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**.

220 === **3.1.1 Create the gateway layer.** ===
221
222 (% class="wikigeneratedid" %)
223 **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.**
224
225 (% class="wikigeneratedid" %)
226 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.
227
228
229 (% class="wikigeneratedid" %)

236 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.)
237
238 For example, here we created a gateway with the ID a84041fdfe27e8fa
239
240 You can click here to modify the gateway layer ID (it must correspond one-to-one with the gateway ID that will receive the data).
