Random Access Preamble Design and Detection for 3GPP Narrowband IoT Systems
TL;DR: Simulation results on NPRACH performance including detection rate, false alarm rate, and time-of-arrival estimation accuracy are presented to shed light on the overall potential of NB-IoT systems.
Proceedings ArticleDOI
Performance Evaluation of NB-IoT Coverage
TL;DR: A detailed evaluation of the coverage performance of NBIoT is provided and it is shown that it achieves a coverage enhancement of up to 20 dB when compared with existing LTE technology.
