1 SIGFOX technology 
SIGFOX is the first and only operator of a cellular network fully dedicated to low throughput communication 
for  connected  objects.  With  an  extremely  cost  effective  and  very  low  energy  consuming  out-of-the-box 
connectivity offer, SIGFOX brings a revolution to the world of Internet of Things and M2M. The network, 
which already connects tens of thousands of objects, is being rolled out worldwide. 
2 Base station synoptic 
SIGFOX base stations operate on reception on a specific frequency bandwidth used by SIGFOX terminals. 
They are also able if necessary to transmit information to do single or multi-cast back to these terminals. 
The base stations include a complete system described in the following synoptic. 
Some elements are provided by the SIGFOX NETWORK OPERATOR (SNO) such as the antenna. 
The antenna characteristics depends on the operating frequency band and specific site constraints (gain, height, 
etc…). 
SIGFOX will provide the transceiver unit called SIGFOX Base Station transceiver (SBS-T) version V2 and 
the  corresponding  antenna  low  noise  switch/amplifier  (SBS-P).  This  component  integrates  a  low  noise 
amplifier in reception mode and a switch that bypasses this stage in transmission mode. 
This device characteristic depends also on operating frequency bands applicable in the region. 
SIGFOX Base Station transceiver (SBS-T) version V2 series are ultra wide range, high linearity transceivers 
units and feature first class performance radio and innovative software defined processing, for use in Ultra 
Narrow Band Machine-To-Machine wireless communication systems. 
Base  Station  transceiver (SBS-T) version V2 can have  a preset receiver frequency depending on the radio 
regulation applicable in the region. For instance, at 868.2MHz, targeting M2M application in European ISM 
bands or at 902 MHz for M2M application in US ISM bands. Other frequencies are of course possible. This 
choice is made by a specific software configuration. 
SIGFOX SBS-T series are indoor units with aluminum chassis, suitable for wall mount, rack mount or desktop 
installation.

4 Installation site recommendations 
This base station has been developed to be installed in indoor. 
It must be used with an LNA.  
It can be used also with a cavity filter. 
The datasheets of LNAs for 902-928MHz operation is in annex 1. 
The datasheets of LNAs for 868.13MHz operation is in annex 2. 
4.1  Cavity filter option 
The cavity filter use is optional in some countries. 
4.1.1 New Zealand 
In New Zealand this base station must be installed with the cavity filter described in annex 3 on the top 
of the LNA. 
4.2  Antenna  
This  Base  station  was  certified  with  an  Omnidirectional  Antenna  with  a  Gain  of  8dBi.  Only  an 
omnidirectional antenna with a gain of 8dBi or less can be used.

6 Warning statements 
6.1  FCC warning statement 
This device complies with Part 15 of the FCC Rules and with Industry Canada licence-exempt RSS standard(s). 
 Operation is subject to the following two conditions: 
(1) this device may not cause harmful interference, and  
(2) this device must accept any interference received, including interference that may cause 
undesired operation. 
 Changes or modifications made to this equipment not expressly approved by (manufacturer name) 
may void the FCC authorization to operate this equipment. 
 This equipment complies with FCC radiation exposure limits set forth for an uncontrolled 
environment. End users must follow the specific operating instructions for satisfying RF exposure 
compliance. This transmitter must not be co-located or operating in conjunction with any other 
antenna or transmitter. 
 This equipment should be installed and operated with minimum distance of 20 cm between the 
radiator and your body. 
 This equipment must be professionally installed. The installer is responsible for ensuring that the 
proper antenna is employed so that the limits in part 15 are not exceeded. 
 Only the antennas approved by SIGFOX must be used. The antennas may not be modified. The 
antenna must not be co-located or operating in conjunction with any other antenna or transmitter. No 
additional antenna must be used. 
NOTE: This equipment  has been tested and  found to  comply with the  limits for  a Class B digital device, 
pursuant to Part 15 of the FCC Rules.   These limits are designed  to provide  reasonable protection  against 
harmful  interference  in  a  residential  installation.    This  equipment  generates,  uses  and  can  radiate  radio 
frequency  energy  and,  if  not  installed  and  used  in  accordance  with  the  instructions,  may  cause  harmful 
interference to radio communications.  However, there is no guarantee that interference will not occur in a 
particular installation.  If this equipment does cause harmful interference to radio or television reception, which 
can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference 
by one or more of the following measures: 
 Reorient or relocate the receiving antenna. 
 Increase the separation between the equipment and receiver. 
 Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. 
 Consult the dealer or an experienced radio/TV technician for help. 
6.2  IC warning statement 
"Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a 
type and maximum (or lesser) gain approved for the transmitter by Industry Canada. 
To reduce potential radio interference to other users, the antenna type and its gain should be so 
chosen that the equivalent isotropic radiated power (e.i.r.p.) is not more than that necessary 
for successful communication. 
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to 
the following two conditions:  
(1) this device may not cause interference, and  
(2) this device must accept any interference, including interference that may cause undesired 
operation of the device."

This equipment should be installed and operated with minimum distance of 20 cm between the radiator and 
your body. 
Conformément à la règlementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une 
antenne d'un type et d'un gain maximal (ou inferieur) approuvé pour l'émetteur par Industrie Canada. 
Dans le but de réduire les risques de brouillage radioélectrique a l'intention des autres utilisateurs, il faut 
choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne 
dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. 
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de 
licence. L'exploitation est autorisée aux deux conditions suivantes : 
(1) l'appareil ne doit pas produire de brouillage, et  
(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage 
est susceptible d'en compromettre le fonctionnement 
Cet équipement est conforme aux limites d'exposition aux rayonnements IC établies pour un environnement 
non contrôlé. Cet équipement doit être installé et utilisé avec un minimum de 20 cm de distance entre la source 
de rayonnement et votre corps. 
7 Electrical connection 
The base station must be installed with a power point with the electrical protection according to the 
standards. 
In case the Base station is connected to mains by its electrical cable, the electrical plug must be easily 
reachable in order to remove the cable. 
In case the electrical plug is not easily reachable it is mandatory to have a circuit breaker system easily 
accessible for any technician in order to switch off completely the installation. 
8 Battery 
Attention: there is a risk of explosion if the battery is replaced by an incorrect type battery  
9 Earthing  
Earthing all components is extremely important. The reasons are:  
- Protection against lightning strikes; 
- Evacuation of static electricity in the cables and equipment.  
The coaxial cable must be connected to ground of the tower by at least two earthing kits (in line with the 
coaxial cable) at two locations on the tower at the top and bottom. 
Base station earth point is marked with following symbol:

9.1  Earthing the base station 
In order to protect the station, it must be earthed with a G/Y 6mm2 wire (or AWG9). 
First you need to insert a grower washer or a lock washer and a grounding lug into a hexagon socket screw 
M4x10. And then you must screw it into the hole provided for this purpose on the side of the station. The 
correct tightening torque is of 2.2 N.m. If needed, you can bend the lug to ease the insertion of the wire.
