Millimeter-Wave (mmW) communication systems, capable of achieving high data rates
thanks to the large bandwidth available in this frequency range, are a promising 5G …

The proliferation of location-based services highlights the need to develop an accurate
indoor localization solution. The global navigation satellite system does not deliver good …

These days, location-based services, or LBS, are used for various consumer applications,
including indoor localization. Due to the ease with which Wi-Fi can be accessed in various …

Knowledge of the properties of millimeter-wave (mmWave) propagation channels is
important for the development and deployment of 5G and 6G wireless systems. This paper …

The advent of bandwidth–demanding mobile applications and services has led to a massive
explosion of the network data traffic. In order to alleviate this issue, millimeter–Wave …

This paper investigates the polarization behavior of the propagation channel in urban
macrocell environments at 2 GHz. The study is based on a dual polarized single-input …
