Power over Ethernet (PoE) technology sends electrical power and data to connected devices over the same eight-wire Ethernet cable that connects to the network. This technology enables organizations to deploy devices, such as wireless access points, IP cameras, and access control readers, in areas where power is unavailable.
The Institute of Electrical and Electronics Engineers (IEEE) maintains standards for PoE technology to ensure interoperability among PoE-enabled devices. The 2003 IEEE 802.3af standard set a maximum power flow of 15 watts for a Category 5 (Cat 5) Ethernet cable. In 2009, IEEE issued its 802.3at standard, which increased this limit to 30 watts over a Cat 5 cable.
In 2018, the IEEE issued its 802.3bt standard, expanding the use of PoE in office buildings. The IEEE 802.3bt standard supports two device types. Type 3 devices are rated for 60 watts of power, while Type 4 devices have a maximum of 100 watts. These high-power (Hi-PoE) standards mean the technology can support energy-intensive devices such as digital displays, kiosks, and thin clients.
PoE-Enabled Thin Clients
Thin clients handle user interface tasks, such as displaying graphics and receiving input, while leaving heavy processing tasks to the servers. This configuration makes for easier management, reduced energy consumption, and lower hardware costs. Laptops can replace desktops for greater mobility.
Conference rooms no longer require power strips to support dozens of powered devices. Instead, a single Ethernet connection can provide both power and data. Leveraging PoE in the workplace eliminates inefficient mazes of power cables. With an uninterruptible power supply (UPS), work can continue even during power failures. Thin clients are just one example of how Hi-PoE technology is changing the modern workplace.
Government Incentives
More countries are looking at ways to reduce energy consumption. In the United States,the Inflation Reduction Act of 2022 is expected to create a surge of investment in smart building technology to increase the efficiency of our resource use. According to the U.S. Department of Energy, buildings account for about 37% of the country’s energy consumption.
A recent StateTech article reported that PoE technology “simplifies and streamlines the deployment of smart building devices by delivering power and data over a single Ethernet cable.” PoE lowers installation costs because a licensed electrician is not required to install network cables. Other benefits include:
- PoE technology uses DC voltage, which is far less dangerous than the 110 or 220 volts of AC power used in traditional building electrical wiring in buildings
- Managed PoE switches control the amount of power sent to connected devices, allowing for better network power management.
- Without the limitations of needing an electrical outlet, PoE equipment gives organizations more flexibility in how and where they place their devices.
Because PoE supports nationwide sustainability efforts, government incentives are available to make implementing this technology even more lucrative.
Smart Buildings
PoE technology is changing how experts approach smart building design. Although originally intended for use with voice-over IP (VoIP) phones and security cameras, today’s PoE solutions can be used for asset tracking, occupancy sensors, and human-based lighting. Many LED lighting products are part of an open platform, allowing for data sharing and centralized control.
With an open PoE platform, systems can connect using the same protocols, allowing interoperability among building management applications. The increased versatility of PoE technology and its application partners expands integration options for PoE-driven buildings and adds to the list of potential benefits. For example, PoE technology can lower costs, improve energy efficiency, and provide a more productive work environment.
Consolidation
PoE consolidates a network’s infrastructure by reducing the reliance on dedicated power sources for PoE-enabled devices. Troubleshooting is made easier by PoE switches that provide instant alerts, monitor performance, and regulate power. Integrating PoE technology into a network can save time, materials, and labor. Incorporating an open PoE platform facilitates data sharing between applications for more cost-effective building management. Strategic placement of PoE switches can maximize coverage. Less equipment means less maintenance, which frees up resources for more critical tasks.
Efficiency
Environmentally conscious business practices are the cornerstone of sustainability. PoE minimizes energy loss through centralized power distribution. Intelligent PoE-enabled switches allow administrators to schedule operations to reduce power when not in use.
For example, NetApp used PoE technology to create a sustainable and energy-efficient office space at Wichita State University’s Innovation Campus. When Waldinger Corporationneeded to replace lighting that was expensive to operate and difficult to maintain, they adapted by adding PoE-based lighting to its network. These success stories demonstrate the practical benefits of PoE technology in real-world business settings.
Productivity
The work environment influences employee performance, job satisfaction, and productivity. Employees perform at their best in a well-designed workplace.
To that end, PoE technology allows businesses to automate control of the physical workplace. Heating and cooling sensors can identify temperature changes and automatically adjust for a crowded conference room or a single-person office. Occupancy sensors can detect empty spaces and turn off lights automatically.
A connected workplace becomes a smart workspace when technology monitors and controls the physical environment for maximum productivity. Consolidating data and centralizing control not only saves money and mitigates environmental impact but also improves the health and well-being of employees.
Investing in PoE in the Workplace
Work is no longer confined to the cubicle. Modern work happens in shared spaces and with collaborative tools. Investing in PoE technology ensures that, however the workplace landscape evolves, organizations can provide an energy-efficient environment that encourages employee productivity.
Whether deploying thin clients or video-conferencing displays, PoE solutions deliver user-friendly alternatives for improved performance. PoE can integrate with application partners to deliver data from the edge for energy-efficient operations. With self-correcting capabilities, PoE switches can optimize resources, leading to significant cost savings and a strong return on investment (ROI).
