SiRF Technology Holdings, Inc., a leading supplier of GPS semiconductor and software solutions, today announced its flagship SiRFstarIII(TM) architecture, representing a significant increase in GPS performance, and enhancing the user experience for location based services (LBS (Location-Based Services) See mobile positioning. ). With its rapid time-to-first-fix and high sensitivity, the SiRFstarIII architecture is designed to meet the rigorous demands of wireless and handheld LBS applications, and provides superior location performance, both indoors and out, for 2G, 2.5G, 3G asynchronous Refers to events that are not synchronized, or coordinated, in time. The following are considered asynchronous operations. The interval between transmitting A and B is not the same as between B and C. The ability to initiate a transmission at either end.  networks.

SiRFstarIII will be on display with a variety of other new SiRF offerings (see press release entitled, SiRF Breaks Key Barriers to GPS-enable Mobile Wireless Devices) at the 3GSM World Congress in Cannes, France, Feb. 23 - 26, in Hall 4, Booth K17.

The SiRFstarIII architecture packs a performance punch, achieving time-to-first-fix of one second for aided starts in outdoor GSM environments and acquiring signals down to -159 dBm. This makes real-time navigation practical, including in many indoor environments, through urban canyons, and under dense foliage. Unlike the lengthy sequential search A search for data that compares each item in a list or each record in a file, one after the other. Contrast with direct search and indexed search.  process of traditional GPS architectures, the SiRFstarIII architecture, with the equivalent of more than 200,000 correlators, enables fast and deep GPS signal search capabilities, resulting in significant improvement over today's architectures that contain a few hundred to a few thousand correlators.

"Cell phones now dazzle consumers with built-in cameras, PDA (Personal Digital Assistant) A handheld computer for managing contacts, appointments and tasks. It typically includes a name and address database, calendar, to-do list and note taker, which are the functions in a personal information manager (see PIM).  functionality and color screens. We built the SiRFstarIII architecture from the ground up to deliver the performance necessary to provide fast LBS experience to the users of these devices," said Kanwar Chadha, founder and vice president of marketing for SiRF. "We believe SiRFStarIII sets a high standard for consumer GPS performance, ushering in Noun 1. ushering in - the introduction of something new; "it signalled the ushering in of a new era"

SiRFstarIII is supported by SiRFLoc multimode technology (see today's press release entitled, SiRF Multimode Location Server Makes LBS Smarter), SiRF's patented location solution that allows networks to move beyond basic "find and locate" applications to support a wide range of LBS such as navigation, without excessive network bandwidth requirements Bandwidth requirements (communications)

The channel bandwidths needed to transmit various types of signals, using various processing schemes. Every signal observed in practice can be expressed as a sum (discrete or over a frequency continuum) of sinusoidal

The SiRFLoc client software is designed to enable SiRFstarIII to determine position with aiding from GSM, WCDMA (Wideband CDMA) A 3G high-speed digital data service provided by cellular carriers that use the TDMA or GSM technology worldwide, including AT&T (formerly Cingular) and T-Mobile in the U.S. , CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. , iDEN and PDC (1) (Primary Domain Controller) A Windows NT/2000 service that manages security for its local domain. Every domain has one PDC, which contains a database of usernames, passwords and permissions.  networks -- or completely autonomously -- using multiple dynamically configurable modes. By employing the mode that provides an accurate location with the appropriate level of network aiding for any given situation, SiRFLoc's multimode location technology is designed to allow carriers to offer a wide range of location-based services with minimum network loading. All SiRFLoc-enabled systems share the same client interface, enabling customers to build handsets with any SiRF product and use the same system software.

"Motorola's iDEN Subscriber Group has been in the forefront of developing GPS enabled phones through our relationship with SiRF," said Jaime A. Borras, corporate vice president of Technical Staff, Motorola iDEN Subscribers Group. "GPS is now an integral part of our platform, and we expect the SiRFstarIII architecture to significantly improve the user experience in a range of new and exciting location-based applications and services."

The first chip-set based on the SiRFstarIII architecture consists of a highly integrated baseband IC and an RF IC that together are designed to deliver a complete location engine in a very small form factor -- ideal for devices with limited onboard processing power. One of the most compact GPS solutions on the market, it is nonetheless packed with lots of functionality. Based on a 0.13 micron CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss."

It is found in almost every electronic product from handheld devices to mainframes.  process, the SiRFstarIII baseband chip -- with its powerful GPS signal processor, on-chip memory, and a 50 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock.

Packaged in a 100-pin BGA (Ball Grid Array) A popular surface mount chip package that uses a grid of solder balls as its connectors. Available in plastic and ceramic varieties, BGA is noted for its compact size, high lead count and low inductance, which allows lower voltages to be used.  package measuring just 8 by 8 millimeters, the baseband chip also incorporates 4 megabits of flash memory to support both SiRFLoc (see below) and user application programs.

, and can support multiple reference frequencies to reduce costs.

In addition to the chipset, SiRFstarIII is also available in IP form for integration into high volume wireless chip-set platforms. The highly modular design of both the SiRFstarIII core IP and controlling software makes it easier than ever before to adapt these components.
