“…NB-IoT [21] and Weightless-P [22], for example, encode the signal in low bandwidth (<25 kHz) to reduce the noise level and keep the transceiver design as simple and cheap as possible. Sigfox [23] and Weightless-N [24] further narrow the signal into ultra-narrow bands as narrow as 100 Hz, further reducing the perceived noise.…”

Recent technological innovations allow compact radios to transmit over long distances with minimal energy consumption and could drastically affect the way Internet of Things (IoT) technologies communicate in the near future. By extending the communication range of links, it is indeed possible to reduce the network diameter to a point that each node can communicate with almost every other node in the network directly. This drastically simplifies communication, removing the need of routing, and significantly reduces the overhead of data collection. Long-range low-power wireless technology, however, is still at its infancy, and it is yet unclear (i) whether it is sufficiently reliable to complement existing short-range and cellular technologies and (ii) which radio settings can sustain a high delivery rate while maximizing energy-efficiency. To shed light on this matter, this paper presents an extensive experimental study of the reliability of LoRa , one of the most promising long-range low-power wireless technologies to date. We focus our evaluation on the impact of physical layer settings on the effective data rate and energy efficiency of communications. Our results show that it is often not worth tuning parameters, thereby reducing the data rate in order to maximize the probability of successful reception, especially on links at the edge of their communication range. Furthermore, we study the impact of environmental factors on the performance of LoRa, and show that higher temperatures significantly decrease the received signal strength and may drastically affect packet reception.

-Internet of Things (IoT) marketplace is swiftly expanding as companies across multiple vertical industries recognize the need for connectivity and the potential transformation enabled through connectivity. In short, the Internet of Things refers to the rapidly growing network of connected objects that are able to collect and exchange data using embedded sensors. NB-IOT (Narrowband -Internet of Things), LoRa, and Sigfox wireless technologies have been getting a good deal of attention globally as the market for wireless matures in light of the prospects for billions of connections. The goal of the LoRa Alliance, LoRaWAN adopters, and SigFox is that mobile network operators adopt their technology for IoT deployments over both city and nationwide low power, wide-area networks (LPWANs). But there are some prominent differences between how each technology plans to achieve this goal and which applications the technology is best suited for.

“…In time domain, the overall time slot occupies 0,5 ms. For 3,75 kHz subcarrier spacing, each OFDM symbol is composed of 48 subcarriers, leading to an overall slot time duration of 2 ms. The air interface is optimized to achieve coexixtence with LTE, although not compromising the performance of both technologies: only determined PRB are allowed to be used for NB-IoT cell connection [3], each separated by a 10 kHz guard-band at each side.…”

Abstract-Internet of Things offers a wide spectrum of opportunities for innovative applications designed to improve our life quality. In the energy sector, the developing of smart metering networks allows operators and companies to improve the production efficiency and to offer an enhanced service to customers. 3GPP introduced in Release 13 Narrowband Internet of Things (NB-IoT) as a new cellular technology for providing wide-area coverage for Internet of Things (IoT) and Machine Type Communication (MTC). In this paper, we propose a deployment analysis of a NB-IoT system for smart metering. Estimated number of UE that this system can serve and coverage enhancement considerations with respect to LTE technology are provided.
