“…The NB-Iot network is chosen as the main network option, due to the fact that it is designed specifically for IoT applications and it is lightweight, low-powered and performs better on low data rates. It is observed that the NB-IoT network is able to provide connectivity to devices with a received signal strength indicator (RSSI) value as low as −105 dBm as compared to −95 dBm of long-term evolution (LTE) [22]. In order to test the range of the connectivity of the NB-IoT SIM7020 module that is used on the smart tag, measurements of the signal's strength, known as the RSSI, are acquired.…”

The building materials of Cultural Heritage monuments are subjected to continuous degradation throughout the years, mainly due to their exposure to harsh and unexpected weather phenomena related to Climate Change. The specific climatic conditions at their vicinity, especially when there are local peculiarities such as onshore breeze, are of crucial importance for studying the deterioration rate and the identification of proper mitigation actions. Generalized models that are based on climate data can provide an insight on the deterioration but fail to offer a deeper understanding of this phenomenon. To this end, in the context of the EU-funded HYPERION project a distributed smart sensor network will be deployed at the Cultural Heritage monuments in four study areas as the solution to this problem. The developed system, which is demonstrated in this paper, includes smart IoT devices, called Smart Tags, designed to provide environmental measurements close to monuments, a middle-ware to facilitate the communication and a visualization platform where the collected information is presented. Last but not least, special focus is given to the device’s NB-IoT connectivity and its power efficiency by conducting various tests and extract useful conclusions.

“…Coverage enhancement defined in the NB-IoT specification gives 20 dB higher maximal coupling loss with respect to the Global System for Mobile Communication (GSM) packet data service [9,10]. Nevertheless, apart from abovementioned features, there are other advantages of the NB-IoT usage, e.g., energy efficiency or an easy integration with the preexisting cellular networks.…”

In the radiocommunication area, we may observe a rapid growth of new technology, such as 5G. Moreover, all the newly introduced radio interfaces, e.g., narrowband Internet of Things (NB-IoT), are strongly dependent on the software. Hence, the radiocommunication software development and optimization, as well as the 3GPP technical specification, should be introduced at the academic level of education. In this paper, a software-defined NB-IoT uplink framework in the field of design is presented, as well as its realization and potential use cases. The framework may be used as an academic tool for developing, investigating, and optimizing the digital transmitter paths. The proposed realization is focused on the key elements in the physical layer of the NB-IoT interface used in the sensor devices. Furthermore, the paper also highlights the need of the data processing optimization to minimize the power consumption and usage of the resources of the NB-IoT node during transmitting gathered telemetric data.

“…On the other hand, not enough hardware can result in dead zones and a failed solution. In addition, as the spaces we wish to use indoor positioning and asset tracking on expands, the complexity, security vulnerability and cost increases as well [9]. What may work well in a small 400 square foot area can cost dramatically different compared to a 16,400 square foot warehouse.…”

Nowadays, our society can be considered as a "connected society" thanks to a heterogeneous network and the growth of mobile technologies. This growth has meant new devices are now supporting Internet of Things (IoT) architecture. Consequently, a new look at the current design of wireless communication systems is needed. Smart mobility concerns the massive movement of people and requires a complex infra-structure that produces a lot of data, creating new interesting challenges in terms of network management and data processing. In this paper, we address classic generations of mobile technology until the latest 5G implementation and its alternatives. This analysis is contextualized for the problem of smart mobility services and people-centric services for the internet of things that have a wide range of application scenarios within smart cities.
