摘要： The invention relates to the extension of a Low Power Wide Area Network (LPWAN), especially a Long Range Wide Area Network (LoRaWAN), specification for wireless battery powered systems in a regional, national or even global network to provide a solution, with which LoRaWAN-compatible end devices also benefit from range extension, which is achieved by dividing the gateways into several front-end gateways communicating with each other and with each other via a wireless multi-hop communication network and at least one border gateway.

摘要： The invention relates to a method for communication in a LoRaWAN mesh gateway network, wherein the LoRaWAN mesh gateway network has a plurality of end devices, a plurality of gateways and a network server. Here, one of the gateways performs server functions of the communication method that are intended for the network server (NS) according to the LoRaWAN protocol.
