...to provide more responsive outdoor and indoor positioning capabilities for smartphone devices. With proven third-generation multi-constellation support and tight integration with sensor components and Broadcom's connectivity sub-system, the solution opens the door to innovative applications, such as indoor positioning and place-based mobile commerce. The architecture features a new Global Navigation Satellite System (GNSS) chip that significantly reduces time-to-first-fix (TTFF) for outdoor positioning applications, cutting the time smartphone users have to wait when first checking their position. The platform solution also uses data from inertial sensors, Wi-Fi access points (including those based on recently announced 5G WiFi) and future technologies such as Bluetooth beacons to enable ground breaking indoor positioning capabilities, such as "personal shopper" applications that can direct users to specific stores within shopping malls, and even specific shelves within those stores. In addition, platform integration with NFC enables smarter, more secure mobile payments, with users able to specify countries, cities or even stores where digital wallets can be used.
The Broadcom® BCM4752 GNSS chip provides the industry's most advanced multi-constellation support by simultaneously collecting data from four satellite constellations (GPS, GLONASS, QZSS and SBAS) and using the best received signals, resulting in faster searches and more accurate real-time navigation. Building on the success of previous GNSS chips, Broadcom's multi-constellation technology, coupled with advanced signal processing, provides faster positioning performance for improved user experience, especially in challenging urban environments where buildings and obstructions can dramatically impact accuracy and time-to-fix. The new chip and accompanying software benefit from tight integration with Broadcom's InConcert® wireless connectivity sub-system, featuring the most advanced and complete technology offering in the industry. By developing its various connectivity components to operate as a unified system, Broadcom can offer more expansive location features that extend beyond GNSS capabilities. The BCM4752 is production ready and shipping to early access partners.
