Sigfox Coverage Measurement Methodology with the CheckFox
What is unique about Sigfox
★ Connectionless network
★ Probabilistic network based on 3 so called diversities
★ Managed network
★ Coverage built up to certain standards worldwide
★ Operating at the edge of possible with little space of error
Sigfox is an IoT network with the
highest worldwide coverage, being
present in more than 60 countries
worldwide.with already more than
21 countries/territories covered

What are coverage maps
All the models of coverage are calculated as outdoor coverage at 1,5m height above ground.Indoor and
deep indoor coverage is mathematically calculated as places requiring 20 dBm resp. 30 dBm margins -
their signal attenuation.
Outdoor - 0 dBm
1,5 m above ground, 1 m from any wall
Indoor - 20 dBm
generally defined as rooms above ground with windows.
Deep indoor - 30 dBm
defined as either underground with window or above ground without window.
Please be aware that modern office buildings with metallic facades and windows act as Faraday cages
and may require densification.
Importance of redundancy
What influences coverage predictions
Sigfox operators work additionally with Population density that is super critical in
calculating coverage commitments and Population covered but has NO influence on
➔ Are unique for each Sigfox operator and evolved in time
➔ Some make sense others don't
➔ The only common long term commitment seems to be 85 percent indoor
➔ What is mostly missing and is critical for tracking use cases is coverage of
highways, transit railway line, ports and international crossing
Plus super deep redundant indoor coverage of airports
What coverage you should get and ask for worldwide
➔ All major cities, ports, airports full deep indoor redundant.
➔ all towns and villages above 4000 people should have full indoor coverage
➔ towns of 10 000 up this coverage should be redundant
➔ all international highways, ports, border crossings should have indoor coverage
➔ over 90 percent of the country should have outdoor coverage
Is Sigfox coverage usable for my project ? 1/3
Do a complete Discovery and project definition first.
What, at what cost, at what reliability, where you want to achieve….
Business case MUST be the driving force NOT the technology.
Sigfox is targeting only 7 percent of the market.
For some of the use cases LoRa, NB-IoT, GSM, Bluetooth or WiFi can be far better
Is Sigfox coverage usable for my project ? 2/3
Is it one country ?
Submit all your locations to Sigfox Operator and they will return the level of
coverage. After that it is your mastery of negotiation. If not content with
coverage try to talk to Sigfox country manager. Keep in mind that it need to
make sense for all sides, so don't force the Operator to cover a village of 200
people in valley. Use your own micro Access station or repeater.
You can also offer your locations for Sigfox operator installations so it can be a
win win situation for all sides.
Is Sigfox coverage usable for my project ? 3/3
Multiple countries and not millions of devices.
Here the situation is more complicated. Sigfox should enforce proper coverage and
help in projects but it works case by case.
The rules of rent/sales for Micro Base Stations differ country by country, the attitude
of Sigfox operators differ country by country…
Be persistent, patient. Raise the issue not only with Sigfox operators but with
Country managers and if not successful escalate to regional or superregional Sigfox
How to measure Sigfox coverage
A. Does the predicted coverage match the actual coverage?
B. Will a reference device work at the installation spot?
C. What is the attenuation between reference measurement and final destination?
D. What is the reliability of the reception over time?
E. Does my HW device work as well as the reference device?
→ Always take photos
→ Always follow some methodology
Role of devices and its placement
Device emission classes Are they relevant ?
