1. Product presentation
Sigfox Access Stations operate on a specific frequency bandwidth used by
sigfox devices. They perform mainly receiving operations (uplink), but are also
able to transmit information by doing downlink operations upon device request
The Access Stations Micro include a complete system described in the network
overview below.
Sigfox Access Station Micro 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.
Sigfox Access Station Micro system has a pre-set receiver frequency depending
on the radio regulation applicable in the region. This choice is made by a specific
software configuration.

4. Installation site recommendation
Access Station Micro has been developed for indoor and outdoor operation.
Note: For outdoor operation, the adjunction of sealing cover is mandatory to
insure waterproofness (see §4.4).
4.1. Equipment
For temporary location, the base station is perfectly stable sitting on a table, a
desk or a shelf.
For a more permanent installation, we recommend wall or pole fixation
A drill/screwdriver may be required if the station is to be installed on a wall.
4.2. Coexistence with another RF equipment
As any radio equipment, Access station micro should be installed with proper
decoupling precaution versus other radio transmitters. Should the quantified
decoupling recommendation listed below be infringed, the access station micro
would enter degraded operation, including coverage reduction.
Decoupling protection is usually expressed in dB, however for practical reasons,
this guide presents decoupling recommendation in terms of physical separation.

Minimum physical separation

100
m 1000m
1m
Co-location of access station micro on Telco site or with third party
SRD/ISM systems operating on the same band is forbidden.
Regardless the type of installation, the base station must be installed away from
obstacles possibly altering the reception, and so that it must not receive more
than -20dBm signals from 0 to 821MHz and from 925MHz to 2.5GHz.
General recommendation for outdoor installation would be to not place the
Access Station Micro in direct line of sight of broadcasting equipment or cellular
station.
For indoor installation, place the station in a different room as other RF
equipment, when possible install the station on a different floor.
Use of cell phones in direct vicinity of the Access Station Micro will not affect
neither its range, nor its quality of service.
In case of third party equipment in close proximity, with line of sight visibility and
horizontal alignment, following physical separation is recommended:
System type
100KW Broadcast (FM or digital TV DBV-T) 1000m
Cellular macrocell (N x 2kW panel) 100m
Cellular pico station 2m
3000m
300m
N/A
Wi-Fi 1m
4.3. Site selection
Radio performance will depend on site configuration. Whatever the type of
installation, the station should be clear of massive obstacles or metallic surface
within 1m, since possibly altering operation.
Indoor:
If the station is to cover a building on several floors, it is recommended to place it
mid-height of the building, but generally in the upper part of the room or area to
cover.
The station should not be used within a metallic closet or in a technical room with
metallic door.
Avoid placing the Sigfox devices in the same room as the station.
Should all the devices be at close proximity, check with the local Operator how to
remotely adjust sensitivity.
5
Avoid installation on the last floor in case of cellular BS on the roof and away
from windows to reduce RF interferers from cellular/broadcasters”
When installed vertically on a wall, the connector must be facing downward.
Outdoor:
It is recommended for pole and wall installation to place the Access Station
Micro above, in the periphery of and facing the connected devices for best
result.
In case the selected site is located in the centre of the area to be covered, the
station can be placed horizontally on its base.
See on the drawings below the area of devices to be covered in blue.

4.4. Outdoor protection
To install the Access station micro outside, or in an environment exposed to high
humidity, dust, or even to prevent thief, you must use the sealing cover to protect
the connectors and the USB dongle if used.
The sealing cover provides an Ingress Protection IP65.
Ethernet cabling must be Cat5e or above, suitable for outdoor use (with drain
wire).

5.2. Power supply
The station is powered with a PoE. The PoE splitter is integrated in the station.
The power is conveyed from the AC/DC adapter through the DC injector and the
ETH cable.
The equipment must be compliant with safety, EMC country regulations.
Customers may need that to re-confirm that the whole system complies with the
EMC directives
5.2.1. Input requirement
Power supply: PoE (passive) 24V DC and 0.75A
Nominal voltage range: 11V DC to 26V DC from the supplied PoE injector
Station minimum input voltage: 10V DC
Max input current: 1A
Injector DC connector: 5.5mm x 2.1mm
5.2.2. Cable length
If using another ethernet cable than the one provided, select a cable CAT5e or
above, shielded F/FTP, SF/UTP, SF/FTP.
Cable length depends on the wires diameter and station consumption.
For guidance:
Conditions Output power supply Gauge size max length
All 20Vdc < V < 26Vdc AWG26 40m
Temp always > 0°C
(no heating required)
20Vdc < V < 26Vdc AWG26 60m

5.2.3. Power consumption
The power consumption depends on the station mode, use of cellular dongle and
external temperatures.
Typical: 2.3W (RX mode) or 4W (TX mode) with Ethernet connection.
Average power consumption with warm up mode: 4.8W
Peak consumption: 7.5W with heating mode
Heating mode: 6.3W (temperature <0°C)
Use of cellular dongle for connectivity: 5W (max)
Maximum: 12.5W (cellular + warm up mode + TX mode)
5.3. Connectivity
The primary Internet connection is provided by the ethernet connection of the
PoE injector. It can be provided by DSL modem, satellite modem, any kind of
backhaul connection or private LAN.
In case of private LAN or direct Backhaul connection, the host network should
receive proper configuration in order to allow the IP communication between
Sigfox Access station and Sigfox Cloud.
Backup connectivity can be provided with a compatible 3G or 4G USB dongle
(see §3 Package contents). Configuration of the cellular connectivity is not yet
available via the Sigfox portal and must be done with Access Station tool (see
next §5.4 Commissioning).
Performance requirement:
Minimum Throughput: 512 Kbit/s (DL) and 128 Kbit/s (UL)
Maximum latency: 2 s

If the light remains flashing orange after 1
minute, check network connection. Check
DHCP server and IT configuration
If the light remains orange after 1 minute,
check DNS servers and policy. Check ICMP
policy /NTP resolution or remove proxy
settings. Check HTTPS connection policy or
certificate. Authorise VPN/IPSec policy
If a cellular USB dongle is used, the led on the USB dongle should be lit or
flashing. Please refer to the USB dongle guide.
