RAK7590 Field Tester Pad Datasheet

Product Overview

The RAK7590 Field Test Pad is a handheld device designed for indoor and outdoor LoRaWAN network testing and deployment verification. It enables real-time measurement of uplink and downlink signal quality (RSSI, SNR) and packet loss rate, helping users evaluate network coverage during installation or maintenance.

This device features a large LCD screen for on-device parameter configuration and test result visualization. With its built-in GPS module, users can associate test data with precise location information and view signal distribution on the map. It also supports test report viewing and downloading for efficient data tracking and comparison.

The RAK7590 works with the Field Test Data Processor Extension on WisGateOS 2, which performs backend data parsing and analysis to deliver a complete LoRaWAN® network testing workflow from data collection to performance evaluation.

Parameter	Description
Test Label	Displays the test label. NULL means no label is applied. If a labeling test is being conducted, the input label will be displayed here.
Uplink Status	Displays the status of uplink transmission: - Join Success: Device successfully joined the network. - Join Failed: Device failed to join the network. - Send Success: Packet sent successfully. - Send Failed: Packet failed to send. - Sending (x/50):Indicates the number of uplink packets sent during the labeling test, out of the total being sent. - Idle: Device is not actively communicating.
Last Downlink Received	Shows the time since the last downlink packet was received (e.g., "XXs ago"). - Green text: Last uplink was successful. - Red text: Last uplink failed.
System Time	Displays the current system time.
Battery Level	Shows the battery percentage of the device.
Uplink/Downlink RSSI/SNR/Packet Loss Graph	Displays the real-time graph of RSSI, SNR, and Packet Loss Rate for the last 20 packets. Switch between Uplink and Downlink by clicking the tabs.
GPS Signal	Displays GPS coordinates if available. If there is no GPS signal, it will show No GPS.
Start/End Labeling	Button to start or end the labeling test. Clicking Start Labeling begins the test, and once the test is running, the button changes to End Labeling to stop the test.
Start/Stop Test	Button to start or stop the test. Clicking Start Test begins the non-label test, and once the test is running, the button changes to Stop Test to stop all ongoing tests.
Uplink Statistics	Displays radio signal quality metrics from the device to the gateway: - RSSI (Received Signal Strength Indicator) - SNR (Signal-to-Noise Ratio) - Packet Loss (Percentage of uplink packets lost) - Data Rate(The speed of data transmission, typically measured in bits per second)
Downlink Statistics	Displays radio signal quality metrics from the gateway to the device via LinkCheck mode: - RSSI (Received Signal Strength Indicator) - SNR (Signal-to-Noise Ratio) - Packet Loss (Percentage of downlink packets lost) - Data Rate (The speed of data transmission, typically measured in bits per second)
Gateway Information	Information about the connected gateway: Gateway Count: Displays the number of gateways that received the uplink. Gateway EUI: Shows part of the EUI (unique ID) of the nearest gateway to help identify it easily. Max Distance: Farthest gateway (minimum unit 250 meters). Min Distance: Nearest gateway (minimum unit 250 meters). Note: GPS must be available for distance calculation.
Current LoRa Details	Shows current LoRa settings and configuration: Band: The LoRa frequency band being used. ADR (Adaptive Data Rate): Indicates whether ADR is enabled or disabled. TX Power: The transmission power setting, typically expressed in dBm. TX Interval: The interval between transmissions, typically expressed in seconds.
