Joint News Release by Infineon Technologies and Global Locate

Munich / Germany and San Jose / Calif. – October 12, 2004 – Infineon Technologies AG (FSE/NYSE: IFX) and Global Locate today announced that they are jointly developing the industry’s highest performing, single-chip Assisted Global Positioning System (A-GPS) receiver for mobile telephones, smart phones and PDAs. The new Hammerhead™ chip incorporates radio frequency and baseband GPS functionality enabling emergency assistance and location-based services for mobile phones. The chip includes Global Locate’s IndoorGPS® technology that assures operation in deep urban canyons, in moving vehicles and even indoors. Global Locate is contributing its knowledge in baseband design, signal processing, A-GPS software and system level know-how, Infineon its expertise in radio frequency design, system integration, process technology and manufacturing. Both companies will jointly market the Hammerhead chip.

The Hammerhead A-GPS chip from Infineon and Global Locate will be able to detect a GPS signal that is 1,000 times weaker than the normal “open sky” signal outdoors. All aspects of the design have been optimized for mobile handsets. The chip consumes very little power, has extremely robust performance and at 7mm on 7mm is no larger than a key on the dialling pad of a mobile phone.

“Once designed into a mobile handset, this state-of-the-art single chip will make it very easy for a user to find the nearest gas station, the nearest hospital, or the nearest restaurant,” said Dominik Bilo, Chief Marketing Officer at Infineon’s Secure Mobile Solutions business group. “It will enable mobile users calling emergency telephone codes, such as 911 in US or 112 in Europe, to provide emergency services with very accurate location information, both from indoors and outdoors.”

In the United States, A-GPS-enabled mobile telephones are in demand due to a U.S. Federal Communications Commission mandate, E911, which requires all wireless service providers to upgrade their infrastructure to enable accurate tracking of emergency calls placed from mobile telephones by the end of 2005. In Japan, all third-generation mobile telephones sold after April 2007 require A-GPS functionality to support emergency services as well.

“In 2008, we expect more than 730 million mobile phones to be sold worldwide,” said Bilo. “By then, greater than one in four mobile handsets will be equipped with GPS functionality.”

How GPS works

The Global Positioning System is a satellite navigation system that allows a user, i. e. of a mobile phone, to pinpoint his exact position on the globe at any time, at any location, in any weather. More than 28 GPS satellites orbit the Earth and broadcast signals that can be detected by anyone with a GPS receiver. By using the receiver to measure the distances from a number of satellites simultaneously users can precisely determine their location at any point on Earth in a process akin to triangulation. GPS receivers are widely used in cars, trucks, ships and airplanes all over the globe.

Location-based services using GPS have been difficult to implement in mobile telephones because the weak signals are difficult to detect indoors, inside moving vehicles and other environments where mobile phones are commonly used. Even outdoors, a mobile phone’s traditional GPS receiver can take several minutes to receive satellite navigation data and to compute an accurate position. The technique of assisted GPS uses the cellular connection to transmit the remotely collected satellite navigation data from the basestation to the mobile phone allowing the user to pinpoint his exact position in only seconds. A-GPS and the unique signal processing of the Hammerhead chip result in unprecedented speed and sensitivity.

“Assisted GPS is the superior technology for revenue generating location-based services,” said Donald Fuchs, Executive Vice President of Business Development for Global Locate. “Users will rely on it for emergency services, finding friends or family; gaming or simple point-to-point navigation. Location-based services will provide value to users and an additional revenue stream to mobile network operators.”

Technical details of the Hammerhead chip

The Hammerhead chip, also marketed under the name PMB2520, for the first time integrates all functions required of an A-GPS receiver into a single chip, and supports mobile station-assisted (MS-A), mobile station-based (MS-B), autonomous and enhanced tracking modes. Best in class indoor performance is a result of its sensitivity to -161 dBm (abbreviation for decibel milliwatts) allowing the detection of GPS signals which are 1,000 times weaker than open sky signals outdoors. At 7mm x 7mm the single-chip receiver has a very small footprint for easy integration into small electronic devices. The unique architecture has been optimized for mobile devices and does not require additional RAM or ROM memory capacity resulting in a low bill-of-material parts count. It is based on the Infineon 0.13 micron RF-CMOS process technology. The Hammerhead will be offered in a standard VQFN-48 green package, a Very thin Quad Flatpack Non-leaded standard chip package with 48 pins.

Infineon and Global Locate expect to have samples available in the first quarter of 2005. The price for the Hammerhead chip will be 6.50 Euros in quantities of ten thousand units.

The Hammerhead product is a continuation of the multi-faceted partnership between Global Locate and Infineon. Infineon is the foundry for the successful GL-LN-22 RF Tuner designed and marketed by Global Locate in 2003. In February 2004, Infineon and Global Locate collaborated on adding IndoorGPS functionality to Infineon’s MP-1 multi-media reference design supporting the UMTS, EDGE and GPRS cellular standards.
