“…In fact, the RC is able to provide very rich multipath propagation environment, capable to stress the connection between the BS and UE(s) [11,20,21]. A large variety of situations can be reproduced inside the RC [11,14,15] by tuning RC parameters like the quality factor, the power delay profile and the Rician K-factor by adding absorbing material inside it [16,22,23].…”

“…Results carried out in this measurements campaign will be preparatory for upcoming activities where RIS(s) will be tested. This paper presents a preliminary experimental activity on the 5G base station (BS) functionalities, by carrying out over-the-air tests inside a reverberation chamber (RC) [11][12][13][14][15], preparatory for future tests when the RIS will be included in the experimental set-up. By using the RC we are able to reproduce complex propagation conditions both for the BS and UE.…”

The performance of a real fifth generation base station was studied by using a reverberation chamber as a real life propagating environment. Preliminary tests were conducted in order to define 5G base station operation conditions at mm-wave and emulated scenarios where reconfigurable intelligent surface(s) (RISs) will successively be tested. Measurements campaign was carried out under the H2020 European project RISE-6G and a collaboration program between TIM S.p.A.,

“…Reference signal received power (RSRP) is an indicator that shows the signal strength of the eNodeB received by user equipment (UE) [18]. The RSRP value is used to show the quality of network coverage in an area, the greater the RSRP value, the better the quality of the signal emitted by the transmitter.…”

<span>The increasing demand for telecommunication services causes data traffic density. Therefore, in this research, the long-term evolution (LTE) network expansion was carried out using a choice of frequency bands of 700 MHz, 2100 MHz, and 2300 MHz. The analysis was carried out from the technical and economic aspects. Frequency band recommendations were obtained using the simple multi-attribute rating technique (SMART) method. This research was conducted using a case study of Semarang City. Based on the simulation results, the average of reference signal receive power (RSRP) values for frequency 700 MHz and 2300 MHz is in the very good range, while the frequency of 2100 MHz is in the good range. The signal to interference noise ratio (SINR) values for the three frequencies are in the normal category and the throughput values are in the very good category. The techno-economic calculations of the three frequencies, namely the value of internal rate of return (IRR), net present value (NPV), and payback period are included in the business category that is feasible to do. Based on the ranking results, the 700 MHz frequency is the most superior, both in terms of technical and economic aspects.</span>

“…We believe the usage of RIS in BLE framework can increase the signal quality, PER performance and also increase the overall lifetime of already energy-constraint IoT devices. In this work, we arranged master and slave BLE nodes in NLOS in a reverberant metal enclosure, an environment that has been tackled by other investigators in wireless communication (Gagliardi et al, 2015;Micheli et al, 2016;Barazzetta et al, 2017;Primiani et al, 2020;Micheli et al, 2021), as shown in Figure 1. We have optimized the PER performance using RIS of all the BLE PHY modes.…”

Reconfigurable intelligent surface (RIS) technology is at the forefront for its transformative role in future wireless communication systems such as wireless local area networks (WLAN), sixth-generation (6G) communication, and internet-of-things (IoT). This paper presents RIS-assisted Bluetooth low energy (BLE) communication links in neighbor discovery mode. We optimized the packet error rate (PER) performance of the BLE communication link in a highly reflecting metal enclosure environment. We used one RIS for the PER optimization of four BLE physical (PHY) modes. Then, we used two RISs simultaneously in a distributed and centralized manner to further optimize the PER of all BLE PHY modes. We found PER optimization using two RISs is better than the PER optimization using one RIS. Additionally, PER optimization using a centralized arrangement of RISs outperformed PER optimization using distributed arrangement. We found the coded BLE modes i.e., LE500K and LE125K show lower PER than the uncoded counterpart i.e., LE1M and LE2M. This is because uncoded BLE PHY modes have higher data rates than the coded BLE PHY modes. Because of additional channel power gains introduced by RIS-based passive beamforming, the PER of coded and uncoded BLE PHY modes is further reduced.
