The utility model discloses a promote device of loRa private agreement gateway sensitivity of reception, after loRa gateway equipment and terminal node equipment set up wireless communication, the gateway configures and acquires the RSSI value to the terminal according to predetermined radio frequency parameter setting table, sets for and preserves the parameter according to best RSSI value. And the RSSI value is acquired through a receiving through channel. The utility model discloses a set for optimum radio frequency configuration parameter to combine the RSSI value that tests to, carry out selective enlarging, decay and filtering to received signal through preceding stage LNA, attenuator and wave filter, thereby reduced the noise figure of loRa gateway receiver and reach the purpose that improves the reception sensitivity. |
