CSR today announced it has successfully integrated GPS with
cellular measurements to create eGPS(R) (enhanced Global Positioning
System) technology capable of providing accurate position information
on demand in all environments. CSR will be demonstrating the benefits
of eGPS technology at Mobile World Congress (MWC 08) in Barcelona.
CSR's location technologies are now proven to provide significant
power and performance improvements necessary for embedding into a
mobile handset. CSR's first single-chip GPS with embedded Bluetooth
and FM radio technologies is back from the fab and proven working.
CSR's eGPS demonstrations take place at Mobile World Congress Hall 1,
stand 1E51 from 11 - 14 February 2008.

CSR's CEO, Joep van Beurden commented, "Along with last month's
announcement of the intention to form the EGPS Forum with Motorola,
our working silicon and demonstrations at Mobile World Congress are
all significant steps on CSR's roadmap towards adding high
performance, yet power-efficient eGPS to cellular phones at an
additional cost of less than $1." van Beurden continued, "Our patented
eGPS technologies are ready to change the market for location
technologies in mobile handsets."

CSR's GPS demonstrations at MWC 08 will show its technologies
providing real-time GPS navigation embedded in a mobile handset as
well as improving the responsiveness and availability of accurate
position information compared with assisted GPS (A-GPS) in a live
cellular network.

CSR's patented eGPS techniques augment traditional GPS or A-GPS
with cellular network measurements to provide a much improved user
experience. Universal availability of location information, increased
responsiveness and reduced power consumption make eGPS far more
appropriate for use in mobile handsets when compared with current GPS
technologies. eGPS works globally, providing far more accurate
position information than conventional cellular-based technologies and
allowing carriers to support the fine time aiding critical to GPS
performance in difficult environments without needing expensive
overhauls of unsynchronised GSM or W-CDMA network infrastructure.

In January, CSR and Motorola announced their intention to create
the EGPS Forum:

CSR's eGPS demonstrations show how its technology can be easily
embedded into a standard slimline handset and minimises power usage as
well as avoiding conflicts with other handset technologies. Using
off-the-shelf mapping software, CSR's handset demo shows highly
accurate turn-by-turn navigation driven by signal processing software
running entirely upon the embedded host applications processor. A
comparative demo against conventional A-GPS systems shows greatly
improved time to first fix (TTFF) in difficult environments and a
reliable fallback position based on cellular measurements when A-GPS
fails. CSR's Bluetooth silicon with embedded support for eGPS allows
satellite measurements to be maintained when the host processor is
powered down, providing position information on demand while
minimising power and resource loads. A typical eGPS push-to-fix will
be available in less than 4 seconds, accurate to within 10 metres and
require the equivalent power of less than 1 second of handset talk
time.

CSR has a long history of success in embedding radio technologies
in mobile handsets for customers such as Nokia, Motorola and Samsung.
In January 2007 CSR announced its acquisition of GPS specialists
NordNav Technologies AB and Cambridge Positioning Systems. By
combining its expertise with that of its acquisitions CSR has been
developing eGPS product offerings that support satellite navigation
and other location-based services.
