Market drivers for location-based services (LBS)

Page 2

LBS is mass market

Smartphones all feature GPS to

enable consumer LBS

High volume and high growth

500K+ iOS apps

450K+ Android apps

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

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

Indoor positioning – PDR only

+

+

Start

Last GPS fix

Once GPS is lost indoors, the

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

50m

End

Indoor positioning – Wi-Fi only

Once GPS is lost indoors, the

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

SiRFusion positioning – Fusion of GNSS, PDR and Wi-Fi

Once GPS is lost indoors, the

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
