A device included in a communication system that includes a LoRa endpoint and a LoRa server. Each LoRa frame exchanged between the endpoint and the server has to pass through a meter and a data concentrator included in a first powerline communication network of a system for the automatic management of readings from meters. The meters are attached to at least one data concentrator via the first network. At least one of the meters implements a LoRa gateway that has a communication interface enabling it to exchange LoRa frames with the endpoint. The device is connected to each data concentrator by a second network and to the server by a third network. Each LoRa frame exchanged between the endpoint and the server (1) passes through the device and (2) is encapsulated in a frame according to a frame format that the server will exchange with a LoRa gateway.
A device for exchanging first frames, referred to as LPWAN frames, between an endpoint and a server, said endpoint being configured to exchange LPWAN frames with at least one gateway, referred to as an LPWAN gateway, by means of a first low power long range wireless network, and the server being configured to exchange LPWAN frames with LPWAN gateways, each LPWAN frame exchanged between the endpoint and the server having to pass through at least one meter and a data concentrator included in a second powerline communication network and forming a system for the automatic management of readings from a plurality of electricity meters, referred to as an AMM system, at least one meter in said AMM system implementing an LPWAN gateway and comprising a communication interface enabling it to exchange LPWAN frames with said endpoint by means of the first network, wherein the device is connected to each data concentrator by means of a third network and to the server by means of a fourth network, and in that each LPWAN frame exchanged between said endpoint and the server passes through the device, each LPWAN frame exchanged between the device and the server is encapsulated in a second frame in accordance with a frame format that the server would exchange with an LPWAN gateway, and, when an LPWAN frame sent by the endpoint is received directly by a plurality of meters and by a plurality of data concentrators in the second network so that the device receives a plurality of copies of the LPWAN frame, the device is configured to transmit a single copy of the LPWAN frame to the server, said LPWAN frame being associated in the second frame with information representative of one of the meters that directly received the LPWAN frame, chosen by the device in accordance with a predetermined criterion.
A method for exchanging first frames, referred to as LPWAN frames, between an endpoint and a server, said endpoint being configured to exchange LPWAN frames with at least one gateway, referred to as an LPWAN gateway, by means of a first low power long range wireless network, and the server being configured to exchange LPWAN frames with LPWAN gateways, each LPWAN frame exchanged between the endpoint and the server having to pass through at least one meter and a data concentrator connected together by a second powerline communication network and forming a system for the automatic management of readings from a plurality of electricity meters, at least one meter implements an LPWAN gateway and comprises a communication interface enabling it to exchange LPWAN frames with said endpoint by means of the first network the first network, wherein:
