are gearing up to meet increasing consumer demand for converged devices,
or smart phones, market research firm IDC said Monday. The market for
stand-alone PDAs (personal digital assistants) has been dropping steadily
for several quarters, as consumers and businesses hold off on purchasing
anything other than essential technology items, IDC said. In 2003,
worldwide handheld shipments will decline 8.4 percent to 11.35 million
units. However, shipments of converged devices, which combine voice and
data communications, will increase to about 13 million units by the end of
2003, IDC said. Converged devices are either cell phones with data
capabilities, or data-centric PDAs with voice as an application, said Alex
Slawsby, an analyst with IDC.Read the full story on:
InfoWorldAirgo Promises Breakthrough in Mobile-Call QualityAirgo
Networks Inc., a secretive Silicon Valley start-up composed of a superteam
of wireless pioneers, this week said it will reveal plans for what
analysts say could offer a revolution in wireless transmission quality.
Airgo will begin offering sample versions of its short-range radio antenna
chips to equipment makers. The chips promise to boost the speed, range and
reliability of wireless devices indoors and between nearby buildings.
Airgo is offering its digital signal chips for use in so-called 802.11
short-range radios, which became the industrys hottest trend when Intel
Corp. began building wireless connections into notebook computers in
March. Read the full story on:
ComputerworldDotcast Unveils Chip That Delivers Data over Analog TV
Dotcast Inc. has opened the hood on a chip that uses existing analog TV
signals to ferry digital data to the home. Dotcast (Kent, Wash.) said it
has designed a digital signal processor that harnesses NTSC signals to
deliver digital content a rate of one to three Mbits per second.
Eventually the company expects to push that rate up to 4.5-Mbits per sec.
The ReX chip takes a different approach from other "datacasting"
techniques such as the use of DTV signals or unused portions analog TV
spectrum. Instead, the ReX chip places data on top of existing video and
audio signals. For this to work, the data spectrum has to be prefiltered
and the subcarrier carefully spaced to avoid impairing picture quality.
Signals can be received by households with a TV stations so-called
contour A sphere with a bit-error rate of 10-8. There are 1.67 million
contour A households in Los Angeles, for example, according to Simovich.

EE TimesBroadcom Links Bluetooth Device to Qualcomm CDMA
ChipsetsBroadcom is looking to increase the penetration of its
Bluetooth technology into the CDMA handset market with the release of the
Blutonium BCM2004, a single-chip CMOS Bluetooth radio chip that links up
with Qualcomms popular mobile station modem baseband chipsets. Compliant
with the Bluetooth 1.1 and 1.2 specs, the BCM2004 is an integrated
transceiver that incorporates a fractional-N frequency generator to
synthesize all standard reference frequencies required for implementing a
Bluetooth radio in mobile phone designs. Read the full story on:

Samsung Electronics Co. Ltd., the worlds No. 3 maker of wireless
telephones, on Monday said it landed an agreement to provide telephone
handsets to AT&T Wireless Services Inc., extending its push into the high end of the U.S. wireless market. The first product to be marketed will be
the v206 model, a clam-shell shaped phone with a full-color screen and a
built-in camera. The handset costs about $400. AT&T Wireless customers can
use the new phone to access high-speed data services, imaging, text
messaging and wireless Web services.
