Title:
COMMUNICATION GATEWAY INTENDED TO CONNECT AN LPWAN NETWORK AND A CELLULAR NETWORK
Document Type and Number:
WIPO Patent Application WO/2021/233922
Kind Code:
A1
Abstract:
The invention relates to a communication gateway intended to connect an LPWAN network to a network for access to a cellular or RAN network, the LPWAN network and the RAN network using radio links. Such a gateway typically allows connected objects and servers on the Internet to communicate according to the Internet of Things (IoT) architecture. However, the proximity of the frequency bands used for the two radio links may lead to mutual interference between them, the transmitter of one interfering with the receiver of the other, especially when the gateway is miniature, of the order of magnitude of the connected objects (approximately 10 cm). The present invention proposes a solution for electromagnetically isolating the two RF channels by means of double filtering: by a bandpass filter on the LPWAN RF channel combined with a rejection filter on the cellular RF channel.
