Global,
to be used everywhere
Low cost,
to address everything
Easy to use,
and adopted quickly

4. Backed by large corporations
Investors Partners & Customers

5. LPWA Market size

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. CONFIDENTIAL 7
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
BenefitsSolution

8. Home Alarm System
CONFIDENTIAL 8
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.
Challenge
BenefitsSolution
Alternative partners for this application

9. Package Pick-up
Service
CONFIDENTIAL 9
Allow customers to send packages from home.
▪ Improved effectiveness :
decrease the waiting line
at the Post Office
▪ Increase the customer
satisfaction
▪ Differentiation vs.
competitors (DHL,
Chronopost)
The smart button placed inside the
mailbox notifies the mailman that a
package has been placed in it and
should be picked up for delivery.
Challenge
BenefitsSolution

10. Gas cylinders tracking and
CO2 tanks monitoring
The first solution collects
accurate data from the
fleet of returnable
containers.
The second solution
monitors the level of
CO2 tanks.
Problem solved
Get some visibility on gas cylinders and
CO2 tanks inventories and supply chain
BenefitsSolutions
• Provide insights on the value
chain
• Real-time visibility on inventories
• Automate supply chain (refill)

15. RANDOM ACCESS
CONFIDENTIAL 15
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

16. CONFIDENTIAL 16
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

the signal to be

26. So.. Which one to choose ?
It all depends on the use case!
Most important:
• SDK?
• Other connectivity?
• Support?
• Price?
• Power Consumption?
• Availability?
• Size?

27. Antenna : THE most important
part
PLAN IT WHILE DOING YOUR PCB!
• Balance between design & perf
• Depends on the use case
• Target u0 (+14 dBm or +22 dBm)
• Hire an antenna guy if you need so
• https://build.sigfox.com/antennas
27

28. Antennas
• Lots of providers on shelves (Molex, Pulse, Linx..)
• Can do your own
• All depends what you have & need!
• Sens’it antenna: open source design
https://build.sigfox.com/antennas#antenna-design-example

29. Antennas ( small feedback)
Antenna Price Size Integration Perf Indoor?
External YES
Internal wire YES
Ceramics NO
PCB printed YES

30. Batteries
• Sigfox predictability: no signaling,
1 message = X uAh
• Different types of batteries = Different Use
Cases
Rechargeable device?
Size constraints?
Radio Zone has little impact on battery life
• Peak current while transmitting
20 to 50 mA in Europe, 130 to 250 mA in US
Coin cell: short lifetime
Can work with extra (super)-
capacitor circuit
Prefer multiple smaller
batteries over a big one

31. Batteries life example
• 10 msg (UL) + 1 DL / day
• 6 bytes
• Zone 4 Wisol module
• Idle + Sensor = 1 uA
Lithium , 2 Ah = 1140 days
Alkaline, 2 Ah = 3400 days
• 50 msg (UL) + 1 DL / day
• 0 bytes
• Zone 4 Wisol module
• Idle + Sensor = 1 uA
Lithium , 2 Ah = 618 days
Alkaline, 2 Ah = 1100 days

32. Radio zones
• RZ1: Europe, MEA
868 MHz, +14 dBm
• RZ2: North America, Brazil
902 MHz, +22 dBm
• RZ3: Japan, Korea
920 MHz, +14 dBm, LBT
• RZ4: South America
920 MHz, +22 dBm

33. Multi radio zones devices
• Hardware Single Zone
Different Hardware (modules)
Different module version but same pinout/PCB
• Hardware Multi Zones
Same Hardware, stay in the same zone
Set zone during production/firmware flashing
• Software Multi Zones: Monarch service
Same hardware, moving interzone
For specific worlwide asset tracking use cases
Require specific Sigfox firmware on module (more information coming soon)

34. Tools

35. Testing tools

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

54. 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

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.

63. Downlink Callback

64. 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)

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

68. How to request a downlink
Same AT command, with additional parameters
