With the rise of the Internet of Things (IoT), the number and sophistication of IoT applications have been increasing rapidly. This has created a growing demand for reliable and efficient power solutions. This paper explores the application scenarios and future trends of Power over Ethernet (PoE) technology in the IoT ecosystem.
**I. Introduction**
The Internet of Things integrates sensors into real-world objects such as power grids, railways, bridges, tunnels, highways, buildings, water supply systems, dams, oil and gas pipelines, and household appliances. These devices are connected via the internet to run specific programs, enabling remote control or direct communication between objects. Through IoT, a central computer can manage and control machines, equipment, and personnel, while also allowing remote control of home devices and vehicles. Additionally, IoT is used for location tracking and theft prevention. In many of these applications, traditional power supply methods are not always feasible, which is where PoE comes into play.
PoE is a technology that delivers both power and data through a single twisted-pair Ethernet cable. It allows devices like VoIP phones, wireless access points, network cameras, hubs, smart terminals, modern office equipment, and computers to be powered without the need for additional electrical outlets. This eliminates the cost and time associated with installing separate power lines, reducing the overall system cost.
As Ethernet becomes more widespread, RJ-45 network sockets are commonly found worldwide, making PoE-compatible devices widely applicable. PoE does not require changes to the existing Ethernet infrastructure, which makes it cost-effective and easy to implement. The “Yulipu†intelligent power supply system effectively addresses the power challenges faced by networked devices, playing a crucial role in the future development of the IoT.
**II. Main Applications of PoE in the Internet of Things**
As technology and applications evolve, the concept of the Internet of Things continues to expand. It represents an extension of communication networks and the internet, using sensing technologies and smart devices to perceive the physical world. Through network transmission, interconnection, computing, processing, and knowledge mining, IoT enables seamless interaction between people and objects, and among objects themselves. This leads to real-time control, precise management, and informed decision-making in the physical world.
In this context, the “Yulipu†system provides key applications of PoE technology in the IoT:
1. **Application of PoE in Wireless Access Points (APs)**
Wireless networks have become essential in various environments, including offices, warehouses, campuses, shopping malls, airports, hotels, hospitals, bars, and cafes. Deploying wireless APs efficiently is critical for providing continuous internet access. However, traditional setups often require separate power sources and complex wiring. The Yulipu power supply switch enables centralized power delivery through Ethernet cables, eliminating the need for local power sources and simplifying AP management. This ensures uninterrupted operation even during power outages.
2. **Application of PoE in Remote Monitoring**
Video surveillance has seen rapid growth, with applications expanding across industries such as finance, government, transportation, and residential areas. However, installing network cameras often faces challenges due to limited power availability. PoE solves this issue by delivering power through the same Ethernet cable used for data transmission. Cameras can be placed in optimal locations without worrying about power supply, ensuring comprehensive coverage and effective security monitoring.
3. **Application of PoE in Smart Terminals**
Smart terminals, such as industrial sensors and actuators, benefit greatly from PoE technology. By using Ethernet cables for power, the need for separate power lines is eliminated, reducing installation costs and improving reliability. Standards like IEEE 802.3af and 802.3at have further advanced PoE, making it a practical solution for powering IP phones, security systems, and wireless routers. The Yulipu system now offers industrial Ethernet products that provide stable power to IoT devices, enhancing their performance and efficiency.
Overall, PoE technology is becoming an essential component of the IoT landscape, offering a reliable, cost-effective, and scalable solution for powering smart devices. As the IoT continues to grow, the role of PoE will only become more significant.
