Abstract
Internet of Things (IoT) is a paradigm for connecting any devices onto internet. The IoT applications can be implemented in IoT, for example, e-health, smart logistics, smart transportations, and smart homes. In smart logistics, objects and deliveries location need to be updated in real time, so they can be tracked easily. Asset tracking employs Global Positioning System (GPS) and commonly General Packet Radio Service (GPRS) connections to send telemetry data to database server. Narrowband-IoT (NB-IoT), a new cellular standard that is optimized for Low Power Wide Area Network (LPWAN) applications, such as asset tracking. Compared to GPRS, it has smaller uplink transmit power and has decent uplink speed. In this paper, NB-IoT was utilized for asset tracking. The performance of NB-IoT was compared to GPRS, specially for these parameters: latency, throughput, packet loss, and power usage. The result obtained shows that, NB-IoT has average latency around 1.4 seconds, with packet loss (UDP) 44% compared to GPRS 68%. NB-IoT has better power consumption during data transmission against GPRS (0.405 W vs 0.737 W) even though both of them have similar uplink throughput (around 350 B/s). From this test result, this new cellular standard is appropriate in Asset Tracking application.
