How does a Ultra PoE switch differ from a standard PoE switch?
Feb 14, 2022
A Ultra PoE switch and a standard PoE switch both serve the primary function of delivering power and data through Ethernet cables to connected network devices, but they have distinct differences in power output capabilities, range, and application. Here’s a detailed look at how these two types of switches differ:
1. Power Output Capability
Standard PoE Switch:
--- A standard PoE switch adheres to conventional PoE standards, such as IEEE 802.3af (PoE), which delivers up to 15.4 watts per port, IEEE 802.3at (PoE+) at 30 watts per port, and IEEE 802.3bt (PoE++) with power output options up to 60 watts (Type 3) or 100 watts (Type 4) per port.
--- These switches can adequately power devices like basic IP cameras, VoIP phones, and standard wireless access points.
Ultra PoE Switch:
--- A Ultra PoE switch is designed to provide higher power output than standard PoE limits. It can exceed the power specifications set by PoE, PoE+, or even PoE++ standards. The “Ultra” function involves specialized internal power circuitry that can increase the wattage output to support high-power devices.
--- This enhanced power output is essential for devices with higher energy requirements, such as outdoor PTZ (pan-tilt-zoom) cameras with heaters, large LED displays, and industrial wireless access points.
2. Range and Distance Capability
Standard PoE Switch:
--- Typically supports power and data transmission up to 100 meters (328 feet) over Cat5e or better Ethernet cables. This distance is sufficient for most office or home network setups where devices are relatively close to the switch.
--- Beyond this 100-meter limit, the signal strength and power output weaken, necessitating extenders or additional switches for greater distances.
Ultra PoE Switch:
--- Often features the capability to extend the power and data transmission range beyond the standard 100 meters, sometimes up to 200-250 meters or more without additional equipment. This extended reach is beneficial in installations where networked devices are located farther from the main switch, such as in outdoor, industrial, or campus environments.
3. Application and Use Cases
Standard PoE Switch:
--- Ideal for common office, home, and light commercial applications where power requirements are modest. Examples include powering basic IP cameras, VoIP telephones, and standard access points that fit within the typical power budget of PoE standards.
--- Best suited for installations where devices are within 100 meters of the switch.
Ultra PoE Switch:
--- Designed for specialized environments requiring higher power and/or greater range. It is commonly used for:
--- High-powered outdoor surveillance cameras with features like infrared sensors and motorized zoom.
--- Industrial-grade access points that require higher wattage to operate efficiently.
--- Digital signage or displays that need more power than a standard PoE switch can supply.
--- Remote installations, such as perimeter security systems, where power outlets may not be accessible.
4. Port Priority and Power Management
Standard PoE Switch:
--- Typically includes basic power management capabilities, such as port prioritization to allocate power if the total power budget is exceeded. However, it adheres to the limits of the built-in power supply and PoE standards.
--- Some managed standard PoE switches allow limited configuration of power distribution among ports.
Ultra PoE Switch:
--- Often equipped with advanced power management features to effectively manage higher wattage outputs and ensure the stable distribution of power across all ports. This includes enhanced port prioritization to allocate power efficiently based on device needs.
--- These switches may support dynamic power Ultraing, meaning they can adjust the power levels supplied to individual ports based on real-time demands.
5. Cost and Complexity
Standard PoE Switch:
--- More cost-effective and simpler to install and manage. They are widely used in typical network settings where power and data requirements are moderate.
--- Easier for non-technical users to set up and use without specialized knowledge.
Ultra PoE Switch:
--- Generally more expensive due to the enhanced power capabilities and additional features for power Ultraing and extended range.
--- Installation and management might require more knowledge or experience, particularly for more complex, large-scale deployments.

Conclusion
A Ultra PoE switch is a specialized networking tool for applications where high-power delivery and long-distance connectivity are essential. In contrast, a standard PoE switch is suitable for typical environments where moderate power and standard distance are sufficient. Choosing between the two depends on the power demands of your devices, the installation location, and budget considerations.
