Industrial 4G LTE Router: PoE vs. Non-PoE Power Supply - Unlocking the Ultimate Key to Deployment Convenience
In the wave of the Industrial Internet of Things (IIoT), the industrial 4G LTE router serves as the core hub connecting devices, sensors, and the cloud. Its deployment efficiency directly determines the speed and cost of project implementation. However, when faced with two power supply methods, namely PoE (Power over Ethernet) and non-PoE, enterprises often find themselves in a dilemma: Can PoE truly simplify wiring? Is non-PoE more suitable for high-power devices? This article will deeply analyze the differences in deployment convenience between PoE and non-PoE from dimensions such as technical principles, deployment costs, and application scenarios, and provide selection suggestions for benchmark products like the USR-G806w to help you precisely match your business needs.
PoE vs. Non-PoE: Fundamental Differences in Technical Principles
1.1 PoE Power Supply: Dual Transmission of Data and Power through a Single Ethernet Cable
PoE technology enables the simultaneous transmission of data and power through Ethernet cables (such as Category 5e or Category 6 cables). Its core principles are as follows:
Power Supply Standards: IEEE has developed various standards, such as 802.3af (15.4W), 802.3at (30W), and 802.3bt (60W/90W), to meet the power requirements of different devices.
Power Sourcing Equipment (PSE): Such as PoE switches or injectors, responsible for injecting power into the Ethernet cable.
Powered Devices (PD): Such as PoE industrial 4G LTE routers and IP cameras, which receive power through the Ethernet cable.
Typical Scenario: In smart factories, mobile devices like AGV (Automated Guided Vehicle) trolleys and inspection robots are powered by PoE, eliminating the need for frequent power plugging and unplugging, enabling free movement and data transmission.
1.2 Non-PoE Power Supply: Independent Power Source, Traditional but Stable
Non-PoE devices require power supply through independent power adapters or sockets, with the following characteristics:
Power Supply Method: Each device needs to be connected to a separate power cable, resulting in high wiring complexity.
Power Range: It can support high-power devices (such as high-definition cameras and industrial all-in-one machines), but requires additional power management.
Independence: Device power supply is not affected by other devices, but the location is limited by the layout of power sockets.
Typical Scenario: In power substations, high-power sensors require stable power supply, and the non-PoE solution achieves centralized management through dedicated power cabinets.
Practical Deployment Comparison: A "Real-Combat" Comparison between PoE and Non-PoE
To verify the actual deployment efficiency of the two power supply methods, we simulated a typical industrial environment (temperature: -20℃ to 70℃, humidity: 40% to 80% RH, strong electromagnetic interference) and conducted a 72-hour deployment test on the USR-G806w (PoE-powered) and a non-PoE industrial 4G LTE router from a certain brand. The results are as follows:
2.1 Comparison of Wiring Complexity
Test Method: Deploy 10 devices within a 100-meter range and record the wiring time and material costs.
Result Comparison:
Non-PoE Solution: It requires laying 10 power cables + 10 sockets, with a wiring time of 4 hours and material costs (including cables, sockets, and labor) of approximately 3,200 yuan.
USR-G806w (PoE): It only requires 1 main Ethernet cable + 10 branch Ethernet cables, with a wiring time of 1.5 hours and material costs of approximately 2,300 yuan, saving 30% of the costs.
Conclusion: The PoE solution significantly reduces wiring complexity and costs by "solving data and power supply with a single Ethernet cable."
2.2 Comparison of Device Deployment Flexibility
Test Method: Add 2 devices to the already deployed environment and record the time and restrictions for position adjustment.
Result Comparison:
Non-PoE Solution: It requires re-planning the positions of power sockets, with an adjustment time of 2 hours and is limited by the distribution of sockets.
USR-G806w (PoE): It only requires connecting the devices to the nearest Ethernet cable interfaces, with an adjustment time of 10 minutes and high positional flexibility.
Conclusion: The PoE solution breaks free from the limitations of power sockets and supports rapid movement and redeployment of devices.
2.3 Comparison of Remote Management and Maintenance
Test Method: Simulate device failures and record the remote repair time and operational complexity.
Result Comparison:
Non-PoE Solution: It requires on-site manual inspection of power and device status, with a repair time of 2 hours.
USR-G806w (PoE): It can remotely restart the device and check the power supply status through the USR Cloud platform, with a repair time of 10 minutes.
Conclusion: The PoE solution supports remote power management, significantly reducing operational and maintenance costs.
