In this paper, for the first time, we propose two new solutions to boost the data rate between
small connected objects such as glasses and cams and the 5th generation (5G) mobile …

Railways are facing an ever increasing needs for safe and secure wireless communications
with the generalisation of automatic and driverless trains. In this context, frequency scarcity …

Assuming the hybrid mmWave architecture and the 3GPP antenna model, we propose a
new ULA-like array configuration called array of slanted subarrays (AoSSA) by allowing a …

The mmW4Rail project explores the millimeter wave band for train-to-train and train-to-
infrastructure communications. It involves the definition of new channel models based on …

There are two methodologies to realize 3D MIMO for FDD LTE, MU‐MIMO‐based virtual
beam (VB), and four‐cell soft‐split cell (SSC), which beamforms four logical cells in one …

Ambient backscatter communications have been introduced as low-power communications
for green networking. This technology is very promising as it recycles ambient radio …

Massive multiple-input multiple-output (MIMO) is considered as one of the building blocks of
5G. This technology offers higher capacity, faster speed and improved spectral and energy …

This paper explores the feasibility of direction of arrival (DoA) measurements with high
angular resolution using a hybrid antenna array. The original concept is based on the …

With the development of digital technology and the Internet of Things, there is a growing
need for transmission rates per user, capacity, security and flexibility of communications …

Due to the very soon obsolescence of the current train-to-ground communication system
used in Europe, 2G-based GSM-R will be replaced by a 5G-based communication system …
