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.
