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.

Sealing cover
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

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.
