The global power over ethernet market is experiencing explosive growth as smart buildings, data centers, and IoT-driven infrastructure proliferate worldwide. Valued at USD 1,352.6 million in 2023, the market is projected to grow from USD 1,631.9 million in 2024 to USD 6,901.1 million by 2031, representing a compound annual growth rate (CAGR) of 22.87%, one of the steepest growth curves among networking hardware categories tracked today.
What Power Over Ethernet Enables
Power over ethernet (PoE) technology allows a single ethernet cable to simultaneously carry electrical power and data, eliminating the need for separate power wiring for networked devices. The market encompasses power sourcing equipment (PSE) controllers and ICs, which supply power, and powered device (PD) controllers and ICs, which receive it. Applications span networking infrastructure, security and access control systems, commercial and automotive infotainment, LED lighting and control, and broader smart building technologies, making PoE a foundational enabler of connected environments.
Smart Buildings and Data Center Expansion Drive Growth
The single biggest catalyst behind PoE’s rapid growth is the accelerating adoption of smart building automation combined with the parallel expansion of data centers and network infrastructure. As commercial and residential developments increasingly embed intelligent lighting, security cameras, and access control systems, PoE has emerged as the preferred method for powering and connecting these IoT-driven systems, primarily because it simplifies installation, cuts wiring costs, and improves overall energy efficiency.
At the same time, the buildout of high-speed network infrastructure and cloud computing capacity is generating substantial demand for PoE-enabled networking equipment. As enterprises lean further into cloud services, 5G connectivity, and unified communication systems, PoE provides the seamless power-and-data delivery needed to support a rapidly growing number of interconnected devices. NTT Ltd.’s launch of its Chennai 2 hyperscale data center campus in June 2023, featuring a planned capacity of 34.8 MW across two buildings, illustrates the scale of infrastructure investment fueling this demand.
Heat Dissipation Presents a Technical Hurdle
As PoE standards push toward higher power delivery, the market faces a genuine engineering challenge: managing heat dissipation in high-power applications. While the IEEE 802.3bt standard has extended power delivery to as much as 90W per port, these higher transmission levels generate additional cable heat, which can degrade performance, waste energy, and introduce safety risks in densely packed network installations.
Manufacturers are addressing this by refining cable designs and adopting more sophisticated power management techniques. Higher-category ethernet cables with improved heat dissipation properties are increasingly being deployed to mitigate overheating risks, particularly in installations supporting high-wattage devices such as digital displays and industrial equipment.
High-Power PoE and Smart City Integration
A defining trend reshaping the market is the extension of PoE beyond conventional networking into higher-power applications such as digital displays, industrial automation equipment, and advanced security cameras, made possible by the IEEE 802.3bt standard’s expanded power ceiling. This shift is improving scalability while reducing power infrastructure costs for enterprises adopting the technology at scale.
LED lighting integration represents another major growth avenue. PoE-enabled lighting systems allow centralized control, remote dimming, and automation, features that are reshaping energy management in both commercial spaces and urban environments. The technology is also gaining ground in smart city deployments, supporting intelligent street lighting, traffic monitoring, and surveillance networks. Ikan’s January 2024 launch of its patent-pending LBX8-POE and LBX10-POE lighting products, which operate over a single ethernet cable and eliminate traditional wiring needs, exemplifies how manufacturers are capitalizing on this trend to reduce installation complexity and cost.
Segment-Level Insights
By type, power sourcing equipment controllers and ICs led the market in 2023 with USD 736.1 million in revenue, driven by rising deployment of PoE-enabled infrastructure across enterprise and industrial settings. By application, connectivity held the largest share at 28.47% in 2023, reflecting surging demand for seamless data transmission across smart buildings, data centers, and enterprise networks; this segment is projected to reach USD 1,973.3 million by 2031. By end user, the commercial segment is expected to generate the highest revenue, an estimated USD 2,853.6 million by 2031, propelled by widespread PoE adoption across office spaces, retail environments, and hospitality settings for networking, security, and automation purposes.
Regional Analysis: North America Leads, Asia Pacific Accelerates
North America accounted for the largest regional share in 2023, at 33.75%, equivalent to USD 456.5 million, a position reinforced by the region’s advanced IT infrastructure, widespread smart building adoption, and a mature ecosystem of networking and telecom companies. The United States, in particular, benefits from significant enterprise networking investment, an expanding data center footprint, and the presence of major technology providers including Cisco, Broadcom, and Texas Instruments, all of which continue to drive PoE-related innovation.
Asia Pacific is poised to be the fastest-growing region, with a projected CAGR of 23.87% through 2031 and an estimated market value of USD 1,612.9 million by that year. This growth is fueled by rapid industrialization, urbanization, and the proliferation of smart city initiatives across China, India, Japan, and South Korea. Rising investment in digital infrastructure, coupled with expanding co-working spaces and hybrid work environments, is further accelerating regional PoE adoption. CtrlS’s February 2025 inauguration of its Namma data center park in Chennai, spanning 1 million square feet with a total capacity of 72MW, underscores the scale of infrastructure development supporting this growth.
Regulatory Environment
In the United States, the Federal Communications Commission regulates PoE devices to ensure electromagnetic compatibility and safe operation within networking environments. In Europe, PoE devices fall primarily under the Low Voltage Directive and the Electromagnetic Compatibility Directive, which together address insulation standards, electrical shock prevention, and fire hazard mitigation, ensuring devices operate safely within defined voltage limits.
Competitive Landscape
Companies across the PoE ecosystem are investing heavily in R&D to deliver higher power output, improved energy efficiency, and tighter integration with IoT and smart building platforms. The introduction of advanced PoE controllers and ICs tailored for next-generation networking infrastructure has intensified competitive dynamics industry-wide. Firms are also expanding product portfolios with higher-wattage switches, injectors, and splitters designed to support demanding applications such as security cameras and wireless access points, while integrating intelligent power management features that enable remote monitoring and enhanced network security. Strategic alliances with telecom operators and cloud service providers, alongside expanding distribution networks, remain central to competitive strategy. In February 2024, Edgecore Networks introduced its ECS4650 Layer 3 Ethernet Switch series, including a variant offering up to 90W of PoE to support high-power devices such as wireless access points, VoIP phones, and IoT equipment.
Outlook
With smart infrastructure investment accelerating globally and PoE standards continuing to evolve toward higher power delivery, the power over ethernet market is well positioned for sustained double-digit growth through 2031. Vendors that can effectively address thermal management challenges while expanding into high-power applications stand to capture the largest share of this rapidly scaling opportunity.
