Problems solved by technology
[0004] A problem faced by service operators is that some connected objects may be outside the radio range of the LPWAN communication system
Installing the gateway is very time consuming as the function of this gateway (permanently listening to the medium) requires mains power

Embodiment Construction
[0038] The invention is described in more detail below in the context of a LoRaWAN (registered trademark) network infrastructure, particularly using terminology found in the LoRaWAN (registered trademark) specification. More generally, however, the principles and implementations described below do apply in the context of LPWAN network infrastructure.
[0039] In addition, the present invention is more specifically described below using two reception windows in the Class A transmission mode, as in the LoRaWAN (registered trademark) specification. However, it should be noted that different numbers of receive windows in the type A transmission mode may be used, in particular a single receive window in the type A transmission mode.
[0040] figure 1 A communication system in which the present invention is implemented is schematically shown.
[0041] The communication system comprises a plurality of gateways GW with respective communication links to a server device SERV 130 to wh...

An LPWAN communication system includes a server device (130), at least one gateway (120, 121, 122) and at least one repeater (100). Each gateway communicates with terminals (110, 111, 112, 113) using a type A communication mode, wherein any response for a terminal uses a reception window defined relative to the transmission time of the original message by said terminal. Each repeater (100) is regarded as a terminal by each gateway and communicates with the terminal according to the communication mode of class A', defined as follows: The repeater transmits beacons at regular intervals and only in relation to said beacons Listen to the terminal during the time slot. In this type A' communication mode, the repeater propagates any response to the terminal using at least one other reception window defined relative to the transmission time of the original message by said terminal.
Description
technical field [0001] The present invention relates to a relay mechanism between one or more terminals and one or more gateways in an LPWAN (Low Power Wide Area Network) communication system. Background technique [0002] The Internet of Things is on the rise. The Internet of Things represents the extension of the Internet to things and places in the physical world. Whereas the Internet generally does not extend beyond the electronic world, the Internet of Things represents the exchange of information and data to the Internet from devices present in the real world, such as for example for collecting gas or water usage readings, or in general sensor measurements. The Internet of Things is considered the third generation of the Internet, known as Web 3.0. The Internet of Things has a common character for designating communication objects (called "connected objects") for different purposes, for example in the fields of industry, food, e-health or home automation. The object...
