19. INDUSTRY
Selected Use Cases

20. Infrastructure strain monitoring
25
Remote strain monitoring of aging infrastructures such as
bridges, roads or tunnels, to drastically reduce infrastructure
monitoring costs and facilitate maintenance and management
§ Easy to deploy (no wiring)
and long battery (5 years)
§ Infrastructure monitoring
cost reduced by up to 90%
(no more on-site inspection
imposed by regulation)
§ Prevention of aging
infrastructure accidents
§ Check remotely the
structure deformation via
PC and Smartphone app
ST-COMM system using up to 4
strain gauge sensors and cloud
application. It allows to detect
structure deformation and stress
before visible damages like cracks
occur. It can be used to measure
and detect deformation of various
structures (materials) including
concrete, mortar, metal, plastic,
wood, asphalt, glass, etc.
Much cheaper and more efficient
than conventional methods (e.g.
visual inspection or image
analysis combining drones and AI)

26. Anti jamming capability
for home alarm
32
Alarms are connected to central system using GSM. Thieves use
sometimes GSM jammers making it inoperative to burgle home.
§ Sigfox brings a clear
competitive advantage
towards Securitas Direct
competitor.
§ Ensure service continuity
§ Already in Spain, France,
Portugal!
This anti-jamming system does
not go through the GSM network,
which the most savvy burglars
manage without difficulty to
scramble with dedicated devices.
The network developed by Sigfox
is inviolable and thus becomes the
ultimate weapon to fight effectively
against alarm jammers.

61. Global network
Sigfox is offering a global network, not a
solution to build private networks
Roaming is included in the standard service
Devices will work the same all over the
network

62. Deployment model
All deployments aims to achieve a nationwide coverage
quickly
Low density of access points : metropolitan France is
covered with 2200 stations
Low cost of base stations + Small number = Low CAPEX &
Low OPEX = Low subscription costs

63. Densification
Micro base stations available for sale online (400€), to
extend coverage if needed (remote areas, deep indoor, ..)

64. Cloud

65. Get your data
View messages : Sigfox web platform
Get messages : REST API (pull)
Receive new messages : HTTP Callbacks
(push)

67. Callbacks
Each message received from your devices will be forwarded to
your application server(s)
Fully customizable HTTP requests
Used to send data back to the device as well
Easy integration with major Cloud solutions :
AWS, MS Azure, IBM, Samsung, SAP, theThings.io, Thingworx, …

68. Sigfox integrates with Azure IoT hub
natively
Sigfox <=> Microsoft cloud-to-cloud integration
Each message sent from Sigfox devices having
an Azure subscription is automatically forwarded
to Microsoft IoT hub
2-ways native connector at Sigfox
