1. INTRODUCTION
1.1 Product presentation
SIGFOX Access Station Mini is used for the densification network coverage and
customer on-demand coverage extension. With its compact form factor and low
energy consumption, it can be installed indoor or outdoor: on pole, on wall, etc.
The product is based on the carrier grade SBS-T Base Station platform with low
power consumption and high level of integration, comprising radio, baseband and
backhaul functionalities with Ethernet & Cellular connectivity.
It is available in two frequency variants targeting IoT applications worldwide:
•SMK-868 operates in the 865-870 MHz band.
•SMK-902 and SMK-902b operate in the 902-928 MHz band.
SIGFOX Access Station Mini can fit in any terrain from rural, suburban to city
locations and enable versatile installations at numerous sites ranging from indoors
wall mount and desktop to outdoors on pole or rooftop.
It has a broad operational temperature range and can be used in varied climatic
conditions including outdoor weather proof resistant (IP 65) configuration.
The installation of the base station can be easily completed by one installer
making deployment quick and easy.

1.2 Installation Overview
The Base Station should be used with the half-wave 2dBi antenna
provided.

2 INSTALLATION SITE RECOMMENDATIONS
SMK Access Station mini has been developed for indoor and outdoor operation. It
is certified including a 2dBi hinged half wave antenna that can be set straight or
swivelled at right angle
Note: For outdoor operation, the adjunction of sealing cover is mandatory.
Recommendations within this chapterare available for all the SMKoperating bands.
2.1 Antenna placement and near field clearance
Whatever the type of installation, SMK antenna shall be clear of massive
obstacles or metallic surface within 1m, since possibly altering operation.
When site placement constraints do not allow to respect antenna clearance,
nominal service may not be achieved.
•For wall mounting inside a building, the antenna can be swivelled at a 90°
angle, to mitigate shadowing.
•For indoor installation, the SMK shall not be used within a metallic closet or
within technical room with metallic door.
•For outdoor installation, SMK antenna shall be placed vertically.
2.2 Coexistence with other RF equipment
As any radio equipment, SMK access station mini must be installed with proper
decoupling precaution versus other radio transmitters. Should the quantified
decoupling recommendation listed below be infringed, SMK access station mini
would enter degraded operation, including and coverage reduction.
Decoupling protection is naturally expressed in dB, however for practical reasons,
this guide presents decoupling recommendation in terms of antenna alignment
and physical separation.
Systems co-location
In case of third party equipment co-location, SMK antenna shall be installed
vertically collinear to the existing antennas, with a clearance of 2m.
For indoor installation, the base station shall be installed at a minimum clearance
of 2 meters from any fixed radio device (e.g. DAS, or Wi-Fi access points).
Co-location of SMK access station mini on Telco site or with third party
SRD/ISM systems operating on the same band is forbidden.

7
2.3 Systems proximity
In case of third party equipment in close proximity, with line of sight visibility and
horizontal alignment, following physical separation is recommended:
System type
Minimum physical
separation
100KW Broadcast (FM or digital TV DBV-T)
1000 m
cellular macrocell (N x 2kW panel)
50 m
868-925 MHz SRD / ISM equipment
200 m
Wi-Fi
2 m
2.4 Admissible energy
SMK access station mini shall not be exposed to signals greater than -20dBm
from 0 to 821MHz and from 925MHz to 2.5GHz.
SMK access station mini shall not be exposed to integrated power greater than
1mW within +/- 200 MHz from its operating frequency.
Regardless the type of installation, the base station must be installed away from
obstacles possible altering the reception, and so that its RF connector must not
receive more than -20dBm signals from 0 to 821MHz and from 925MHz to
2.5GHz.

5 EARTHING
Earthing (or grounding) all components is important especially if the BS is installed
outside. The reasons are:
- Protection against lightning strikes;
- Evacuation of static electricity in the cables and equipment.
Make sure the earth connectors are placed on surfaces free of paint or corrosion
allowing the best electrical conduction.
Base station earth point is marked with following symbol:
To protect the station, it must be earthed with a G/Y 6mm2 wire (or AWG9).
First you need to unscrew the bolt M4 to insert a
grounding lug onto the HC screw M4x20 and the
over the 2 washers already in place. The correct
tightening torque is of 2.2 N.m. If needed, you
can bend the lug to ease the insertion of the wire.

6 BASE STATION INSTALLATION
For assembly instruction please see the relevant reference documents.
For desktop installation, make sure the surface is heat resistant.
6.1 Mast mount
The Base station can be mast mounted (pole diameter from 20 to 50mm) and
must be protected with sealing cover and optionally solar shade.
Instruction to mount the base station on a mast is provided with the mast
mounting set.
6.2 DIN Rail
The Base Station can be installed on a wall indoor or outdoor like a rooftop (with
sealing cover).

12
In wall mounting configuration indoor, the antenna can be bent at 45 or 90° away
from the wall to prevent losses.
Instruction for fixing the DIN rail (length 200mm) onto the wall and the base station
is provided with the Rail set.
7 BASE STATION WATERPROOFNESS
Connectors’ performances and lifetime strongly depend on waterproofness level.
The main purpose of ensuring waterproofness is to avoid the direct contact with
water and thus prevent connectors oxidation and protect against steam, salt and
dust.
The sealing cover ensures the waterproofness of the base station itself. The
gasket must be correctly positioned in the groove of the cover. Once the USB
dongle is connected to the station, the Ethernet and power cable and are passed
through the pipe of the cover and connected to the station, and bumpers are
placed around the cables. The cover must be screwed on the front panel of the
station.
