● It ensures that the performance of the module can reach
the standard if it works in recommended operating
frequency.
● It is recommended to avoid the crowded frequencies, such
as 433.0MHz, 868.0MHz, 915MHz and other integer
frequencies.

● The external antenna used is of 5dBi gain and vertical
polarization;
● 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 reproduceable results,
we conducted the tests under in clear weather with little
electromagnetic interference at suburb areas;
● Distance may be shorter with interference or obstacles.
