Femtocell networks have emerged as a key technology in residential, office building or
hotspot deployments that can significantly fulfill high data demands in order to offload indoor …

This paper presents the verification of indoor propagation channel simulations based on an
intelligent ray launching algorithm (IRLA) in the Ka-band of the millimeter-wave (mmWave) …

This paper presents a modified ray launching model based on the Intelligent Ray Launching
Algorithm (IRLA) that was previously proposed. IRLA is a 3D discrete ray launching model …

Three-dimensional (3D) multi-input-multi-output (MIMO) is one of the enabling technologies
for next-generation mobile communication. As the elevation angle in the 3D MIMO channel …

Ray-based methods such as ray tracing and ray launching have been increasingly used in
radio wave propagation modelling. Ray tracing is used for point-to-point multipath prediction …

For 5G/6G system simulations and radio planning the availability of both accurate and run-
time efficient channel predictors is required. This paper presents a 3D ray tracing channel …

A new model used to compute the outdoor to indoor signal strength emitted from an outdoor
base station is presented. This model is based on the combination of 2 existing models …

Indoor propagation models attract much interest these days because of their importance in
the applications of 3G/4G network planning and optimisation. The accuracy and running …

The millimeter wave spectrum is widely studied as one of the most important resources for
the IMT (International Mobile Telecommunication) system towards to the 5G for the large …
