A method for configuring, in a low-power wide-area wireless network based on LoRa technology, communication parameters for a gateway, termed first gateway, designated by a server of said network to relay information representative of a response to a request, containing data, received by the server, the data originating from a terminal of said network, the information representative of a response being transmitted by the server and intended for the terminal, the method comprises, when it is implemented by the first gateway: acquiring parameters for communication between said first gateway and said terminal; and, configuring the first gateway so as to transmit the information representative of a response using each communication parameter acquired, the data originating from the terminal coming from a frame, termed uplink frame, that is transmitted in multicast mode by the terminal and received by a set of gateways (11A, 11B) comprising at least the first gateway, and the information representative of a response is transmitted by the first gateway to the terminal in a frame, called downlink frame; acquiring the communication parameters by applying a determination procedure comprising: acquiring at least one item of information representative of a distance between the first gateway and at least one second gateway; each item of distance information being determined on the basis of information representative of a geographical location of each second gateway received by the first gateway and having been transmitted in a frame by a second gateway that has measured said item of geographical location information, said second gateway temporarily acting as a terminal to transmit said frame; and, when at least one second gateway is situated at a distance from the first gateway that is shorter than a predefined distance, determining (52, 53, 54) the communication parameters comprising a central frequency, said central frequency being determined by selecting, from among a set of predefined central frequencies, a central frequency having a gap between central frequencies, which are used by each second gateway situated at a distance from the first gateway that is shorter than the predefined distance, larger than a predefined gap. acquiring parameters for communication between said first gateway and said terminal; and, configuring the first gateway so as to transmit the information representative of a response using each communication parameter acquired, the data originating from the terminal coming from a frame, termed uplink frame, that is transmitted in multicast mode by the terminal and received by a set of gateways (11A, 11B) comprising at least the first gateway, and the information representative of a response is transmitted by the first gateway to the terminal in a frame, called downlink frame; acquiring the communication parameters by applying a determination procedure comprising: acquiring at least one item of information representative of a distance between the first gateway and at least one second gateway; each item of distance information being determined on the basis of information representative of a geographical location of each second gateway received by the first gateway and having been transmitted in a frame by a second gateway that has measured said item of geographical location information, said second gateway temporarily acting as a terminal to transmit said frame; and, when at least one second gateway is situated at a distance from the first gateway that is shorter than a predefined distance, determining (52, 53, 54) the communication parameters comprising a central frequency, said central frequency being determined by selecting, from among a set of predefined central frequencies, a central frequency having a gap between central frequencies, which are used by each second gateway situated at a distance from the first gateway that is shorter than the predefined distance, larger than a predefined gap. acquiring at least one item of information representative of a distance between the first gateway and at least one second gateway; each item of distance information being determined on the basis of information representative of a geographical location of each second gateway received by the first gateway and having been transmitted in a frame by a second gateway that has measured said item of geographical location information, said second gateway temporarily acting as a terminal to transmit said frame;
