On the NB-IoT Used for Aids to Navigation
2019 International Conference on Information and Communication Technology Convergence (ICTC), 2019We implemented NB- IoT base station and terminal based on the 3GPP Release 13. Our NB- IoT system has been applied to the Smart Factory and the railroad monitoring system. In this paper, we introduce the AtoN NB-IoT system which applied the NB-IoT technology to the AtoN facility.

Interference Analysis of Guardband NB-IoT System
2018 International Conference on Information and Communication Technology Convergence (ICTC), 2018Massive connectivity is one of the major goals of 5G mobile communications. The NB-IoT system achieves this goal using only a very narrow bandwidth. The NB-IoT system can also work together without affecting existing LTE systems. In this paper, we analyze the interferences of guardband NB-IoT system from the LTE system when they coexist.

Optimization of Random Access Channel in NB-IoT
IEEE Internet of Things Journal, 2018Narrowband Internet of Things is a new access technology introduced by 3GPP. This paper presents an analytical model to estimate the access success probability and average access delay of the random access channels by considering maximum number of preamble transmissions, size of backoff windows, and number of subcarriers in each coverage enhancement ...

NB-IoT Random Access Procedure Analysis
2018 IEEE 10th Latin-American Conference on Communications (LATINCOM), 2018Narrowband Internet of Things (NB-IoT) is a cellular technology that will provide connection for a massive number of low-cost and low-power devices. This work describes the analysis of delay the NB-IoT, calculating the probability of success in the random access procedure, as well the average delay and normalized flow rate for different parameter ...

A Theoretical Model for Planning NB-IoT Networks
2019 International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob), 2019The growth of Internet of Things (IoT) technologies has triggered the development of low-cost solutions characterised by low energy consumption and low complexity. To interconnect these devices, some wireless communications technologies including IEEE 802.11 and IEEE 802.15.4 have been used due to their deployment and management simplicity and high ...
