5 == **1.1 What is Outdoor & Indoor signal measuring Solution?** ==
6
7 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**.
8
9 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.
10
11 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.
12
13 Both dashboards support data export.

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

226 === **3.1.1 Create the gateway layer.** ===
227
228 (% class="wikigeneratedid" %)
229 **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.**
230
231 (% class="wikigeneratedid" %)
232 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])
