A method for improving the positioning performance Using Assisted GPS in LoRa Network environment
초록
영어
LoRa, one of the low power wide area (LPWA) communications technologies, enables low cost chip module design and cost savings due to low power, high receiver sensitivity and license-exempt bandwidth. In particular, smart metering and GPS tracking are attempting to construct a network using LoRa technology because the amount of transmission is relatively smaller than the frequency of data transmission. Especially in the field of GPS tracking, location positioning may fail or slow down because of various environmental variables. In this paper, we propose to construct an Assisted GPS system when constructing GPS tracking environment using LoRa to increase the range and speed of positioning in harsh environment.
