Lantiq Brings HD Voice Quality to 2.4 GHz Cordless Home Phones

Lantiq has expanded its family of single-chip solutions for advanced cordless home telephony with a new 2.4 GHz COSIC WDCT device for DECT phones targeted at Asia-Pacific countries and emerging markets that use this unlicensed frequency range.


It supports wideband voice and low-rate data services (similar to European CAT-iq™ feature-set) to make the cordless phone a value-added component of a digital home. The device's wideband coding and transmission and advanced acoustic echo cancellation results in brilliant HD voice quality for conversation and recording, including full duplex hands free speaking with HD sound. It feautres adaptive collision detection and channel selection for co-existence with 2.4 GHz wireless LAN, and a high-signal-to-noise ratio (sensitivity approx. -98 dbm) reduces transmit power requirement and achieves better range performance than alternative devices.


All members of Lantiq's COSIC family integrate baseband controller, RF transceiver and power amplifier on single silicon chip, resulting in lowest system Bill of Material (BOM) cost, optimized manufacturing and logistics, smallest PCB footprint and low power consumption.
