Wio Terminal LoRaWAN Network Mapper: Plug&Play LongFi Network Monitor for Helium or Other LoRaWAN Network

 

With Wio Terminal LoRaWAN Field Tester + Wio Terminal Battery Chassis, you can stack everything in a compact as Paul used in this video! 

Features

• Ready to go Wio Terminal LoRaWAN Field Tester. No setup, just power it on! The included communication allows a normal use for 3 to 5 years. 
• Compact size, support Type C power bank charge to bring the device everywhere. 
• Monitor the LongFi network performance from the field to verify the coverage and know the different Gateways / Hotspots covering a given place.
• Find the best places to deploy new Gateways / Hotspots. 
• Directly display network and GPS information on the Wio Terminal screen

Description

This Wio LoRaWAN FieldTester is a plug-and-play and all-in-one LongFi network monitor for Helium network. It will help you particularly know how many Hotspots around can be touched for a given position, enrich the network mappers to know each other and share the real network coverage.

It helps to build the global coverage map. This map proves that the network can be used for professional / industrial applications by making sure sensors can be deployed in desired areas. This gives long-term value to our assets. 

In a particular zone where no hotspot has been yet deployed, you can make sure it will be witnessed by some other hotspot and that way verify the viability to deploy new hotspot in excentered zones where the scale reward is higher.

With the Helium Cargo application, you can real-time track yourself or an asset over a covered zone.

Applications 

The Wio LoRaWan Field Tester provides different features, all-in-one:

• Field Tester – it allows to monitor the LoRaWan / LongFi network performance from the field. That way you can verify the coverage and know the different Gateways / Hotspots covering a given place. It helps to find the best places to deploy new Gateways / Hotspots, compare different places to optimize the network deployment. It can show signal strength in real-time and allows the testing of different network parameters.

• Mapper – it automatically transfers the positions to the network mappers – Helium Mappers and Coverage Map – to create a map of coverage. This map is really important to understand where it is possible to use the network. It is a key point for giving trust to the network and motivating the service providers to use it.
• Tracker – it can be connected to tracking services like cargo to track cars, people, assets in real-time.
• Multi-zone: supports AU915, AS923, EU868, US915, KR920, IN865
• Friendly to developers: compatible with over 300 Plug&Play Grove modules to create IoT nodes. The firmware is open-source and can be upgraded like moving a file to a directory.

Principles

When Wio Terminal is connecting to the network, it starts sending messages on regular basis, meanwhile, the onboarded GPS is getting the device’s position in real-time. This message is acknowledged by the network to retrieve the information requested for field testing. Each of the messages is processed by a dedicated application computing advanced Field Testing information later transmitted back to the device. When the GPS signal quality is correct, the location is transferred to the mappers and tracking services.

All the Field Testing information is displayed on the Wio Terminal screen where you can also set up different radio parameters.

Hardware re-use

Wio LoRaWan Field tester is made of standard pieces that can be used for many different applications and you will be able to reuse the hardware for many different applications. If you flash a different firmware on the device than the official build available on the GitHub project you have a risk of losing the device configuration. We won’t be able to provide you with the corresponding credentials and your subscription will be lost. You can at any time configure the device with your own credentials on the helium console following the configuration process described on the open-source project Github.
