Driving is one of the activities that takes a significant part of a person's time, that is why monitoring functional signs is useful for the wellness of the occupants of the vehicle. One of the vital signs that provides more information about the state of the person, is the functional breathing. Compared to other vital signs indicators, breathing is more sensitive to cardiovascular events, emotional stress, physical exertion, or fatigue induced by long time driving, seen as variations in chest and abdomen elongation modes. Technology is a tool that can transcend, from measurement and detection to emotional changes through feedback of sounds, images, or videos to the driver. In this work, an imaging radar system is proposed to generate a topographic map with elongation modes of the driver's chest and abdomen, at 120 GHz. Numerical Simulations have been deployed in order to reconstruct the image of the sensor using spatial convolution. Furthermore, a metronome has been used to calibrate the radar for measure elongations with respect to time, and finally, the system has been tested experimentally in an adult person, to generate a preliminary topographic map of two occupants of a vehicle.

Advanced Driving Assistance Systems (ADAS) have been heavily reliant on on-board sensors to perform automated control of the vehicle actuators. However, having the ability to obtain reliable data beyond the line of sight of these sensors - i.e. wirelessly - might change the game. As a result, the automotive industry envisions a future where ADAS and connectivity converge and collaborate. Platoons might be one of the beneficiaries of such collaboration. While this collaboration improves safety and driving efficiency, it also makes the vehicles vulnerable to cyberattacks. This paper analyses a Cooperative Adaptive Cruise Control (CACC) based platoon model approach, in which communication is vulnerable to Denial of Service (DoS) attack. Considering DOS attacks as consecutive packet dropouts and comparing the behaviour of two CACC-based Platooning variants taking diverse driving scenarios into account. The presented approach shows that platooning can be susceptible to adversarial attacks, which may lead to a collision between vehicles, jeopardising road safety.

The field of vehicular communications has under-gone a significant transformation and is interested in getting more vehicles connected to improve traffic efficiency and safety. The introduction of the millimeter-wave (mmWave) region in 5G New Radio (NR) to achieve higher data rates and the implementation of beamforming techniques to address the issue of higher propagation losses, potentially enables several Vehicle-to-Everything (V2X) use cases for cooperative automated driving and enhanced information services. This paper proposes an approach of beam-based interference assessment for Vehicle-to-Vehicle (V2V) communications at mmWave. The perceived interference level is evaluated for a given beamset covering the full azimuthal range. This information provides useful insights on the quality of communications and the potential re-use rate of scheduled resources.

The growing demand for higher capacities translates into the need for exploring different frequency bands to achieve large-bandwidth antenna transceivers. Millimeter-wave frequency bands could be the most interesting candidate to satisfy the increasing requirements for modern communications. To achieve such good performance, the antennas are required to be multi-beam and highly directive. In addition, optical networks are a widespread solution in backbone networking, providing those large bandwidth requirements without major effect. This paper presents an array located into a focal line of a planar lens, covering the 3GPP band n258 (from 24.25 GHz to 27.5 GHz). The antenna elements are designed to maximize the power transfer from an optical source, with satisfactory results both numerical and measured.

An integrated optical-electrical antenna for a compact

wireless network access node that may directly and seamlessly

connect to fiber in the native radiofrequency format is

proposed and characterised. Full-duplex operation is ensured

by frequency multiplexing downlink and uplink channels in the

standard LTE 22 bands centered respectively at fDL = 3:6GHz

and fUL = 3:4GHz. The antenna design includes a frequency

duplexing structure based on hairpin resonators which at the

relevant frequencies provides simulated levels for return loss

and isolation in between channels better than 20 dB and 30 dB

respectively.
