You Already Know Quality of Service

Quality of Service (QoS) simply means the network’s capability to support applications.

Even though you would not be familiar with QoS as a technical term, you have most certainly experienced bad QoS one way or another.

QoS problems are so common that many just try to get along with them. It does not have to be like this.

Quality of Service Problems Are Costly

Network QoS problems can cause expenses, delays, and damage.

These problems are difficult to solve without appropriate tools.

Reveal the True Network Performance with Qosium

This is where Qosium steps in. Qosium is the ready-to-go network measurement/monitoring solution for figuring out the true Quality of Service.

Qosium is a pure software solution. No extra hardware is needed.

Qosium Fits Many Use Cases

It’s not just a network diagnostics tool. You can use Qosium in a dozen different ways. Network QoS shows up in different ways but everyone can benefit from Qosium.

Learn to understand and visualize network performance.

Locate bottlenecks and problem areas in your network.

Discover how applications and services really perform over the network.

Test and validate network performance of new products and devices.

Map network performance on a geographical indoor or outdoor area.

Conduct continuous monitoring with automated alerts and actions.

Verify that network connections allow uninterrupted application usage.

Find out user satisfaction with Quality of Experience metrics.

What Makes Qosium Unique?


Qosium measures real application QoS over every network technology.


Qosium lets you see network problems, and even react to them, immediately.

100 % Software

Qosium is all software. No need to install additional hardware.


Qosium installs to computers, mobile and embedded devices, network devices, and servers.


Qosium measures existing application traffic silently in the background.

Easy to Use

Qosium has extensive documentation and learning material available.

How It Works

Step 1: Install Qosium Probes

Qosium Probe is a measurement agent that taps into network traffic. Install Probe to each network device that you want to act as a measurement point.

Step 2: Start Measuring

Measure network performance from application perspective over any path between any Probes.

Qosium Is for You Too

Not into network technologies? No worries. Qosium is widely used by people other than network experts. It’s no wonder since network technologies are present in all industries today.

Find and expand the topic below that matches your current situation to see how you can benefit from Qosium.

We want to monitor how our applications/services work over networks

Qosium is a passive system, making it especially helpful for continuous monitoring of your applications’ QoS. Qosium does not need any support from your applications or network technologies, making it a fully transparent way to know how well your applications work over networks all the time.

  • Let Qosium Scopemon carry out continuous monitoring and get notified on degraded network conditions
  • The measurement results are stored for later analysis with Qosium Storage
  • Measure directly or analyze stored results later and get detailed information on QoS parameters with Qosium Scope

Case Example: Fujitsu Finland

Qosium is part of Fujitsu Finland’s Application Performance Management (APM) monitoring to ensure the availability and performance of applications over networks. The detailed data from Qosium allows Fujitsu to react to even the most minor connection quality deviations for their customers’ applications.

I need to detect and locate problems in our network

Qosium measures connection quality from the perspective of real applications/services. This makes it especially suitable for ensuring the quality of operational networks.

  • Install Qosium Probes to locations in the network that are essential for discovering network problems.
  • Conduct manual measurements with Qosium Scope or monitor continuously in the background with Qosium Scopemon. Results analysis is made simple with Scope and/or Qosium Storage
  • Often, the first step is to know that is the problem due to network or the application/service itself. Starting analysis with two measurement points, e.g., between end-points is often useful and adding new measurement points to analysis can be taken upon need.

Case Example: Modern Factory

A modern factory uses autonomous robots in daily production. The robots rely on a private LTE network. They were facing issues with the robot operations, and Qosium was deployed to discover the root causes. Continuous monitoring, together with robot location information, revealed the weak performance areas inside the factory. As a result, a more productive factory environment was obtained.

We are developing a new network product but it needs to be tested

Qosium provides you with detailed information on how your product performs in networks. This information can be used, for example, to:

  • Prove that the product meets the requirements set for it
  • Ensure that the product can manage varying network conditions as expected
  • Provide unquestionable data to be used in marketing

Case Example: European Car Manufacturer

Cars get connected rapidly. A large European car manufacturer added a new device to their vehicles, whose operation relies on a mobile connection. Kaitotek helped them discover the most optimal install location for their device with Qosium. When connectivity is essential, the location of the device for the best possible coverage is necessary.

I want to see the quality of our wireless network on a map

Qosium Scope and Qosium Storage come with a feature to visualize measurement results also on a map. Heatmap drawing is helpful to find problem areas and verify network quality on a location basis, whether indoors or outdoors.

  • Locate places where the network provides weak QoS
  • Visualize connection quality in real-time while moving
  • Learn how base station locations and network configurations affect network quality

Case Example: Port of Oulu & Herman Andersson

Herman Andersson’s port machines are deployed with automated Qosium monitoring. While the machines use their operations, the Qosium measurements in the field feed Qosium Storage constantly with results. The results data is processed to create a situation awareness of the used private mobile network. Map visualization helps locate problem areas in the network quickly.

I teach/study/research network technologies

Qosium has its roots in research. We first developed it to support various telecommunications studies. Therefore, Qosium has a lot to bring to education and research.

  • Get accurate data on the performance of telecommunications systems
  • Integrate real-time QoS/QoE data into your intelligent solutions
  • Teach network traffic and what QoS means with the help of Qosium’s visualization features

Case Example: VTT

VTT Technical Research Centre of Finland Ltd. has used Qosium for years in a wide variety of research and customer projects. The Qosium usage varies from manual measurement campaigns to automated measurements as part of AI solutions that, e.g., dynamically control applications and network configuration and resources.
