Tool/software:
1. The 15.4 protocol stack we use, the RF parameters are generated according to the studio software, and the transmit power is 13dBm.
2. In the previous test, in the open distance, the RSSI can be measured to -98dbm, which corresponds to the distance at this time is about 600m.
Now we test, open test, RSSI to -85dbm below, can not be received, at this time the distance is only 300m.
It is evident that the reception sensitivity has deteriorated.
What causes the deterioration of reception sensitivity? How do we solve the problem of low reception sensitivity?
