“…Pada Penelitian [4]- [7], telah diteliti rugi-rugi lintasan dari luar ke dalam dengan mengaplikasikan frekuensi di luar dari 1.8 GHz dan 2.1 GHz. Pada Penelitian [5], frekuensi 1.8 GHz juga diaplikasikan, namun penelitian tersebut tidak mengaplikasikan model rugi-rugi lintasan dan hanya bertujuan mengukur rugi-rugi yang disebabkan oleh penyerapan dinding.…”

Rugi-rugi lintasan gelombang radio menjadi salah satu parameter penting untuk menjamin kelancaran komunikasi nirkabel. Saat ini, penggunaan komunikasi nirkabel untuk mendukung proses pembelajaran di ruang perkuliahan telah banyak diaplikasikan. Namun, rugi-rugi lintasan gelombang radio di ruang perkuliahan mengalami peningkatan jika gelombang radio berpropagasi dari luar gedung. Hal tersebut disebabkan gelombang radio mengalami rugi-rugi lintasan secara dua tahap, yaitu di luar gedung dan di dalam gedung. Berdasarkan hal tersebut, penelitian ini bertujuan mengukur dan menganalisis pengaruh koridor di gedung kampus terhadap rugi-rugi lintasan gelombang radio di ruang perkuliahan. Sebuah antena pemancar di luar gedung kampus milik salah satu penyedia jasa layanan telekomunikasi digunakan pada penelitian ini. Selanjutnya metode drive test digunakan untuk mengukur rugi-rugi lintasan gelombang radio di ruang perkuliahan. Tiga model rugi-rugi lintasan yang kontemporer juga digunakan untuk memprediksi rugi-rugi lintasan gelombang radio. Ketiga model tersebut adalah Model Winner+, Model COST231, dan Model 3GPP. Berdasarkan hasil penelitian, diketahui bahwa koridor di dalam gedung mampu menurunkan rugi-rugi lintasan gelombang radio. Selain itu, diketahui juga bahwa Model COST231 lebih akurat memprediksi rugi-rugi lintasan gelombang radio dari luar ke dalam gedung kampus daripada model rugi-rugi lintasan lain yang digunakan

“…T Here are several studies in the literature on different frequency bands as alternatives for the new fifth generation (5G) mobile network [1]- [3]. The 5G will cover the frequency spectrum from around 500 MHz to 100 GHz, with emphasis on frequency bands below 6 GHz or so-called Sub-6 GHz bands [3].…”

This letter presents an analysis of the radio propagation channel based on measurements at the 3.5 GHz frequency. The measurement campaigns were carried out inside the Valde-Cans airport using line-of-sight (LOS) transmissions. First, the channel small-scale dispersion parameters were extracted through channel probing and the results are similar to those obtained by ITU-R P.1238 for the bands below 15 GHz considering commercial indoor environments as well as for those using the 3.5 GHz band in outdoor environments utilizing WiMax OFDM-256 signals. Then, the floating-intercept (FI) and close-in (CI) models are applied and analyzed to evaluate the received signal behavior for co-polarized and cross polarized antennas. The results show that the CI path loss exponent values are close to the free space propagation loss model, while the FI model provides a lower root mean square error (RMSE) to the measured data. The results show that the FI and CI models are suitable for large-scale indoor propagation loss modeling for 5G networks with a frequency of 3.5 GHz.

“…There are a few works performing outdoor-to-indoor measurements to characterize the communication channel at around 3.5 GHz in different scenarios such as urban microcell [17], urban macrocell [18], non-line of sight [19], residential buildings [20], multiple-input-multipleoutput (MIMO) in an office building [21], dense urban [22], and university buildings [23,24].…”

Understanding radio propagation characteristics and developing channel models is fundamental to building and operating wireless communication systems. Among others uses, channel characterization and modeling can be used for coverage and performance analysis and prediction. Within this context, this paper describes a comprehensive dataset of channel measurements performed to analyze outdoor-to-indoor propagation characteristics in the mid-band spectrum identified for the operation of 5th Generation (5G) cellular systems. Previous efforts to analyze outdoor-to-indoor propagation characteristics in this band were made by using measurements collected on dedicated, mostly single-link setups. Hence, measurements performed on deployed and operational 5G networks still lack in the literature. To fill this gap, this paper presents a dataset of measurements performed over commercial 5G networks. In particular, the dataset includes measurements of channel power delay profiles from two 5G networks in Band n78, i.e., 3.3–3.8 GHz. Such measurements were collected at multiple locations in a large office building in the city of Rome, Italy by using the Rohde & Schwarz (R&S) TSMA6 network scanner during several weeks in 2020 and 2021. A primary goal of the dataset is to provide an opportunity for researchers to investigate a large set of 5G channel measurements, aiming at analyzing the corresponding propagation characteristics toward the definition and refinement of empirical channel propagation models.
