Quick overview about Sigfox technology. Flyer format.

1. Radio technology
key points
Ultra narrow band
Sigfox uses 200 kHz of the publicly available and unlicensed bands to exchange radio messages over the air (868 to 869 MhZ and 902
to 928 MHz depending on regions). Sigfox uses Ultra Narrow Band (UNB) technology combined with DBPSK and GFSK modulation.
Each message is 100 Hz wide and transferred at 100 or 600 bits per second data rate depending on the region.
Random access to the radio frequency resource
The transmission is unsynchronized between the devices and the network. They broadcast each message 3 times on 3 different
frequencies (frequency hopping). The base stations monitor the spectrum and look for UNB signals to demodulate.
Small messages
Sigfox has tailored a lightweight protocol to handle small messages. An uplink message has a maximum 12-bytes payload and a
downlink of 8 bytes. For a 12 bytes data payload, a Sigfox frame will use 26 bytes in total.
About Sigfox
Sigfox is the world’s leading provider of
connectivity for the Internet of Things
(IoT). The company has built a global
network to connect billions of devices
to the Internet while consuming as little
energy as possible, as simply as possible.
Sigfox’s unique approach to device-to-
cloud communications addresses the
three greatest barriers to global IoT
adoption: cost, energy consumption, and
global scalability. With millions of objects
connected and a rapidly growing partner
ecosystem, Sigfox empowers companies
to move their business model towards
more digital services. Founded in 2010 by
Ludovic Le Moan and Christophe Fourtet,
the company is headquartered in Labège
near Toulouse, France’s “IoT Valley”.
Sigfox also has offices in Paris, Madrid,
Munich, Boston, San Francisco, Dubai and
Singapore.

Short technical presentation

2. Very long range
Low bit rate and simple radio modulation enable a 163.3 dB
budget link leading to long-range communications.
High network capacity
The small footprint of UNB enables more simultaneous signals
within the operation band and the Sigfox protocol cuts down the
radio frames size. These two qualities lead to a high capacity of
the SIGFOX network.
High resilience to interferers
UNB intrinsic ruggedness coupled with spatial diversity of the
base stations offer great anti-jamming capabilities. UNB is
extremely robust in an environment with other spread spectrum
signals. UNB is the best choice to operate on the public ISM band.
High quality of service
The objects are not attached to a specific base station. They
broadcast their messages which are received by any base
station in the range (3 in average). There is no need for message
acknowledgement. Spatial diversity coupled with the time and
frequency diversity of the radio frames repetitions lead to high
quality of service of the Sigfox network.

Low energy
The Sigfox radio protocol reduces the
radio frame size and no synchronization
with the network is required. Combining
a low power emission level and short
emission enables maximum autonomy of
objects.
Low cost
Benefit from widely available electronic
components, low battery utilization, low
solution deployment and integration
costs, as well as our simple network
infrastructure with long range high
capacities.
Simple
Removing the need to configure
connections and enabling standard based
device to cloud integration, means that
Sigfox is easier to use for everyone.
Complementary
Sigfox is complementary to Bluetooth,
GSM 2G/3G/4G and Wifi. By combining
other connectivity solutions with Sigfox,
business cases and user exprience are
drastically improved.
Global
Connecting globally is easier than ever.
Partners subscribe to one contract for
a worldwide network. And since our
network functions in the same way
globally, no matter the country, you can
have a single device running anywhere in
the world.
