Implementation of LTE Cat-M Technology for Smart Measurement Scenarios
Tamentsev, Viacheslav
The requirements introduced in Directive 2019/944 of the European Parliament for smart metering scenarios, which differ from the ones defined in ITU-R M.2410, accelerated the integration of cellular technologies for the Internet of Things (IoT). With the release of cellular IoT (CIoT) technologies in the Czech Republic, recently LTE Cat-M, the focus shifts towards evaluating the performance in massive scenarios where thousands of devices are connected to one base station. This paper examines the feasibility of implementing LTE Cat-M communication technology in Network Simulator 3 (NS-3) to cover massive Machine-Type Communication (mMTC). The paper analyzes the capabilities of cellular modules within the selected simulation tool Networks Simulator 3 (NS-3), including the LENA module. First, simulation scenarios are created to validate and benchmark the performance of legacy LTE/LTE-A networks with attention to (mMTC) scenarios. The key output is the determination that the 4G networks are unsuitable for these scenarios. Further, based on the obtained data, the initial discussion on the requested implementation to support the LTE Cat-M in the NS-3 is provided, pointing out the exact changes associated with the physical layer.

Tamentsev, Viacheslav ; Le, Dinh Thao (referee) ; Mašek, Pavel (advisor)
The Diploma work examines the feasibility of implementing Long-Term Evolution for Machine-Type Communications (LTE Cat-M) communication technology in Network Simulator-3 (NS-3) to provide massive Machine-Type Communication (mMTC). The paper analyzes the capabilities of cellular communication modules in the selected NS-3 simulation tool, including the LTE/EPC Network Simulator (LENA) module. In the theoretical part, it considers Low-Power Wide Area (LPWA) global networking technologies and their applications, including key aspects of the IoT Internet and Machine-to-Machine (M2M) communications. Special attention is given to analyzing the most common technologies in LPWA networks, such as Sigfox, Low-Power Wide Area Network (LoRaWAN), Narrowband Internet of Things (NB-IoT) and Long Term Evolution for Machines (LTE Cat-M). In the practical part, simulation scenarios are created to testing and comparing the performance of legacy LTE/LTE-A networks with focus on mMTC scenarios. The result is the determination that 4G networks are not suitable for these scenarios. Therefore, for such scenarios, the LTE/EPC Network Simulato Narrowband (LENA-NB) module is being used for modifications to the LENA module to meet LTE Cat-M requirements.

Implementation of IoT communication technologies in NS-3 simulation tool
Rehberger, Marek ; Mašek, Pavel (referee) ; Juráň, Radovan (advisor)
The bachelor thesis deals in its theoretical part with LPWA communication technologies in the licensed frequency spectrum, specific technologies LTE Cat-M1 and NB-IoT. The theoretical part summarizes the terms concerning to LPWAN (Low Power Wide Area Network), licensed and unlicensed technologies, SmartGrids, NB-IoT and LTE Cat-M1. The use of LPWA technologies in the field of SmartGrids is described and the idea of Smart Metering in buildings is used in the work. Subsequently, in the practical part for the LTE Cat-M1 technology, the implementation of communication scenarios for data transmission within SmartGrids is performed using the tools Network Simulator 3 (NS-3) and the LENA module.
