Performance Evaluation of LoRa 923 MHz for the Internet of Things

This research focuses on building telecommunication
technology for the Internet of Things, especially on improving
data transmission performance using LoRa, This research uses
LILYGO 923 MHz LoRa32, which is a board that unites ESP32
with LoRa Module and other devices as LED monitors such as
0.96 inch OLED. It also has an interface in the form of a serial
converter to make programming. For cable connection ports,
use micro USB, which is used for power and uploading
programs, This type of LoRa is expected to be able to transmit
images, for the time being only image conversion in the
transmission process. in the test results of the Realibility of
LoRa test with a range of 10 km, the PDR of SF 7 is 50% and
SF 12 is 85%. the RSSI results at a distance of 1000 meters at 3
NLoS are -120 dBm, -90 dBm, and, -78 dBm.
