Summary
This study compares NB-Fi, Sigfox, and LoRaWAN low-power wide-area networks (LPWANs). Sigfox excels with small, unacknowledged data, LoRaWAN with larger data, and NB-Fi with acknowledged small data transmissions.
Area of Science:
- Computer Science
- Electrical Engineering
- Telecommunications
Background:
- Low-Power Wide-Area Networks (LPWANs) are crucial for wireless sensor networks.
- NB-Fi is a new LPWAN technology emerging to compete with established solutions like LoRaWAN and Sigfox.
- Existing literature lacks detailed performance comparisons between these LPWAN technologies.
Purpose of the Study:
- To provide a comprehensive performance analysis and comparison of NB-Fi, Sigfox, and LoRaWAN.
- To evaluate these LPWANs based on empirical performance metrics, not just theoretical specifications.
- To offer practical guidelines for selecting the optimal LPWAN technology based on specific application requirements.
Main Methods:
- Comparative performance evaluation of NB-Fi, Sigfox, and LoRaWAN.
- Analysis of key performance indicators including packet loss rate, packet error rate, and average delay.
- Testing across diverse network scenarios to assess technology performance under varying conditions.
Main Results:
- Sigfox demonstrates superior performance for transmitting small data packets without acknowledgments.
- LoRaWAN proves most reliable for applications requiring the transmission of larger data payloads.
- NB-Fi is best suited for scenarios involving acknowledged transmissions of small data packets.
Conclusions:
- The choice between NB-Fi, Sigfox, and LoRaWAN depends critically on data size, transmission acknowledgment requirements, and desired reliability.
- Empirical performance data provides valuable insights for optimizing LPWAN deployment strategies.
- This research bridges the gap in academic literature regarding direct performance comparisons of leading LPWAN technologies.

A ROC (Receiver Operating Characteristic) plot is a graphical tool used to assess the performance of a binary classification model by illustrating the trade-off between sensitivity (true positive rate) and specificity (false positive rate). By plotting sensitivity against 1 - specificity across various threshold settings, the ROC curve shows how well the model distinguishes between classes, with a curve closer to the top-left corner indicating a more accurate model. The area under the ROC curve...

Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over short...

124
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:
