What Devices Use 90W PoE?
Power over Ethernet (PoE) technology has been a game-changer in simplifying network infrastructure by providing both data and power over a single Ethernet cable. Over the years, the power capacities of PoE have evolved, and with the introduction of PoE++ (IEEE 802.3bt) standards, higher wattages like 90W PoE have expanded the scope of devices that can be powered through Ethernet cables. But which devices require 90W PoE, and why is this higher power standard necessary?
Understanding 90W PoE
PoE works by transmitting electrical power alongside data over Ethernet cables, reducing the need for additional power lines or outlets. While standard PoE delivers up to 15.4 watts and PoE+ can provide up to 25.5 watts, the PoE++ standard, which includes the 90W PoE variation, delivers much more power—up to 90 watts per port. This increase enables devices that need higher power requirements to operate effectively without the need for separate power sources.
Devices That Utilize 90W PoE
The need for higher-power PoE solutions, like those offered by a 90W PoE switch, is driven by the growing power demands of advanced devices in modern networks. Some common devices that benefit from 90W PoE include:
1. High-Power IP Cameras
Modern security systems often require high-resolution cameras, including 4K and PTZ (Pan-Tilt-Zoom) models, that can consume significant power for both imaging and movement features. These cameras may require additional power to support integrated heaters for outdoor use, built-in microphones, or advanced analytics capabilities. Using a PoE++ switch to deliver 90W PoE allows these cameras to operate without needing an additional power adapter, streamlining the installation process.
2. Wireless Access Points (WAPs)
Wi-Fi access points used in large-scale environments, such as airports, shopping malls, and industrial complexes, often require significant power to handle high traffic loads and provide stable, high-speed internet connections. Advanced access points supporting Wi-Fi 6 (802.11ax) or multiple antennas for broad coverage require more than the standard PoE can provide. A 90W PoE switch delivers the necessary power to these devices, ensuring optimal wireless performance across a network.
3. Digital Signage Displays
Digital signage, widely used in public spaces like retail stores, transportation hubs, and entertainment venues, demands significant power for both the screen display and additional functions such as interactive touch screens or integrated speakers. A 90W PoE setup allows these large displays to receive both power and data over a single Ethernet cable, reducing the clutter of multiple cables and simplifying installation in hard-to-reach areas.
4. VoIP Phones with Video Features
While standard VoIP phones are typically powered by lower wattage PoE standards, modern VoIP phones with video conferencing features, large touch screens, or advanced audio capabilities may require more power. 90W PoE ensures these devices are powered effectively without the need for an additional power supply, which is particularly useful in environments with multiple devices spread across a wide area.
5. PTZ and Thermal Cameras
PTZ (Pan-Tilt-Zoom) cameras, which are often used in security and surveillance applications, require significant power to operate their motors and zoom functions. Thermal cameras, which are used in industrial or surveillance settings, also need more power for their imaging and processing capabilities. Both types of cameras are perfect candidates for a PoE++ switch delivering 90W PoE, as it allows for reliable, continuous operation without the complexity of separate power cables.
The Role of Industrial PoE Switches
To power these advanced devices, a 90W PoE switch is required, and when used in industrial environments, an industrial PoE switch becomes an even more critical component. These switches are built to withstand harsh conditions, such as high temperatures, vibration, and moisture, which are common in manufacturing plants, warehouses, and outdoor settings. Industrial PoE switches ensure that high-power devices like cameras, access points, and signage displays stay powered and operational in rugged environments, all while maintaining the benefits of PoE technology—simplified infrastructure and centralized power management.
The growing range of devices requiring higher power standards makes it increasingly important for businesses to adopt PoE++ solutions. With a 90W PoE switch, devices that once required separate power supplies can now be powered over Ethernet, reducing installation time and complexity while ensuring reliability and performance across the network. Whether in a commercial, industrial, or retail setting, the ability to power a variety of devices with a single cable solution is transforming the way modern networks are built.
