephony. In combination with Infineon's broadband CPE (customer premises equipment) SoCs (system-on-chips) Danube for ADSL2/ 2+, Twinpass for Ethernet and VINAX-VE for VDSL2, the COSIC-Modem handles up to six handsets in HD (high definition) sound quality at the same time and offers access to data applications as described in the CAT-iq roadmap.

With backward compatibility to DECT/DECT 6.0, the COSIC-Modem enables an optimized system design for CAT-iq cordless basestations by delegating the performing of the DECT software stack to the CPE SoC and focuses on the basic wireless communication tasks itself. This task partitioning eliminates the external memory required for the CAT-iq part in a base station and reduces at least 40 percent of the CAT-iq subsystem BOM (Bill of Material). Furthermore, as all applications are directly implemented on the memory of CPE SoCs', flexible resource management and remote feature update are achieved by this architecture for CPE vendors and service providers of both voice and data applications. COSIC-Modem especially supports adjustable radio levels for emission control.
