Market drivers for location-based services (LBS) LBS is mass market  Smartphones all feature GPS to enable consumer LBS  High volume and high growth  500K+ iOS apps 2011 2012 2013  450K+ Android apps (MU) Smartphones 508 740 910 Source: CSR Estimates 2012 LBS is a daily experience  LBS used for search, maps, navigation, check-in, fitness, tracking, etc. But... LBS is currently not Indoors  Consumers expect functionality anywhere anytime  Consumers are indoors a very high percentage of the time Page 2

SiRFstarV™ – the next generation location platformSiRFstarV™ architecture and SiRFusion™ hybrid positioning system CSR Positioning Center Multisat GNSS MEMS Gateway SiRFstarV SiRFusion SiRFstarV Wireless Sniffer Pedestrian Dead (Wi-Fi, GSM, …) Reckoning Taking mobile location to the next frontiers

Competitive positioning CSR solution: zero install, zero survey and globally scalable  Announced indoor solution Nov ‘11  No new infrastructure required – relies on existing Wi-Fi transmitters  Can use new infrastructure when available including Bluetooth SMART  Users and building owners do not have to locate APs  System automatically learns from normal use  Demonstrated in various target environments  Shopping malls, train stations, convention centers, hotels, museums  San Francisco, Las Vegas, Barcelona, Seoul, Beijing, New York, Tokyo, Cambridge, Taipei Other solutions  Some solutions require Bluetooth SMART beacon infrastructure or other supplemental infrastructure  Requires investment by building owner  Some require survey work to position beacons  One solution requires round trip proprietary Wi-Fi measurements  Non-standards approach limits compatibility and coverage Page 7

Indoor positioning – PDR only Start  Once GPS is lost indoors, the + Last GPS fix PDR is used to keep track of position  The MEMS sensors drift and the error accumulates at a growth rate of 10% of distance travelled  Soon the position track is not representative of the actual path  The uncertainty illustrated by the size of the ellipses makes most indoor use cases impractical + End 50m

Indoor positioning – Wi-Fi only Start  Once GPS is lost indoors, the + Last GPS fix locations of Wi-Fi access + points are used to determine approximate position once every 20s  The uncertainty illustrated by + the size of the ellipses makes most indoor use cases + impractical  Once outdoors, a more accurate GPS position is obtained and the uncertainty shrinks + + + End 50m Page 9

SiRFusion positioning – Fusion of GNSS, PDR and Wi-Fi Start  Once GPS is lost indoors, the Last GPS fix MEMS sensor output is used for dead reckoning as the user moves  The error grows about 10% of distance traveled, so in 50m, the error grows only 5m  Wi-Fi positioning keeps the error from growing too large  The better accuracy allows the Wi-Fi access point locations to be determined more precisely End 50m Page 10

SiRFusion test – Tokyo Station  Lower level at Tokyo station  Google indoor maps for each level  Environment has no GNSS signal, lots of magnetic anomaly sources (tracks, elevators, escalators), and many people causing signal variations  Red flags mark the route walked  Blue dots mark the SiRFusion position Starting point determined using Wi-Fi only Page 14

SummaryEmerging indoor ecosystem New and existing applications need indoor positioning Navteq/Micello/Google/Microsoft indoor maps Google indoor advertisingSiRFstarV with SiRFusion Can be deployed worldwide using existing infrastructure No surveying required Target accuracy: within 10m 50% of the time Initial products in development Today’s demo features: SiRFusion brings positioning indoors!
