In today’s era of rapid development of the Internet of Things (IoT) and smart devices, WiFi modules, as core components for device networking, directly affect product performance, cost, power consumption, and development cycles.

In the era of the Internet of Things (IoT), WiFi technology—one of the most mature and widely used wireless local area network (WLAN) technologies—has become the core bridge for IoT devices to access networks.

This paper focuses on the customer-proposed "4G master node + LoRa cascade relay" remote control scheme for transmission line towers. Combining technical documents of products from Chengdu Ebyte Electronic Technology Co., Ltd. (EBYTE), it conducts an in-depth analysis of the scheme's feasibility, technical implementation path, product selection recommendations, and potential advantages and challenges. The conclusion shows that the scheme is technically fully feasible, and Ebyte's existing product line can provide mature hardware support.

In industrial automation, data centers, communication base stations, and other scenarios, stable monitoring and intelligent control of the internal environment of cabinets are critical to ensuring the safe operation of equipment

As smart city construction deepens, reliable, long-distance, and low-cost data collection and monitoring of massive, decentralized, low-power IoT terminals have become critical needs

In the fields of Industrial Internet of Things (IIoT), smart cities, and remote automation, stable and reliable wireless wide-area network (WWAN) connectivity serves as the cornerstone of data transmission and device control.

For the composite requirement of a space-constrained (140×60×20mm) Modbus TCP master gateway for 30+ RTU slaves over 5G Wi-Fi, the E103-W06 + STM32 MCU dual-core architecture is the optimal solution based on Ebyte’s existing product catalog. The E103-W06 excels in wireless connectivity (dual-band, high power, reliability, compact size), while the STM32 provides critical intelligent protocol processing.

In industrial automation, data acquisition, and intelligent control systems, reliable signal conversion between USB interfaces and RS-485 buses serves as a critical bridge connecting modern computers to traditional industrial devices.

Traditional point-to-point or basic transparent transmission modules cannot meet complex network management needs (1-to-many, automatic networking, reliable upgrades). Thus, LoRaWAN Gateway + Node (with network-layer protocol stack) is recommended over basic transparent transmission radios.
