Lantiq launches phone chips; offers HD voice quality to 2.4 GHz cordless home phones

Lantiq, a supplier of broadband access and home networking technologies,
announced the expansion of its single-chip solutions for cordless home

The new COSIC WDCT, a 2.4 GHz version of the company’s DECT solution,
brings features such as wideband voice and low-rate data services to cordless
handsets targeted at Asia-Pacific countries and emerging markets that use this
unlicensed frequency range.

“With this addition to the COSIC product family, our customers can
field a complete range of cordless voice products based on a common platform
that offers unsurpassed performance and audio quality,” said Rainer
Spielberg, vice president of marketing for Lantiq.

“In-home cordless plays an important role in the voice and data
service customer experience. With features such as wideband voice and low-rate
data applications added to handsets, manufacturers can deliver products that
clearly stand-out from the ‘dumb’ phones in common use today,” Spielberg
