“…The SDR-based concept of modern radiocommunication systems is widely presented in the literature. Available powerful simulation environments, such as Matlab [16], Simulink [17], or Labview [18], provide toolkits for developing sample testbeds or analyzing the real radio signals. Each of the mentioned tools and methods may be used for didactic purposes, especially if the goal is to analyze the LTE protocol stack and the physical layer.…”

“…In [16,22], the authors proposed a software-defined tool suitable for generating the NB-IoT downlink signal or complete uplink frames. Software described in [22] is based on the open-source LTE-Sim simulator [23].…”

“…Nevertheless, the proposed tool was designed to simulate the entire network operation rather than analyze the particular communication layers. The paper [16] contains a description of a tool for generating the basic downlink synchronization signals only, excluding broadcast channel. Hence, this concept may be treated as the NB-IoT vector signal generator instead of integrated framework.…”

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.

“…Software radio is used in [26] in order to implement and test an IEEE 802.15.4k transceiver for low-energy critical infrastructure monitoring. In the same framework, it is worth citing [27], where the standard LTE-based R13 downlink transmission for IoT has been implemented and tested with SDR and USRP boards. Smartphones with SDR capabilities are considered in [28] to overcome the IoT language barriers, while a low-power basedband processor is designed in [29] to effectively support SDR usage in IoT applications.…”

Internet-of-Things (IoT) represents a breakthrough for the current ICT market. In many IoT applications, sensors and actuators are distributed over very wide areas, sometimes not reached by terrestrial networks. In such scenarios, the satellite plays a significant role. In this paper, a Software-Defined Radio (SDR) -based satellite gateway for Internet-of-Remote-Things (IoRT) is proposed. The use of SDR allows to decrease equipment cost and provides higher flexibility. The proposed architecture has been implemented by using a standalone SDR platform and Commercial Off-The-Shelf (COTS) modules for covering the main terrestrial IoT standards. Extensive proof-of-concept results are presented and discussed. Uplink and downlink tests showed the correct functionality implementation and transmitted signal generation, while the integration tests allowed to assess the reliability of the end-to-end information processing. Reconfigurability tests confirmed the capability of the gateway of dynamically updating in real-time its protocol settings. The overall test results showed the validity of the proposed SDR-based gateway for IoRT applications.INDEX TERMS Internet of Remote Things (IoRT), Satellite Networking, Software-Defined Radio (SDR)
