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. All you need is one **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 display and combined signal overlay from multiple gateways.
10
11 For **indoor signal measurement**, due to the complex layout and numerous obstacles, the user needs to walk to a suitable location before starting the measurement. Measurement points can then be marked on an indoor map, with flexible options to add or remove markers.
12
13 Both dashboards support **data export**.

230 === **3.1.1 Create the gateway layer.** ===
231
232 (% class="wikigeneratedid" %)
233 **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.**
234
235 (% class="wikigeneratedid" %)
236 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.
237
238

246 Click the center button on the right to add a gateway layer. (Please create all devices that can accept the current LA66 USB LoRaWAN Adapter frequency band; otherwise, the received data will not be displayed.)
