Abstract

Today we are living in a society where an ever increasing number of devices or things are being connected to the Internet. Many of these devices are battery powered with the long term success of the business case justifying the deployment of these devices, dependent upon the ability of these devices to operate autonomously for extended periods without intervention to replace batteries. Utility companies delivering water and gas are seeking 10 year plus lifetimes from devices without a truck roll to replace batteries. The current industry understanding of the 5G technologies, NB-IoT and eMTC, is NB-IoT offers lower power consumption but there is little evidence for that belief. This paper uses standard load models to systematically investigate the energy demands of the two different radio access technologies under realistic usage patterns. The paper also investigates some key factors influencing energy consumption and whether a device could operate from an ideal 5 Wh battery for 10 years. In contributing to the field of knowledge in this area, we set out to compare 3GPP IoT radio access technologies using techniques aligned with existing 3GPP energy consumption evaluation methodologies. In adopting that approach, contrary to established industry opinions and messaging, we found when operating as an eMTC device, our radio module consumes less power than when it was operating as an NB-IoT device. Irrespective of it’s operating mode, our radio module was unable to achieve a 10 year battery life from an ideal 5 Wh battery using a typical IoT traffic model. Most interestingly, we observed minimal change in energy consumption whether the payload size was 1 byte or 1400 bytes.

Author

Tamentsev, Viacheslav and Tamentsev, Viacheslav

Abstract

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.

Abstract

In the Internet of things (IoT), many applications will require low-power and low-cost to achieve long lifetime and scale (respectively). These types of applications are referred to as massive IoT, as opposed to critical IoT, which emphasizes ultra-high reliability and availability and low latency. One type of network catering to massive IoT applications are Low-Power Wide Area Networks (LPWANs), and presently, many LPWAN standards are trying to assert their role in the IoT ecosystem. This thesis explores LPWANs from both technical and non-technical perspectives to ascertain their use-case versatility and influence on the future telecommunications’ landscape. With respect to spectrum, the studied LPWANs may be categorized as unlicensed LPWAN or licensed LPWAN. The prior category typically refers to proprietary solutions and in this thesis are represented by SigFox and LoRaWAN. The latter group includes EC-GSM-IoT, eMTC, and NB-IoT and can be considered synonymous with cellular LPWAN because they are designed to be integrated into existing cellular infrastructures. The results indicate that all of the different types of explored LPWANs support applications without strict downlink, payload size, and latency requirements. For use cases without these specific demands (typically sensors, meters, tracking, etc.), it is not a question of whether or not a network fulfills the requirements, but rather how flexible the requirements are. As a result the choice of network will be determined by non-technical aspects and a cost versus functionality trade-off where unlicensed LPWAN is typically cheaper. Hence, both categories of LPWANs offer a unique value proposition; therefore, they can be considered complementary. This notion is reinforced when looking at non-technical aspects such as ecosystem, regulation, network ownership and control, and network coordination, which differ quite significantly. Furthermore, unlicensed LPWANs are likely to be the vanguard of a new type of competitor offering the core service of connectivity. Inom Internet of Things (IoT) kommer många applikationer att kräva låg effekt och låg kostnad för att uppnå en lång livstid och skala. Dessa typer av applikationer refereras till som massiv IoT, vilket står i motsats till kritisk IoT som kräver ultrahög tillförlitlighet och tillgänglighet och låg fördröjning. En typ av nätverk som ämnar tillgodose kraven av massiv IoT är Low-Power Wide Area Networks (LPWANs), och idag försöker många av dessa hävda sig inom IoT ekosystemet. Detta examensarbete undersöker LPWANs from ett teknisk och icke-tekniskt perspektiv för att utröna deras mångsidighet och påverkan på det framtida telekomlandskapet. Med avseende på spektrum kan de i detta examensarbete undersökta nätverken kategoriseras som olicensierat LPWAN eller licensierat LPWAN. Den tidigare hänvisar typiskt till proprietära lösningar och representeras i detta arbete av SigFox och LoRaWAN. Den senare kategorin består av EC-GSM-IoT, eMTC, och NB-IoT och kan betraktas som synonymt med mobil LPWAN eftersom de designade för att bli integrerade i existerande mobila nätverk. Resultaten indikerar att alla nätverk stödjer applikationer utan strikta krav när det gäller nedlänkens funktionalitet, mängden data per meddelande, och fördröjning. För applikationer utan dessa specifika krav (typiskt sensorer, mätare, spårning, etc.) är det inte en fråga om huruvida ett nätverk uppfyller kraven eller ej, utan snarare hur flexibla kraven är. Därför kommer valet av nätverk att bestämmas av icke-tekniska aspekter och en avvägning mellan kostnad och funktionalitet vari olicensierat LPWAN är vanligtvis billigare. Därmed erbjuder båda kategorier av nätverk en unik värde proposition och kan därför betraktas som komplementerande. Denna föreställning är förstärkt av att nätverken skiljer sig signifikant när det gäller deras icke-tekniska aspekter såsom ekosystem, reglering, ägandeskap och kontroll, och nätverks koordinering. Dessutom är olicensierade LPWANs troligen är förtruppen av en ny typ av konkurrent som erbjuder den grundläggande servicen av konnektivitet.

Abstract

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., 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.

Abstract

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., 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.

Abstract

A triple-mode RF system on a chip (SoC) is reported which supports cellular Internet of Things (IoT) standards eMTC, NB-IoT, and EC-GSM, as well as 2G fallback. In the eMTC mode, the SoC achieves best-in-class performance for reference sensitivity (−112.3 dBm), coverage extension mode A (−128.5 dBm) and B (−136.8 dBm), respectively. A very efficient RTC, combined with dynamic power management of unused clocks and idle blocks, also leads to excellent performance in cellular IoT power-saving modes, such as extended discontinuous reception and power-saving mode., IEEE Solid-State Circuits Letters, 3, ISSN:2573-9603
