Description

Technical Field

[0001] This utility model relates to the field of signal conversion technology, specifically a signal spectrum conversion device. Background Technology

[0002] In the construction of smart cities, LoRa can be used in systems such as smart lighting, smart parking, and environmental monitoring to achieve intelligent management of urban infrastructure. After this data is transmitted to a central node via the LoRa network, it can be converted into WiFi signals for data sharing and remote monitoring within WiFi coverage areas throughout the city.

[0003] In agriculture, LoRa technology can be used for real-time monitoring of parameters such as soil moisture, temperature, and light intensity, contributing to the development of precision agriculture. Data collected by sensors is transmitted to a base station via a LoRa network, which then converts the data into WiFi signals, allowing farmers to monitor their farmland conditions in real time using devices such as mobile phones or computers.

[0004] In smart homes, LoRa technology can be used in scenarios such as smart door locks and smart home devices. For example, smart door locks can send data to the home's WiFi router via a LoRa network, and then upload it to a cloud server to enable remote control and monitoring.

[0005] In these fields, devices that convert LoRa to Wi-Fi signals are concentrated in base stations or central nodes. These conversion devices are fixed and cannot be carried around to the place where data conversion, reception, and transmission are needed. Furthermore, it is inconvenient to convert LoRa wireless signals to Wi-Fi wireless signals. Traditional devices convert wired LoRa signals to Wi-Fi signals.

[0006] Therefore, a signal spectrum conversion device is needed to address this problem. Utility Model Content
