Measurements for Modern Networks and Telecommunication Systems
In a world where the possibility to have a broadband connection is a fundamental need, countries where this possibility is not warranted risk to have many problems for their development. For this reason, communication systems and technologies involved in computer and telecommunication networks play a very important role in a society that needs to be more and more connected at very high data rates.
To satisfy these requests, several technologies have been developed, especially in wireless and cellular communications, like 3G and 4G systems and more advanced technologies are under design and test, as 5G.
Thanks to these technologies, we can use (i) wireless sensor networks for many applications, (ii) access to advanced services like Video streaming, VoIP and so on. They have given the possibility to make real the idea of Internet of Things (IoT). To give a very good Quality of Service (QoS) to the users, it is fundamental to execute several measurements to avoid for example spectrum usage efficiency issues, electromagnetic interference and coexistence problems. In particular, in such contexts, measurements performed at different layers from physical to application of ISO/OSI stack and cross-layer analyses become fundamental for developers, testers, and users of such technologies and services.
As an example, the metrological characterization of transmitters and receivers chain operating at even more increasing frequencies (with particular reference to 5G) imposes new measurement challenges to be adequately faced by defining suitable measurement procedures and measurement setup able to warrant accuracies suitable for the purposes.
As computer networks regard, Quality of Experience (QoE) and Quality of Service (QoS) are interleaved concepts which enable to estimate the degree of satisfaction or annoyance of the user of an application or service. Objective measurements of QoS are today correlated to QoE to achieve an objective estimation of user’s perspective of the overall quality of the provided service. In such context, the metrological characterization of such indexes is required to provide a confidence level to such important quantities.
Furthermore, the advent of new wireless communication technologies unveils the current spectrum scarcity problem due to the static frequency allocation policy. A possible solution to this increasing demand for spectrum usage is the development of dynamic spectrum access paradigms that can be easily implemented with Cognitive radio devices. This technology surely represents a possibility to improve the spectrum usage efficiency for many applications (civil, military, vehicle to vehicle communications, to cite a few). In such a context, measurements are fundamentals for designing and developing new methods to improve the capability and accuracy of cognitive radio terminals in spectrum sensing also under critical Signal-to-Noise ratio.
In such scenario, the topics of interests for this special session include, but are not limited to:
- Measurements on 5G;
- Measurements for computer networks;
- Methods and techniques for networks performance assessment;
- QoE and QoS assessment in computer networks;
- Cognitive radio development and measurements;
- Measurement for coexistence and interference analysis in wireless networks;
- Measurement on RF telecommunication systems;
- Measurements on cellular networks and mobile terminals.
The special session is promoted and supported by TC-37 “Measurement & Networking” of IMS.
