IoT NETWORK ARCHITECTURE AND WAVELENGTH DIVISION IoT GATEWAY DEVICE THEREOF

Abstract

An IoT network architecture and wavelength division IoT gateway device is provided in the invention includes an optical de-multiplexer and an optical multiplexer that use wavelengths for multiplexing,such that information from different sources can be transmitted on the same optical fiber at different wavelengths in an optical network, thereby greatly improving bandwidth benefits of network information transmission and communication capacity of the gateway device so as to fulfill increasing local communication service requirements and further enhance IoT applications.

Description

technical field [0001] The present invention relates to the field of communication facilities, in particular to an IoT network architecture and a wavelength division IoT gateway. Background technique [0002] The global technological trend is advancing with 5G technology, and the future will be the era of 5G and the Internet of Everything. At present, global telecom operators have actively upgraded 4G (LTE) technology and expanded the application scale of the Internet of Things (ie, Internet of Things; referred to as IoT), including infrastructure, supply chain logistics, asset management and even environmental monitoring. [0003] For now, mobile phones are widely used and 4G services are very mature and diversified. For example, people can use their mobile phones to check the arrival time of buses at nearby bus stops, or check whether the registration of a hospital or clinic is about to arrive...etc. It is very convenient . In response to the advent of 5G technology and ...

AI Technical Summary

Problems solved by technology

In response to the advent of 5G technology and the popularization of networking technology application scenarios, the application of the Internet of Things has the opportunity to be widely used. Therefore, the deployment of IoT networks is very important, and the deployment of IoT networks usually requires gateways as different levels of networks ( Such as the common access point of local area network (LAN) and wide area network (WAN)), however, IoT network deployment is often limited by the communication capacity of the gateway that transmits data

[0004] If the communication capacity of the gateway is insufficient, it will not be able to meet the increasing demand for communication services in the region, and the most effective way to solve this problem is to widely install gateways

However, with the rapid development of urban construction, the urban public land available for telecom operators to set up gateways is decreasing, which brings great difficulties to the location selection of gateways
