1. Operating mode
The ACW/LW8-EXT is a LoRaWAN repeater available for ORANGE network. It allows to repeat uplink
and downlink frames from linked devices.
Its integration in the network is transparent as the uplink and downlink frames repeated by the smart
Extender are directly available on the Orange’s Live Objects interface with the repeated devices’ DEV-
EUI. Downlink frames latency towards repeated devices is greater than non-repeated devices due to the
8 seconds reception window’s gap.
The smart Extender only requires a power supply to be operative. Once, the devices’ list is configurated
within the Extender and after that the devices to repeat have realized their respective join phase with
the Extender, the repeating mode is active.
When the list of sensors (White List) is configured in the Extender by the operator via the Back End and
the sensors to be repeated have completed a Join phase with the Extender and have considered the
Mac Command Link_Adr_Req, the retransmission is activated.
Note 1
The Join Request will only be considered when it is transmitted on LC2 SF12 (single channel listening to
the Extender).
Note 2
At the end of the Join phase, the MAC Link_Adr_Request command is sent to the sensor to configure
and freeze the listening and the transmission of the device on LC2, SF12.
The Extender can repeat up to 8 different LoRaWAN devices.
It is compatible with Class A LoRaWAN 1.0, 1.0.1, 1.0.2 devices.
a) Monitoring
The Extender has a proper DEV-EUI and release periodically a keep alive frame, still called monitoring
message. This frame is read by the Extenders monitoring Interface and allows to visualize the following
information:
•SNR and RSSI levels of downlink frames toward the Extender in the Keep Alive Frame LoRaWAN
cycle
•SNR and RSSI sensors levels read by the Extender
The monitoring frame is used to download the repeater parameters and collect the repeating devices
states data. The following parametrization functionalities are available on the Extender:
•Réglage de la périodicité de transmission de la trame de supervision ;
•Add/Delete a device to repeat ;
•Collect the repeating devices states data:
oLast sensor’s emission
oRSSI and SNR levels read by the Extender for this sensor.
oNumber of received and missing frames

(Information not available on the Extenders monitoring Interface)
oCounting of uplink and downlink frames
(Information not available on the Extenders monitoring Interface)
oDevice Address assigned to the devices by the Extender.
(Information not available on the Extenders monitoring Interface)
•Recovery of the Extender state (active or inactive)
All these functionalities are directly done by the Extenders monitoring Interface except for the
mentioned ones.
b) Repeating mode
By default, when the Extender is not emitting neither receiving monitoring frames, it is listening on
868.3 MHz channel permanently. Please note that devices under Extender are configured by itself to
minimize their frequency plan to this unique channel.
•Join phase
If a sensor is part of an equipment list to repeat and it has not been Join with the Extender yet, its
frames will not be repeated.
A sensor mandatorily needs to realize a Join with the Extender in order to enter in the repeating phase.
Note 1
The sensor generates these Join requests on the 3 used frequencies for LoRaWAN sensors (868.1MHz,
868.3MHz, 868.5MHz) and with the Spreading Factor of its own choice. To Join the Extender, you must
wait for the sensor to have emitted the Join request on the 868.3 MHz frequency using Spreading Factor
12.
Note 2
Once the Join with the Extender has succeeded, it will ask the sensor to keep on the 868.3MHz
frequency at Spreading Factor 12. This request will be done on the next uplink frame sent by the sensor
(at an 868.3MHz frequency and Spreading Factor 12) and received by the Extender. Please take note
that the aggregation of the Join and the reception of the first uplink frame may be very long and
completely depends on the sensor’s strategy as a certain number of frames will be lost.
Note 3
The sensor must not be registered on any network for the Join with the Extender to work correctly. It
musts be exclusively registered on the smart Extender (and only on one unique Extender).

ATIM_ACW-LW8-EXT_UG_EN_V1.3ATIM_ACW-LW8-EXT_UG_EN_V1.3
•Repeating phase
If a sensor is part of an equipment list to repeat and that he realized its Join with the Extender, it is in
the repeating phase. Every new uplink frame received is sent to Orange network. When the network
receives a frame from the sensor and the frame from the repeater, the network server will delete the
duplicate and will keep one and unique frame.
Downlink frames received by the Extender are sent toward the sensor within the reception window
indicated to the sensor during the Join.
The Extender is transparent regarding the frames that it repeats. The frames formatting remains the
same. Frequencies and Spreading factors used are different between initial frames and repeated ones.
Frames received by sensors which are not included into the equipment list to repeat will be rejected.
c) Extenders monitoring Interface
The interface allows for the fleet of repeaters deployed:
•addition/deletion of an Extender on the client account of the Extenders monitoring Interface
•addition/deletion of the sensors to repeat for the smart Extender
The Extenders monitoring Interface is accessible on the following URL:
https://backend-smartExtender-prod.noprod-b.kmt.orange.com/
Note
Les identifiants pour se connecter à L’interface de gestion des Extenders sont les mêmes que ceux du
compte Live Object.
11
ATIM_ACW-LW8-EXT_UG_EN_V1.3ATIM_ACW-LW8-EXT_UG_EN_V1.3
d) Live Objects Interface
Live Objects Interface remains the point of interface with the sensor. It provides sensors data reading
and relay information to the sensor through downlink frames.
The connexion URL to the Live Object portal is: https://liveobjects.orange-business.com/#/dashboar
e) Solar panel specifications
The solar panel version is equipped with a battery continuously recharged by the solar panel. An
automatic cut-off device stops the repeater when the battery charge level is insufficient.
On restart, the repetition cycles automatically resume, there is no new Join phase to the network (unless
the Extender has never joined the network). A new Join phase can be forced if necessary. This requires
opening the case.
The switch of the card must be placed on OFF for a period of 30 seconds then returned to ON. On
shutdown and restart (and provided that the network has been previously joined), a life frame
(supervision message) is sent to indicate the shutdown and activation of the Extender.
On the latest versions ON / OFF can be done approaching a magnet close to the interrupter (on the side
of the REED sensor’s casing)

2. ACW/LW8-EXT Installation
Commissioning procedure of the Extender requires the following steps:
•Registration of the Extender on the Orange network;
•Registration of sensors on the Extender;
•Installation of the Extender on the field;
•Sensors restart
a) Network provisioning on the ORANGE of the Extender
Unplug the power cable of the Extender and connect on the Extenders monitoring Interface URL.
On the « Park » window, select « Add an equipment ».
On the Adding window, fulfill the DEV-EUI, APP-EUI and APP-KEY parameters provided by ATIM. The
« Name » field is free. We advise you to keep a 1-minute period for the keep alive frame (monitoring
frame) to ease the Extender parametrization. The Rx1 delay must be kept at 8 seconds.
13
ATIM_ACW-LW8-EXT_UG_EN_V1.3ATIM_ACW-LW8-EXT_UG_EN_V1.3
Click on Save. When you return to the home page, the Extender is now visible and has the registered
status.
Start the Extender. It will switch to “Activated” state when it reached the network.
Note
For the solar panel version, the product must be positioned for several hours in the sun to be properly
charged. When the load is sufficient, the product will perform its Join phase with the network. If the
product is already loaded, the Join phase may take more than an hour.
The Join phase can then last more than 1 hour if the charge has not been operated beforehand.
b) Sensors provisioning on the Extender
•Adding a sensor / Migration of sensor
During this phase, the Extender is connected to the Orange network. The keep alive frame (monitoring
frame) period has to be fixed at 1-minute. The Extender must be placed in a well-covered zone.
The access to sensors is not required. This phase will be ideally realized before the deployment on site.
On the « Park » window, select the Extender and then reach the « Equipment » window.
Select the « Migration from Live Objects » button if the sensor was already commissioned on Live
Objects or « Add an equipment » if the sensor has never been commissioned.
In case of a migration, the APP-KEY will be required. Click on the « Migration from Live Objects » and
select the equipment to migrate in the list.
14
ATIM_ACW-LW8-EXT_UG_EN_V1.3ATIM_ACW-LW8-EXT_UG_EN_V1.3
Enter its APP-KEY:
In this case of adding, the whole sensor parameters are required (DEV-EUI, APP-EUI, APP-KEY). Click on
the « Add an equipment » button and enter these parameters:
15
ATIM_ACW-LW8-EXT_UG_EN_V1.3ATIM_ACW-LW8-EXT_UG_EN_V1.3
The new equipment is added to the equipment list and will appear « commissioning in process » on
the smart Extender. This commissioning phase will take a few minutes (if the keep alive frame is set on
1-minute).
The equipment is effectively registered when the state switches to « registered on the smart Extender ».
If after 20 minutes or so, the equipment does still not appear as registered, we recommend you to force
the deletion of the equipment and restart the operation.
•Deletion / Migration of a sensor
During this phase, the smart Extender is connected to the Orange network. The keep alive frame
(monitoring frame) period must be fixed at 1-minute. The smart Extender must be placed in a well-
covered zone. The access to the sensors is not required.
16
ATIM_ACW-LW8-EXT_UG_EN_V1.3ATIM_ACW-LW8-EXT_UG_EN_V1.3
Note
The sensor will have to be restarted to be connected to the new network.
c) On site installation of the Extender
The localization of the Extender must be chosen to have a comfortable Orange network coverage to
repeat that network correctly. During this phase, the keep alive frame (monitoring frame) period must
be fixed at 1-minute to ease the installation.
An access to Live Objects and to the Extenders monitoring Interface will allow you to visualize the
reception signal levels and to check the correct repetition of the sensors.
When a good localization has been found, the Extender can be started. Once, it has connected to the
Orange Network, keep alive frames (monitoring messages) will be sent periodically. We can visualize on
Live Objects the RSSI and SNR levels as well as the Spreading factor (SF) of keep alive frames of the
Extender (a couple of frames need to be analyzed to get a good vision of the network quality). The SF
could be in between SF7 and SF9. If the SF is fixed on SF9, the SNR and RSSI levels need to be checked.
A positive SNR will show a good reception quality. If the SF is lower than SF9, the quality of transmission
should also be good.
Once, the localization of the Extender is fixed, a restart must be done on the sensors to repeat.
These ones will progressively Join the Extender, but this operation may be long and depends completely
on the equipment Join’s strategy. Depending on the sensors, this operation can last from a few minutes
to several hours.
We can follow the sensors’ Join to the Extender on the Extenders monitoring Interface under the
« Journal » Extender tab. The messages « Advertise Join reception » show that a sensor has done its Join
with the Extender. The « Equipment » Extender tab allows to visualize the sensor reception levels from
the Extender (RSSI and SNR from the Extender) as well as the last message. The sensor switches to
« active » state from the first reception frames repeated by the Extender.
Note
Once the installation is done, the periodicity of the keep alive frame (monitoring frame) needs to be
minimized. We advise to reduce the configuration to a daily frame to allow a permanent listening of the
sensors to repeat.
d) Keep alive frame periodicity setting
The « Configuration » Extender tab allows to modify the setting of the periodicity.
In the « Parameters » section, click on the « modify » button and enter the new target field.
This value will be applied from the emission of the next keep alive frame. To apply other settings on the
Extender, we advise you to modify this value to reset for an emission every minute.
