Single-chip wireless engine for VoIP base-stations

23 July 2008 Telecoms, Datacoms, Wireless, IoT

Infineon has developed what it says is the world's first single-chip CAT-iq/DECT wireless engine for base-stations, dubbed COSIC (cordless single chip)-Modem. The COSIC-Modem integrates the baseband processor, transceiver and power amplifier in a monolithic CMOS 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 high definition sound quality simultaneously 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 optimised system design for CAT-iq cordless base-stations by delegating the performance of the DECT software stack to the CPE SoC and focusing on the basic wireless communication tasks itself. 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. The COSIC-Modem also supports adjustable radio levels for emission control.
