Hera Guo 13.1 5 == **1.1 What is Outdoor & Indoor signal measuring Solution?** ==
Hera Guo 1.1 6
Hera Guo 13.1 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**.
Hera Guo 1.1 8
Hera Guo 13.1 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.
Hera Guo 1.1 10
Hera Guo 13.1 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.
Hera Guo 1.1 12
Hera Guo 13.1 13 Both dashboards support **data export**.
