Abstract

Advancement in the 5G mobile communications network

Rogier Noldus (Ericsson)

The standardisation (by 3GPP) of the first release of the 5G mobile communications network was completed in 2018. Both the radio access network (RAN) and the core network have evolved, compared to the 4G network. The introduction, by operators, of 5G network technology has often led to complex integration of 4G and 5G, where the network may e.g. comprise a combination of 4G RAN and 5G RAN, coupled to a 4G packet core network. In this process, operators need to support a multitude of communication technologies (2G, 3G, 4G, 5G). Operators want to start decommissioning older generations (2G and/or 3G) and proceed with 4G and 5G only. One of the many aspects of this evolution is that the 4G network (and later generations) does not support circuit switched technology. Evolution in the 5G network continues, both in the RAN (e.g. new frequency bands) and in the core network. There will be a period of overlap where technology for “5G Advanced” is developed, alongside technology for 6G. The architecture of the 6G network is still unknown, but fundamental research has already started. This presentation will present a brief overview of the 5G network architecture (radio, core), the challenges and the evolution. The presentation will also provide a preview of the ambitions for 6G.

Bio

Rogier Noldus is principal solution architect at Ericsson Telecommunicatie, Rijen, Netherlands. His main line of work is (mobile) communication network architecture and services. He is the (co-) author of the books “CAMEL: Intelligent Networks for the GSM, GPRS and UMTS Network” and “IMS Application Developer’s Handbook”. He is in addition part-time lecturing at the TU Delft (Mobile network architecture), where he is also pursuing (part-time) a PhD in the area of network topology optimization. Rogier holds a BSc (electrical engineering) from the Hogeschool Utrecht, Netherlands, and an MSc (telecommunications) from the University of the Witwatersrand, Johannesburg, South Africa.

Abstract

Wideband interference nulling for ultra-reliable wireless intra-aircraft communication

Erik Bertram (TU/e)

In the context of the ADENEAS research project, we have been looking for ways to increase reliability of wireless communications to aid in reducing the wire bulk inside of aircraft. Current aircraft are fitted with an extensive and heavy wiring system, connecting all the various sensors and actuators inside the aircraft, of which many have some sort of reliability requirement. The main objective of this effort, is in reducing the overall weight of the aircraft, in turn reducing fuel consumption. To get a better picture of unusual propagation properties inside the aircraft, channel measurements have been conducted as an aid in finding suitable solutions. These measurements have led to a proposed architecture for separating the different propagation paths inside the aircraft, to avoid interference and improve the overall hardiness of the system. In order to test the viability of this solution, an integrated circuit implementing a part of the required functionality has been designed for future testing and verification of the concept.

Bio

Erik Bertram received both his MSc and BSc in Electrical Engineering from Eindhoven University of Technology, graduating in the integrated circuits group, investigating topics on radio astronomy and RF power amplification. Currently he is pursuing a PhD within the same group, focusing on novel circuit ideas to overcome challenges in wireless communications.
