2. What is Sigfox?

3. Sigfox: Global LPWA network
Low power,
to provide autonomy
Global,
to be used everywhere
Low cost,
to address everything
Easy to use,
and adopted quickly

5. CONFIDENTIAL 5
Parking space management
• Improve parking policies
• Obtain turnover information in real
time
• Guide drivers more efficiently
• Have greater control over special
permit spaces
• Save resources through fast
implementation
• Decrease costs through easy
maintenance
• Generate additional revenue
• Decrease CO2 emissions
Fastprk is an intelligent Parking
Management System that
allows cities and operators to
manage parking resources more
efficiently and parking
operators to generate additional
revenue.
Fastprk offers information about
parking availability to the drivers
within blue and green spaces,
and also on loading, taxis and
disabled parking bays
Problem solved
Optimize parking spaces in the city

6. Sensolus offers an end-to-
end tracking solution.
It notifies Airbus about its
assets’ trips and give insights
on supply chain optimization.
The device embeds an
internal memory to record
data when outside of
coverage.
Problem solved
Track spare parts between the headquarters
and the sites of its suppliers
BenefitsSolution
▪ Cross country tracking
without high roaming fees
▪ Real-time visibility on the
asset during transportation
▪ Automation of the supply
chain
Industrial asset management
GPS + BLE tracker for indoor
and outdoor geolocation

7. Home Alarm System
CONFIDENTIAL 7
Alarms are traditionally connected through GSM to central system and
burglar intrusion can be facilitated by GSM jammers. There is a need
for effective backup connectivity to ensure more robust alarm
transmissions.
▪ Robustness of solution is a
commercial differentiator
▪ Continuity of service
▪ Soft deployment via over the
air update - no HW swap. No
user impact
▪ Network available to handle
millions of devices
Sigfox has upgraded Securitas
Direct’s alarm systems to provide a
back-up connectivity in case
jamming is detected.
The upgrade was possible over the
air as a Sub-GHz chip was already
inside.

8. Stolen Car Recovery
CONFIDENTIAL 8
Locate and recover stolen assets through a small and
discrete GPS tracking device.
▪ Peace of mind that assets
can be tracked or
recovered
▪ Complete solution with
added services
▪ No jamming
Small sensor : 2/3 of the size of a
cigarette pack
Connected with the Police 24
hours / 7 days
Autonomy : 3 to 5 years of use
Internal antennas (UHF and GPS)
Tracking through GPS and UHF
Geo-localization active in

12. RANDOM ACCESS
CONFIDENTIAL 12
Unsynchronized transmission between the network and the device
The device transfers a small amount of energy on a random frequency with no protocol overhead
(frequency hopping)
SIGFOX Base stations permanently listen to the spectrum and interpret received UNB signals
The same frame is sent 3 times enabling time and frequency diversity

Frame2 @F2

13. CONFIDENTIAL 13
Anti-jamming capabilities due to UNB intrinsic ruggedness coupled with spatial diversity of the base stations (+20dB)
HIGH RESILIENCE TO INTERFERERS
robust to operate in the public ism band
For the same technical reasons as above, UNB is extremely robust in an environment with other spread spectrum signals.
However, Spread spectrum networks are affected by UNB signals. Ultra Narrow Band is therefore the best choice to
operate in the public ISM band
8 dB needed for
the signal to be
received

31. Hello World

32. Hello World
https://github.com/nicolsc/mkrfox-hello-world
#include <SigFox.h>
void setup() {
SigFox.begin();
short valA = 7700;
float valB = 654.32;
SigFox.beginPacket();
SigFox.write(valA);
//SigFox.write(valB);
SigFox.endPacket();
}
void loop(){}

33. Message received ?
http://backend.sigfox.com (check your e-mails to get
credentials)
Navigate to the devices menu in the top bar
Click on the ID of your device
Enter the messages menu from the left navigation column

34. Check device messages

35. Callback setup
Device Type menu
Click on your device type name
Enter the Callbacks menu
Select new default callback

40. Callback status
In the Devices > Messages panel, you have a indicator of the
callback status (an arrow)
Black : in progress
Green : Callback OK
Red : Callback KO (at least one of the callbacks failed)
Click the arrow to display details.

42. Frame parsing

43. Sigfox payload display feature
Using a « simple » grammar, you can ask Sigfox to parse
your incoming data
This is done at the device type level

46. Parsing the Hello World sample
Modify the sketch to send 3 values in a same message
short valA = 7700;
short valB = 128;
float valC = 654.32;
SigFox.beginPacket();
SigFox.write(valA);
SigFox.write(valB);
SigFox.write(valC);
SigFox.endPacket();

47. Set a custom grammer
valA & valB are shorts : 16 bytes
valC is a 32 bytes float
valA::uint:16:little-endian
valB::uint:16:little-endian
valC::float:32:little-endian

48. Downlink Callback

49. How does it work?
Downlink flag included in Sigfox message
20 sec after first frame transmission, the module wakes up
and waits for downlink response (25 sec window)

50. Downlink Callback setup
Automatic callback: Device Type > Informations > Edit
Set Downlink mode to DIRECT
Enter an 8 bytes value

53. Sample code
Simple change
SigFox.endPacket(); to
SigFox.endPacket(true);
This will request a response from the network

54. Handle the response
https://github.com/nicolsc/mkrfox-downlink
void loop(){
while (SigFox.available()) {
Serial.print("0x");
Serial.println(SigFox.read(), HEX);
}
}

55. Geolocation

56. Geoloc callback
Simply create a SERVICE > GEOLOC callback,
and receive latitude + longitude + accuracy

57. Geolocation Callback
Create a new
Service > Geoloc
callback
Use following URL
to center the map:
https://maps.googleapis.com/map
s/api/staticmap?center={lat},{lng}
&zoom=13&scale=1&size=600x300
&maptype=roadmap&format=png
&visual_refresh=true

58. Event monitoring

59. Monitor break in sequence number
New Event: Device > Event Configuration > New
Select Event Type « Out of message sequence »
Select « EMAIL » as channel and enter your email address
and email content

60. Monitor break in sequence number
Remove the antenna to simulate a coverage issue
