1. Introduction

1.1 What is Outdoor & Indoor signal measuring Solution?

To help customers identify optimal sensor placement locations, we have designed a one-click signal strength measurement solution. You only need an LA66 USB LoRaWAN Adapter and a Dragino account.

The outdoor signal measurement solution supports simultaneous testing with multiple gateways. It allows for both individual gateway signal map displays and combined overlays from multiple gateways.

For indoor signal measurement solution , due to the complex layout and numerous obstacles, the solution adopts manual coordinate marking instead of relying on unstable mobile device positioning.

Both dashboards support data export.

1.2 Features

Extensive support
- Only a LA66 USB LoRaWAN Adapter and one Dragino account are needed, the gateway and LNS can be freely matched.
- High-accuracy sensors
- Reliable data readings
Real-Time measuring
- Button to switch receiving data or stop
- Continuous measuring
User-Friendly Interface
- Intuitive dashboard design

1.3 Specifications

Mobile Support: Dedicated mobile app for on-the-go monitoring
Device Manual: LA66 USB LoRaWAN Adapter User Manual
Dragino APP: https://www.dropbox.com/scl/fo/qdiwkpcxc03qu2r2w0g46/AKqR2FByUdkoWZPZh-diYfQ?rlkey=t1a1kwlvr93c1459mz9jifers&st=kji4rdg0&dl=0

2. How to Build？

2.1 Network Structure

2.2 Get Account

To begin, contact your local representative to obtain a customer account or send mail to support@dragino.cc

2.3 Get Device And Configuration

1. Reach out to your local representative to acquire the necessary devices for your signal measuring solution. These devices include:

End Nodes: LA66 USB LoRaWAN Adapter
Gateway(If you want):For data transmission.

2. Burn bootloader & firmware for LA66 USB LoRaWAN Adapter

Bootloader: We ship the LA66 USB LoRaWAN Adapter with a boot loader by default( More detail: https://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LA66%20USB%20LoRaWAN%20Adapter%20User%20Manual/#H1.10A0UpgradeFirmwareofLA66USBLoRaWANAdapter:~:

Firmware: If your device didn't have bootloader or firmware, please burn the latest bootloader & firmware for it in the following way: https://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LA66%20USB%20LoRaWAN%20Adapter%20User%20Manual/#H1.10A0UpgradeFirmwareofLA66USBLoRaWANAdapter:

2.4 Register Devices on LNS

1. Have a check of package box to get DEVEUI/ APPEUI/ APPKEY(OTTAKEY)

2. Register on LNS and replace decoding——ChirpStack_map and TTN_map

If you using other LNS, you can code yourself(The first nine bits of the uploaded data are the flag bit + position, and the rest are the title) or send mail to support@dragino.cc)

2.5 LNS Connection Method

Choose LNS: After log in Dragino platform, click the button "Import-Dragino-map"and choose the LNS you using.

2.5.1 Example ofTTN

Find MQTT in the Other integrations option on the TTN platform
Enter the username in the MQTT Account option
Enter the password in the MQTT Password option
Enter the Public address in the MQTT Address option (do not add the port number)

2.5.2 Example of ChirpStack

MQTT Address: The MQTT server address or the cloud server address which you using.

Subscribe Topic: The default for Topic is: application/chirpstack application id/device/+/event/up(Replace"chirpstack application id" with the one which is actually used)

SSL Certificates: Copy the contents of the certificates and paste them into the linked file below, a total of three certificates are required(Integrated Certificate File demo Download: Demo.pem)

2.5.3 Check: Whether the device is connected to the platform through LNS

Whether the device profile is Dragino_Mapper? Modifyit if not.

3. How To Use?

3.1 Outdoor_Mapper dashboard

Outdoors_signal supports viewing both the signal coverage of a single gateway and the combined coverage of all gateways.

It is recommended that you watch the video together with this instruction to facilitate your actual operation.Outdoor_Mapper

3.1.1 Create the gateway layer.

This solution is pre-configured. Under normal circumstances, when the device successfully uploads information through gateways, it will automatically generate the corresponding assets and put them in the Layer.

The layer will be named after the gateway's IMEI, and you can set a label. At the same time, there will be a dashboard that collects all gateway signals and displays them in an overlay named after the user's registered email address.(Such like :All_signal:$[customer_email])

3.1.2 Measuring

Insert the LA66 USB LoRaWAN Adapter into phone or tablet. Data will be uploaded every 7 seconds based on the tablet's location. Simply move the tablet to measure signal strength from different places.

When the gateway received the first set of data, the current gateway will appear in the left-side list of the gateway interface. When received the second set of data, the current signal strength will be displayed on the right-side map.

The measured data will be displayed in translucent dots of different colors, green represents a good signal, and red represents a poor signal.

3.1.3 End measurement

Don’t forget to unplug LA66 USB LoRaWAN Adapter after finishing the measurement.

3.2 Indoors_Mapper dashboard

Indoors_signal supports measuring and marking the signal strength of all locations on the indoor floor plan.

It is recommended that you watch the video together with this instruction to facilitate your actual operation.Indoors_Mapper

3.2.1 Import the map

Drag the map image here and click √ to import.(Only supports SVG format)

You can place the LA66 device in each room and click on the location on the image to create a new marker to view the signal strength at each location.

Note: After you mark the first location, when you need to go to the second location, create a new mark first, and then go to the second location.

Because LA66 will update to the latest point every time it sends.
If you go to point No. 2 first, and then create mark No. 2, the information of mark No. 1 will be updated to the signal information of the current location.

3.2.2 Delete point

Click the marking points, then click yes.

3.2.3 End measurement
