Step 4: Track Your Position
This step shows you how to use the network tester to report your GPS coordinates to the network tester webpage.
Put the tester in GPS Test mode
On the network tester's home screen, select GPS Test. The status bar and number at the top display the strength of the connection. The number reports the signal strength (in dBm) of the gateway's beacon, as measured by the network tester.
The banner along the bottom scrolls incrementally each time the network tester transmits. The message-number increments upward with each transmission (and rolls over at 60). After each transmission, the three asterisks associated with the current message-number will become ACK to indicate the message was successfully received by the gateway or ERR to indicate the network tester did not receive acknowledgment from the gateway.
For example, in the picture below, GPS message 01 was acknowledged by the gateway and the network tester is transmitting message 02.
Take a walk.
Take the network tester for a walk. While you walk, watch the connection strength to get an idea of the range you're getting from the gateway. The network tester will probably remain connected down to a signal strength of about -120 dBm.
If your network tester happens to lose its connection, it will beep and the D1 diode will go out. Walk back toward the gateway. The network tester will automatically reconnect when the signal becomes strong enough.
Look at your journey.
When you have finished walking around, take a look at the network tester webpage. The GPS coordinates of each transmission are recorded on the map in the main window, color coded to represent the connection strength. They show the path you just walked.
The list box on the left-hand side of the page shows the details of each successful uplink. You can download these data, either as *kml or *csv, by clicking on the word KML or CSV.
