MmWave channel stationarity analysis of V2X communications in an urban environment
Vehicular communication channels are subject to high nonstationarity mainly characterized by the scatterers’ and/or transceivers’ high mobility. In this sense, this letter presents a characterization of the channel ... -
Performance evaluation and interference characterization of wireless sensor networks for complex high-node density scenarios
The uncontainable future development of smart regions, as a set of smart cities’ networks assembled, is directly associated with a growing demand of full interactive and connected ubiquitous smart environments. To achieve ... -
Propagation models in vehicular communications
In the advent of becoming reality, the era of autonomous vehicles is closer than ever, and with it, the need for faster and reliable wireless connections. The propagation channel determines the performance limits of wireless ... -
A radio channel model for D2D communications blocked by single trees in forest environments
In this paper we consider the D2D (Device-to-Device) communication taking place between Wireless Sensor Networks (WSN) elements operating in vegetation environments in order to achieve the radio channel characterization ... -
Radio wave propagation and WSN deployment in complex utility tunnel environments
The significant growth of wireless communications systems in the last years has led to the adoption of a wide range of applications not only for the general public but, also, including utilities and administrative authorities. ... -
Spatial characterization of personal RF-EMF exposure in public transportation buses
New services and applications within vehicular environments employ multiple wireless communication systems, within a Heterogeneous Network framework. In this context, evaluation of electromagnetic field impact is compulsory, ... -
Spatial V2X traffic density channel characterization for urban environments
In this work, Vehicle-to-everything (V2X) wireless communications performance is analyzed, in order to account for inherent scenario complexity, in the deployment phase of wireless systems towards the implementation of a ... -
Towards environmental RF-EMF assessment of mmwave high-node density complex heterogeneous environments
The densification of multiple wireless communication systems that coexist nowadays, as well as the 5G new generation cellular systems advent towards the millimeter wave (mmWave) frequency range, give rise to complex ... -
Tuning selection impact on kriging-aided in-building path loss modeling
How do you know you select enough tuning dataset from measurements to guarantee model prediction accuracy? Tuning datasets are often selected based on simple random sampling with predefined rates. Usually, these rates ... -
Validation of 3D simulation tool for radio channel modeling at 60 GHz: a meeting point for empirical and simulation-based models
The radio channel modelling of the millimeter wave bands for the fifth generation of wireless mobile communications, appears as a challenge for both empirical and simulation approaches. In this paper we discuss the use of ...
