Application Examples
■ Personal Navigation: Never get lost again in foreign cities. Your mobile phone is
leading the way to your destination, whether you start indoors or outdoors. Avoid
being delayed in traffic jams by utilizing real-time traffic information.
■ Location-based Services: Finding the way to points of interest simplifies your life.
Take the short way to restaurants in your neighborhood, the nearest gas station or
metro station. Use your LBS application indoors to start planning your trip before
you get in your car.
■ Emergency Assistance: A-GPS-enabled mobile telephones are in demand to allow
accurate tracking of emergency calls placed from mobile telephones by the end of
2005. Hammerhead II will enable mobile users calling emergency telephone codes
to provide emergency services with very accurate location information, both from
indoors and outdoors.
■ Friend-Finder and Child-Safety: Meeting with friends and family is now an easy
task by sharing your personal location. Keep an eye on the current position of your
children and keep them away from dangerous places.

Advantages
Hammerhead II is based on Global Locate
IP and state-of-the-art Infineon RFCMOS
IP and process technology. This ground
breaking chip is the key for enabling
location-based services such as
emergency assistance and personal
navigation in deep urban canyons,
in moving vehicles, and indoors.
Hammerhead II uses the proven host-based
architecture pioneered by GL as the best
fit for mobile devices as proven in mass
market 2.5 G and 3 G devices shipping
now. GL host-based architecture leverages
some of the resources already existing
in the mobile device without imposing a
big CPU load (~ 3 – 6 MIPS) or any real
time requirements. Hammerhead II uses
standard serial communication interfaces
with speeds as low as 38,400 bps.
Global Locate’s Host-based architecture
yields the lowest system cost solution
as well as the smallest footprint without
compromising performance.
