GeoFencing, GeoTargeting, GeoPositioning, Tracking…

“Trigger geofences based on events like

- entering, dwelling, or leaving a place

- time of day

- crossing a speed threshold

- entering a city, state or country

- after traveling a given distance

- after a particular change in altitude ”

From Innovation to Disruption – Accelerating the IoT Market

Partner Innovation Program with real

industrial design Targets

(Cost , Quality, Time-to-Market efficiency)

Thanks to Leading Silicon Vendors willing

to accelerate the IoT LPWAN Market

Sagemcom will

circulate (VERY

SOON) this

New Generation

Tracker as a

Catalyst for

Asset

Management/Lo

gistics, and

Child/Elderly

care.

MAIN Target:

Disrupt the

Market!

GPS information, machine learning (1/2)

Fingerprinting usually requires an initial ‘Offline’ phase, where calibration is

done for building an initial Radio Map (RSS, TOA, TDOA…).

Then, Machine Learning Algorithms can be used to classify/detect identical

patterns, and thus identify the Positions.

Ultimately, Online matching can also be used to adapt/enhance the initial

dataset/database.

GPS information, machine learning (2/2)

Supervised Learning

(Calibration phase needed)

1) K-Nearest Neighbor (k-NN)

2) Decision Tree (DT)

3) Neural Networks (NN)

4) Support Vector Machines

(SVM)

5) Bayesian inference

802.11 channels @2.4GHz – 14 channels

For sake of battery consumption, an Adapted

Scanning Policy, taking into account Radio

environment (e.g. Channel Popularity [1,6,11]) is

likely to improve the battery life. This could be

adapted by Application Layer.

Passive Vs Active Sniffing

Only 10% additional captured packets via Active sniffing

In our case, the IoT Device is only using Passing Sniffing,

for sake of battery consumption.

WiFi sniffing principle is applicable to any database, similar to Google API. Once Location of AP is

stored, together with their MAC address (Id), then RSSI algorithm can be applied.

Finally….

Sagemcom is deeply committed to make IoT LPWAN Asset

Management/Tracking a Business reality.

LoRaWAN™ via its inherited Time stamping capabilities from

CSS, together with Very Low Power & High Range

takes a definitely a Key Disruptive position in that Market.

Combining with other IoT Technologies such as GPS Offload,

WiFi scanning and BLE secures a strong Leader’s Position.

This is a joint Optimization Problem from the Device towards

Cloud Processing/Data Analytics & Anchors positions

Databases, via Gateways.
