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
radio 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 recommendation
Access Station Micro has been developed for indoor and outdoor operation.
For temporary location, the base station is perfectly stable sitting on a table, a desk
or a shelf. For permanent installation, we recommend using the mounting kits for
long-term fixation.
For outdoor operation, the adjunction of sealing cover is mandatory to ensure
waterproofness (see §4.4).
4.1. 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.
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
Minimum physical separation

4.3. Sealing Cover
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 theUSB dongle if used.The sealing cover provides an Ingress
Protection IP65.
Note: Ethernet cabling must be Cat5e or above, suitable for outdoor use (with
drain wire). For more details in cable types and maximum length see the power
supply § 5.2
4.4. 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.
4.4.1. 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.
To ensure a maximum of performance, you must ensure to:
•Avoid placing the Sigfox devices in the same room as the station.

8
•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”
Note: When installed vertically on a wall, the connector must be facing downward.

9
4.4.2. Outdoor:
For outdoor deployment, it is recommended to place the Access Station Micro
above, facing and in the periphery of the connected devices for best result.

5.Connection and commissioning
5.1. Interface
5.2. Power supply
The station is powered with a passive 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 (all provided in the box).
Customers may need 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
Note : The station cannot be powered with IEEE 802.3x active PoE
routers/injectors.
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.
Ethernet cable length depends on the gauge size and station consumption.
For guidance (AWG22 to AWG26):

Standard installation (24v):
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)
Cable length < 40m
(without heating,
length < 60m)

12
5.3. Connectivity
The Access Station Micro needs Internet access to operate.
It can be connected via Ethernet cable (RJ45 port on PoE injector) or Cellular USB
dongle (USB port on station).
When both connections are used to improve link robustness, the Ethernet one is
automatically set as primary and Cellular is set as secondary backup.
5.3.1. Ethernet connectivity
Ethernet connection of the PoE injector 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 to allow the IP communication between Sigfox Access
station and Sigfox Cloud.
Performance requirement:
Minimum Throughput: 512 Kbit/s (DL) and 128 Kbit/s (UL)
Maximum latency: 2 s

5.3.2. Cellular connectivity
As an alternative or backup, connectivity can be provided with a compatible 3G
or 4G USB dongle (see §3 Package contents) and SIM card.
Before the first connection, the cellular connectivity must be configured locally
with the Access Station Utility application according to your SIM card
subscription parameters.
5.4. Commissioning
Commissioning of the station is done online by the Sigfox Operator via the
Backend interface.
Pre-commissioning, modification of network settings and registering site location
can be done with the Access Station Utility application.
Access Station Utility in available for download from Google Pay to suitable
phones or tablets.
