●
The external antenna used is of 2.5dBi gain and vertical polarization.
The height is 2.5 meters;
●
The interval between each data packet is 2s, sending 100 packets
with 30 bytes in each packet, the range at data lose rate of lower than
5% is valid range;
●
In order to obtain meaningful and reproducible results, we
conducted the tests under in clear weather with little electromagnetic
interference at suburb areas；
● Distance may be shorter with interference or obstacles.
