In this paper, the channel measurements for 5th generation mobile networks (5G) potential spectrum at 3.35 GHz, 4.9 GHz and 5.4 GHz have been performed in the urban macro cell scenarios in China. The measured cases include line-of-sight (LOS) and non-line-of-sight (NLOS) propagation. After acquiring the channel impulse response from the measurement data, the empirical log-distance path loss models are derived. Free-space and ITU-R models are analysed as references. To explore the relation between path loss and carrier frequency, we revise the proposed path loss models by introducing the frequency dependence coefficient (FDC). Furthermore, when FDC is applied, a more accurate description of path loss differences among three frequencies can be obtained in NLOS case. Measurements can be implemented in more scenarios to acquire optimised channel models in the future.

Wireless connectivity has been realized for multiple environments and different frequency bands. However, little research exists about mmWave communication in industrial environments. This paper presents the 60 GHz double-directional radio channel for mmWave communication in a ship hull for Line-of-Sight (LOS) and non-Line-of-Sight (NLOS) conditions. We performed channel measurements using the Terragraph channel sounder at different locations in the ship hull and fitted LOS path loss to a one-slope path loss model. Path loss and root-mean-square delay spread of the LOS path is compared to the reflected path with lowest path loss. NLOS communication via this first-order reflected path is modeled by calculating the path distance and determining the reflection loss. The reflection losses have a considerable contribution to the signal attenuation of the reflected path. The channel models are implemented in an indoor coverage prediction tool, which was extended with a ray launching algorithm and validated by comparison with an analytical electromagnetic solver. The results show that the mmWave radio channel allows high-throughput communication within a ship hull compartment, even when no LOS path between the transmitter and receiver is present.
