Industry’s first single chip to integrate GPS, Bluetooth and FM technology
Addressing increasing consumer demand for GPS, Bluetooth wireless
technology and FM radio in mobile handsets, Texas Instruments
Incorporated (TI) announced its NaviLink 6.0 (NL5500) solution,
the industry’s first single chip that combines assisted global
positioning satellite (A-GPS), Bluetooth 2.1 and ultra low power
technologies, as well as FM receive/transmit capabilities. Built on
TI’s DRP™ single-chip technology at 65 nanometer (nm), the
highly-integrated and cost-effective solution enables manufacturers to
introduce sleek, affordable and high-performance handsets with GPS
capabilities to the large mid-tier market and drive increased usage of
popular GPS-based applications such as 3-D mapping, location-based
services and safety services. The mobile user experience is further
enhanced by enabling consumers to enjoy simultaneous activities such as
navigating, having a conversation using a Bluetooth headset, while also
transmitting an MP3 file to the car radio using the FM transmit
capability.
Market trend reports and forecasts predict strong and growing demand
for GPS, Bluetooth and FM in handsets. “We see a strong
correlation between the demand for including the combination of GPS and
Bluetooth functionality, with GPS attach rates reaching 30 percent and
Bluetooth penetration approaching 70 percent by 2011,” said
Patrick Connolly, senior GPS analyst at IMS Research.
“Accordingly, we believe that combo devices that integrate both
technologies will play a major part in the uptake of GPS in the
cellular market over the next four years – reducing cost, size
and power consumption, while also maintaining performance.”
Building upon TI’s proven expertise in delivering combo or
multiple-radio processors, NaviLink 6.0 is the third generation of the
company’s highly integrated single-chip GPS devices. This new
solution leverages TI’s Bluetooth and FM cores, which are already
embedded in the company’s BlueLink™ 7.0 Bluetooth, and
WiLink™ 6.0 mobile WiFi devices. NaviLink 6.0 reduces board space
by up to 40 percent, enabling the smallest possible phones and reduces
power consumption by up to 50 percent over previous TI solutions.
“NaviLink 6.0 enables TI’s customers to further enhance the
mobile user experience by bringing popular GPS functionality and mobile
connectivity to broader market segments,” said Remi El-Ouazzane,
vice president of TI’s Wireless Terminals Business Unit.
“With TI’s unparalleled ability to effectively and
efficiently combine multiple radios on a single die, the NaviLink 6.0
solution delivers an enhanced user experience in an affordable package
to meet our customers’ requirements.”
The NaviLink 6.0 solution also addresses the complex coexistence
challenge. TI’s hardware implementation and software algorithms
are optimized to ensure seamless coexistence between GPS, Bluetooth,
FM, WLAN and cellular functions. As more connectivity technologies are
integrated into cell phones, the more challenging it becomes to ensure
minimal interference between the various radios in these complex mobile
phone systems.
Another important customer concern is the time it takes the GPS system
to identify the starting position – called “time to first
fix” (TTFF) and the accuracy of that position. The NaviLink 6.0
solution includes enhanced patent pending algorithms to dramatically
reduce the TTFF by up to 80 percent over previous TI solutions.
Integrated “position optimizer” software also includes
support for navigation sensors, delivering superior accuracy in weak
satellite signal areas, such as urban centers and heavily wooded areas.
