“…Since hybrid approaches employ solid reference models based on physical principles and are complemented with measurements to tune up relevant model parameters [4,5], they look promising towards higher accuracy predictions. Such measurement-based modelling approaches have been used in the past with encouraging results [6][7][8][9], taking into consideration that radio measurements are always required even on physical models for validation purposes.…”

An accuracy evaluation analysis of a novel in-building measurement-based path loss prediction narrowband model is presented here, comparing the performance of Krigingaided shadowing prediction against the most traditional assumption of slow fading as a random variable and a classical estimation derived from linear interpolation. Extensive radio measurements were employed using distinct samples to calibrate (tuning dataset) and validate (testing dataset) the model. Path loss predictions are made over the testing dataset locations to compare it against the measured values, thus obtaining an error in the prediction from the difference between measurements and predictions. The results in the seven buildings evaluated show the potential of Kriging-aided channel modelling with a higher level of confidence than other modelling approaches compared hereafter.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.

“…Conventional beam steering, such as a phased array, reflectarray, and mechanical beam steering, is commonly implemented in a wide field of applications over the years 1‐5 . Recently, considerable research interests have been dedicated to millimeter‐wave (mm‐wave) communication systems in which a new generation of beam steering antennas based on Luneburg lens (LL) technology are dominated research areas in mm‐wave frequencies 6‐8 . Luneburg lens as a gradient index lens originally referring to a dielectric lens of a spherical or cylindrical shape, which possesses rotational symmetry and focusing properties and enables beam‐scanning capabilities among multiple feed elements 9…”

In this article, we propose a new design of a multibeam cylindrical Luneburg lens antenna designed in the 28 GHz band. The proposed antenna is based on the parallel plate waveguide technique, in which the plates are separated by a fixed spacing and a homogenous dielectric material is applied between the plates. The most intuitive advantage of the proposed lens against the previous ones is the simplicity of the lens profile and volume, which is essential for the whole design and manufacturing processes for high‐frequency applications. In addition, it provides a cost‐effective and simple mechanical assembly. To reduce the losses associated with the feed elements, the lens is excited by an array of simple and compact integrated waveguide elements. The measured results show that the proposed antenna achieves a maximum gain of 17.73 dB and a maximum beam steering angle of 57.7° in the azimuth plane. Furthermore, the measured gain of the antenna varies by only 1 dB over the entire beam steering rang and the measured side lobe level of the antenna is less than −12.2 dB.

“…A study [11] conducted channel measurements at Boise Airport in both LOS and NLOS scenarios and presented a large scale fading channel model of 60 GHz. Another study [12] focused on LOS mmWave propagation measurement and modeling also took place in Boise Airport. To the best of authors' knowledge, only one study [13] exists on airport mmWave propagation characterization at 28 GHz in an indoor scenario.…”

In the upcoming 5G communication, the millimeter wave (mmWave) technology will play an important role due to its large bandwidth and high data rate. However, mmWave frequencies have higher free-space path loss (FSPL) in line-ofsight (LOS) propagation compared to the currently used sub-6 GHz frequencies. What is more, in non-line-of-sight (NLOS) propagation, the attenuation of mmWave is larger compared to the lower frequencies, which can seriously degrade the performance. It is therefore necessary to investigate mmWave propagation characteristics for a given deployment scenario to understand coverage and rate performance for that environment. In this paper, we focus on 28 GHz wideband mmWave signal propagation characteristics at Johnston Regional Airport (JNX), a local airport near Raleigh, NC. To collect data, we use an NI PXI based channel sounder at 28 GHz for indoor, outdoor, and indoor-to-outdoor scenarios. Results on LOS propagation, reflection, penetration, signal coverage, and multi-path components (MPCs) show a lower indoor FSPL, a richer scattering, and a better coverage compared to outdoor. We also observe high indoor-to-outdoor propagation losses.
