3/16/05 - Texas Instruments Incorporated (NYSE: TXN) introduced the WiLink
mobile Wireless LAN (mWLAN) platform, which includes single-chip solutions to
drive Voice over WLAN (VoWLAN) into mainstream mobile phones. With single- chip
solutions based on TI's innovative DRP technology, the WiLink mWLAN platform
underscores TI's leadership in enabling seamless wireless connectivity to mobile
devices. Comprised of hardware and software optimized for mobile phones, TI's
WiLink solution will provide consumers with on-the-go voice access over a WLAN
or cellular network using their mobile phone.
"VoWLAN is becoming the emerging driver of WLAN technology integration
into mobile phones and requires advanced technology for improved battery-life
and talk-times," said Marc Cetto, general manager of TI's Mobile
Connectivity Solutions Business. "As VoWLAN services become mainstream,
TI's WiLink mobile WLAN platform will allow manufacturers to deliver a lower
cost VoWLAN-enabled platform for consumer use. This becomes increasingly
important to make the 'one phone' or 'universal phone' concept a reality. We
expect consumers will soon be able to use only one phone for their mobile,
office and home phones."
Today, WLAN and VoWLAN capabilities have only been found in high-end mobile
phones primarily aimed at enterprise users. However, the WiLink solution
delivers the performance, small size and price-point required by OEMs to provide
cellular-WLAN phones and converged devices to consumers.
A complete hardware and software solution announced today, the WiLink 4.0
mWLAN platform, TI's fourth generation mWLAN solution, consists of two different
options to meet a variety of marketplace needs. Manufacturers can choose between
the TNETW1251 WiLink 4.0 802.11b/g single chip or the TNETW1253 WiLink 4.0
802.11a/b/g single chip depending on their product requirements. The platform
includes a robust software package, the WiLink 4.X Software Development Kit
(SDK) to deliver VoWLAN capabilities for mainstream mobile phones.
The WiLink 4.0 TNETW1251 and TNETW1253 single-chip solutions are the
industry's first WLAN products manufactured in a 90nm advanced RF-CMOS process
and leverage TI's DRP technology. As a result, both chips offer smaller size at
a lower cost and longer battery life than current solutions. The WiLink 4.0
platform also leverages TI's expertise in providing battery-saving low power
modes including TI's ELP(TM) technology.
"VoWLAN penetration in homes and businesses is expected to propel the
mobile WLAN market to new heights, offering consumers more choices in
connectivity," said Allen Nogee, principal analyst, of In-Stat. "Texas
Instruments has been a pioneer in the mobile WLAN space and is continuing that
tradition by leveraging its single-chip expertise and DRP technology to provide
their WiLink mobile WLAN solutions for cell phones. Mobile WLAN has been a
natural fit and success for TI and has led to many customer design-wins with
major OEMs over the past three years."
The WiLink 4.0 mWLAN solution leverages TI's expertise gained from the
company's three previous generations of mobile WLAN solutions being shipped in
over 20 wireless terminals products today. The single chips join the company's
already sophisticated and integrated single-chip roadmap, including Bluetooth(R)
wireless technology and a single-chip solution for mobile phones. TI's
integrated wireless technology roadmap also includes a single-chip solution for
digital TV for mobile phones, as well as future single-chip solutions for GPS,
UMTS and other air interfaces, paving the way for further integration with the
cellular modem and TI's OMAP(TM) processors.
Through TI's expertise in mobile connectivity, the WiLink 4.0 platform was
designed to provide coexistence and interoperability throughout the mobile
phone. This includes enhancing TI's WLAN-Bluetooth coexistence capabilities
without sacrificing call quality or performance, including sharing common
resources such as the antenna.
TI's WiLink SDK 4.X includes a "Thick MAC" architecture which
off-loads some of the host processing functions to the single chips which
enables WLAN support on low-end CPU host processors commonly found in low-end
mobile phones. The WiLink 4.0 solution supports CCx3.0 and CCx4.0, Unlicensed
Mobile Access (UMA) and the emerging 3GPP IMS and SIP standards. The solution
also includes enhancements to provide WLAN handoff between access points (APs)
within a WLAN network. The 802.11b/g and 802.11a/b/g solutions support IEEE and
industry standards for security and quality of service including 802.11i,
802.11d, 802.11k, WPA2.0, and WME/WSM. The 802.11a/b/g solution also includes
support for 802.11h and 802.11j for 802.11a operation.
The WiLink 4.0 TNETW1251 and TNETW1253 single chips include the MAC, baseband
and RF transceiver functions in one 6x6mm BGA package which enables the most
competitive board area design. Since the two chips are pin-for-pin compatible,
TI provides OEMs with the flexibility to populate either 802.11a/b/g or
802.11b/g in the same board design which allows manufacturing time adjustments
to meet specific market demands or easy migration to 802.11a/b/g products from
802.11b/g designs.
The WiLink 4.0 mobile WLAN 802.11b/g and 802/11a/b/g solutions are expected
to sample in 3Q 2005. Products integrating TI's WiLink 4.0 platform are expected
to be released to market in 2Q 2006.
