Introduction

In this document, you’ll be able to see Wirepas Massive technology live in two different networks using Wirepas Network Tool. You will also see Wirepas Positioning Engine in action.

What you'll learn

  • See Wirepas Massive decentralized technology in action:
    • see network topology
    • automatic routes
  • Basic use of Wirepas Network Tool client for network monitoring and device management including Wirepas Positioning Engine
  • Basic understanding of Wirepas Gateway to cloud reference architecture

What you’ll need

  • A computer running Windows 10 operating system
  • Wirepas Network Tool client v4.0.0.1236 (Installation procedure is described below)
  • Internet access on your PC with the following ports open:

Source

Destination

Port TCP

Customer Computer (WNT Client)

WNT Backend (AWS)

8811 (web socket)
8812 (web socket)
8813 (web socket)
 8886 (web socket)

Ensure that any firewalls between the WNT client machine and backend instance are correctly configured to pass traffic on those ports.


Getting Started

In this demo you will be able to see live operation of 2 Battery Operated Wirepas networks at 2 different locations 

Network 1: Tampere area, Finland

Outdoor test network in 2.4GHz

  • 1 Gateway with cellular backhaul
  • 150 battery operated nodes
  • Outdoor environment with complex chain topology

Network 2: Grenoble area, France

Building test network in 2.4GHz

  • 2 Gateways with Ethernet backhaul
  • 56 battery operated nodes, 55 anchors and 5 tag
  • In building network with multiple buildings & floors
  • Asset tracking with localization of tags
  • Tags with sensors

Operation Principle

In this demo, 2 live and independent networks are connected to a single Wirepas Backend instance hosted in AWS infrastructure as example. 

The demo consists of:

  • Live Wirepas Massive networks connected to Gateways
  • Gateways connected to the cloud via either Cellular of Ethernet access. Gateways communicate with he Wirepas Backend via MQTT protocol
  • Wirepas Backend collects and processes messages from the network
  • Wirepas Network Tool visualization client is connected to the Wirepas Backend via Internet and is used to visualize and monitor the networks

Wirepas Massive networks and Gateways

  • Live test networks with Nodes and Gateways
  • Fully automatic and decentralized network
  • Nodes are sending sensor data, positioning data and or diagnostics data to the backend via Wirepas Massive network
  • Gateways are sending and receiving network data from the cloud backend using Wirepas open source gateway API (https://github.com/wirepas/backend-apis )

Wirepas Backend

  • Wirepas Backend is running the Wirepas Network Tool backend and Wirepas Positioning Engine
  • Receives diagnostic packets from nodes. Stores and processes for the WNT Client
  • Allows to manage network, sets configuration , manages OTAP ….
  • Can run in Cloud or On-premise. Runs on AWS in this demo.

Wirepas Network Tool client software

  • PC Application to Monitor and Manage Wirepas Massive network
  • Allows to see network behavior, topology, frequencies … based on nodes diagnostics
  • Supports map tools for asset tracking application.
  • Supports Firmware updates of nodes as well as network parameters setup
  • API between WNT Backend and WNT Client fully documented

Getting Started with Wirepas Network Tool

How to install & Start WNT Client

Please refer to the Wirepas Network Tool Client user guide [1] "section 4-Getting Started" for detailed installation procedure.

High level instructions:

  • Download Wirepas Network Tool client v4.0.0.1236 from Wirepas Developer Portal
  • Launch installer and follow installation
  • At first launch, the WNT will ask for a server:
    • Enter wss://wirepasdemo.prod-wirepas.com:8813 and click ‘Connect’
    • Next window: Username: demo / Password: wirepas

  • Then click ‘Log In’

Once logged in you should see the Wirepas Network tool User Interface. In case of any issues there, please make sure you have Internet access and ports properly opened as per the previous requirements.

Starting Wirepas Network tool Client - Overview

In below section we will describe the different screens available in Wirepas Network Tool client. Please refer to the Wirepas Network Tool Client User Guide [1] for a more detailed description of the Client features and usage.

Overview screen allows you to select active networks and see a summary of the nodes:

Node view

Node view gives a list view of all node within a selected network. For each node you can see its ID, role, mode and location.

Should you want more details, just double click on a node to see detailed view:

  • You can then select some metrics like Hop count, Link Quality, Frequency in use and see historical data.
  • You can also click on “Show in map” or “Show in topology” to check node’s physical and logical position.

Map View

Map view gives you the logical mesh connection between nodes on a Map view. With this view, you can see how the connection between nodes are established automatically by Wirepas Massive.
 Lines between nodes represent the mesh connection, the ‘%’ on the line represents the link quality.

In this example the Low latency nodes are the gateways also called Sink in Wirepas networks. Those links are dynamic and topology might change depending on radio environment.

Nodes with light colors are located on another floor. Use the menu on top right side of the map to select your building and floors.

You can also see live position of mobile tags computed by Wirepas Positioning Engine

Topology View

Topology view allows to see the Mesh tree topology for a selected network and gateways (Sink). Specific sink shall be selected to visualize topology.

Click on “Show organic” or ‘Show hierarchy” to see either organic or hierarchical view.
 White nodes on top of the trees are Gateways

Test Networks description
