Multi-channel full duplex Internet of Things gateway based on LoRaWAN

Abstract

The invention discloses a multi-channel full duplex Internet of Things gateway based on LoRaWAN, which comprises a main control chip and a power supply and further comprises a network module communicating with a mobile network and an Ethernet, a LoRa module used for processing the sent and received LoRa data, and a duplexer connected with the LoRa module and used for isolating the transmitted andreceived data. According to the scheme, the duplexer is used, so that the gateway is changed into FDD from TDD, meanwhile, the number of downlink channels is increased, the communication capacity of the LoRaWAN gateway is improved, and the equipment operation efficiency, the communication quality and the network capacity are improved. The gateway has the substantial effects that data can be received and sent at the same time, the information capacity is high, the uplink and downlink channel proportion is relatively high, and the gateway has the characteristics of high signal intensity, high communication quality, accurate positioning and high power supply reliability.

Description

technical field [0001] The invention relates to the field of LoRa gateways, in particular to a LoRaWAN-based multi-channel full-duplex Internet of Things gateway. Background technique [0002] LoRaWAN is a widely used wireless connection technology in the wireless Internet of Things industry. Most of the LoRaWAN gateways currently on the market are TDD (time division duplex communication), and most of the receiving and sending channels are 8RX+1TX or 16RX+2TX. Most of the data return methods are Ethernet and 4G. Compared with FDD (Frequency Division Duplex), TDD has many disadvantages, such as unreasonable ratio of uplink and downlink channels, downlink channel congestion seriously affects network capacity, small coverage radius, limited transmission power, and requires more complex network planning and optimization technologies, etc. . [0003] Reference document: The utility model with the publication number CN208424796U discloses a LORA Internet of Things gateway, incl...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problems of low operating efficiency, weak signal strength, unreasonable allocation of hardware resources, and seriously unbalanced ratio of uplink and downlink channels in the existing technology, the present invention provides a multi-channel full-duplex IoT gateway based on LoRaWAN, using The duplexer makes the gateway change from TDD to FDD, increases the number of downlink channels at the same time, provides a high communication capacity of the LoRaWAN gateway, and improves equipment operation efficiency, communication quality and network capacity
