Analysis of LTE and NB-IoT coexistence
2017 International Conference on Information and Communication Technology Convergence (ICTC), 2017Massive connectivity is one of the major goals of 5G mobile communications. NB-IoT systems are emerging as a way to achieve this goal. In this paper, we analyze the interferences between the LTE system and the NB-IoT system when they coexist.

NB-IoT system for M2M communication
2016 IEEE Wireless Communications and Networking Conference, 2016In 3GPP, a narrowband system based on Long Term Evolution (LTE) is being introduced to support the Internet of Things. This system, named Narrowband Internet of Things (NB-IoT), can be deployed in three different operation modes - (1) stand-alone as a dedicated carrier, (2) in-band within the occupied bandwidth of a wideband LTE carrier, and (3) within

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 ...
