Remark
● The current sensitivity is tested at an air rate of
2.5kbps.
● Since the material itself has a certain error, a single
LRC component has an error of ±0.1%. However, since a
plurality of LRC components are used in the entire RF
dBm
loop, there is a case where error accumulation occurs,
resulting in a difference in receiving sensitivity of
different modules;
● After increasing the airspeed of the module, the
receiving sensitivity will decrease, resulting in a
decrease in communication distance.
Unit
Remark
● Clear and open, antenna gain is 5dBi, antenna height
is 2.5 meters, and air rate is 2.5kbps;
● Each packet data interval is 2s, 100 packets of data are
sent, each packet of data is 30 bytes, and the packet loss
rate is less than 5% is effective communication distance;
m
● In order to obtain meaningful and reproducible test
results, we choose to conduct tests in sunny and clear
suburbs where almost has no electromagnetic
interference;
● There are obstacles and electromagnetic interference,
and the distance will decrease to varying degrees.
