چکیده
This study modeled the interference between Lora system signal in AS2 frequency band and a non-Lora radio signal. Two devices operate on uplink downlink at of 923.2MHz to send receive data bandwidth 125KHz, 250KHz, 500KHz. The generator device is composed single board computer installed by RPITX application. In addition, there GNU-Radio application monitor transmission levels. Signal quality tests (RSSI, SNR, time-on-air(ToA)) were carried out under line-of-sight (LOS) conditions used reference distances 1m 4m. ToA test shows that greater bandwidth, smaller value, while change distance does not affect ToA. RSSI affects value more significantly than bandwidth. presence an value. SNR testing decreases when occurs.
