Quality of Service (QoS) and Quality of Experience (QoE) – but what is actually behind these terms?

Industry 4.0, IoT, automotive, the use of smartphones – each of these applications has demands on the network. Countless data streams require many technologies working in a network. Data analysis and remote visualization, these are just some of the technical applications.

Quality of Service (QoS) is composed of several properties that make up the performance in data traffic.
Especially for telecommunication companies it is important to provide a flawless QoS for customers. At EST Solutions, we focus primarily on this area. With specialized partners, we have already implemented some large, successful projects for telecom companies and their end customers. In this context, it is particularly important to consider not only network security, but also quality of service. It includes the measurement of the overall performance of a service, for example, transmission speed and bit rate, availability as well as data loss and delays.

QoS also plays an important role in the roll-out of 5G networks – the network that provides the efficiency and speed that we, and the demands of individual services, need today. So  what is particularly important here:  the reliability of the application. 

And, of course, not to forget: Customer satisfaction – Quality of Experience (QoE). QoE is similar to QoS, but differs in terms of dimensioning:

While QoS measures hardware and software properties, QoE assesses user satisfaction. Again, factors such as efficiency, security, trust and user-friendliness play an important role. It is therefore in the interest of every company to maximize not only its QoS but also its QoE, and this will determine its long-term success. End-to-end Quality of Service and Quality of Experience solutions – together invincible!


With selected partners, EST Solutions supports service providers in all access technologies to deliver the best quality (and QoS & QoE) to their customers!
