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.

Implementace technologie LTE Cat-M pro scénáře chytrého měření
Tamentsev, Viacheslav ; Le, Dinh Thao (oponent) ; Mašek, Pavel (vedoucí práce)
V diplomové práci je zkoumána možnost implementace komunikační technologie Long-Term Evolution for Machine-Type Communications (LTE Cat-M) v Network Simulatoru-3 (NS-3) pro zajištění massive Machine-Type Communications (mMTC). Článek analyzuje možnosti modulů celulární komunikace ve vybraném simulačním nástroji NS-3, včetně modulu LTE/EPC Network Simulator (LENA). V teoretické části jsou diskutovány globální síťové technologie rozlehlých sítí Low-Power Wide Area (LPWA) a jejich aplikace, včetně klíčových aspektů internetu věcí a komunikace Machine-to-Machine (M2M). Zvláštní pozornost je věnována analýze nejběžnějších technologií v sítích LPWA, jako jsou Sigfox, Low-Power Wide Area Network (LoRaWAN), Narrowband Internet of Things(NB-IoT) a Long Term Evolution for Machines (LTE Cat-M). V praktické části jsou vytvořeny simulační scénáře pro testování a porovnání výkonnosti starších sítí LTE/LTE-A se zaměřením na scénáře mMTC. Výsledkem je konstatování, že sítě 4G nejsou pro tyto scénáře vhodné. Proto je pro realizaci takových scénářů používán modul LTE/EPC Network Simulato Narrowband (LENA-NB) pro modifikace modulu LENA splňující požadavky LTE Cat-M.

Implementation of the LTE Cat-M1 Communication Technology Using the Network Simulator 3
Maslák, Roman ; Možný, Radek (oponent) ; Mašek, Pavel (vedoucí práce)
The Diploma work deals with the implementation of LTE Cat-M technology in the simulation tool Network Simulator 3 (NS-3). The work describe LPWA technologies and their use cases. In first are described the main parts of the Internet of Things (IoT) and Machine-to-Machine (M2M) communication. Subsequently are described and defined the most used technologies in LPWA networks. Technologies which are used in the LPWA networks are Sigfox, LoRaWAN, Narrowband IoT (NB-IoT) and Long Term Evolution for Machines (LTE Cat-M), where LTE Cat-M technology is described in more details. Simulations are simulated in simulation tool NS-3 and use LENA module. In NS 3 tool are simulated Simulations, which give us informations of Network state according to different Network set up. At the end are done changes of Radio Resource Control (RRC) states in NS-3 tool. These changes are required for correct implementation LTE Cat-M technology in NS-3 tool. Then we are able to simulate simulations, which meet to definition of LTE Cat-M technology.
