NETW'O

Presentation


Netw'o is a range LoRaWAN tester. It presents simply by leds the quality of the uplink and downlink. It could be associated to a smartphone via BLE to control and monitor more precisily the information about the link budget.

Thank to this BLE feature the Netw'o can be remotely manage to be in real condition of an installation of device ( close door, high position,...). The result of the test with the localisation point, in json or csv, can be shared directly through the smartphone (email, social network,...).

User guide


  • Set the devEUI appEUI on the network on which you want to test the RF range.
  • Start the device by putting the magnet behind the "ILS" sticker during 1s. Device rings until associating to the network.
  • 5 link budget frames are sent just after association with 15 seconds of delay between.
  • After transmitting, there is 2 indicators: the first one is the quality of the Transmission, the second one is the quality of reception.
    • Transmission:
      • Red: The signal transmitted by the device is VERY BAD receipt by the gateways. Risk of loss a lot of uplink. Try to put the device higher or in other place.
      • Orange: The signal transmitted by the device is BAD receipt by the gateways.
      • Green: The signal transmitted by the device is GOOD receipt by the gateways.
      • GreenGreen: The signal transmitted by the device is VERY GOOD receipt by the gateways.
    • Reception:
      • Red: The signal received by the device is VERY BAD. Risk of loss a lot of downlink. Try to put the device higher or in other place.
      • OrangeThe signal received by the device is BAD.
      • GreenThe signal received by the device is GOOD.
      • GreenGreenThe signal received by the device is VERY GOOD.
  • Put a magnet quickly on the  "ILS" sticker to relaunch a burst of link budget transmitting.
  • Switch Off the device by putting the magnet behind the "ILS" sticker during 5s.

Battery


  • When the battery is over, you can replace it by 2 x 1.5V AA battery.
