Challenges for PoE in the New Age

Home / Blog / Challenges for PoE in the New Age

We are going through an era of the digital revolution with advanced digital technologies, cloud-based control systems, remotely operated power transmission methodologies, etc. The Power over Ethernet (PoE) is such an invention to meet power requirements without the installation of an additional electrical cable. By utilizing PoE, one can reduce expenses on additional cabling, observe better space management, and get enhanced efficacy in operations.

What is PoE?

The Power over Ethernet technology explores the electricity carrying capability of network cables in turn precluding the requirement of two different cables, i.e. one for power and the other for data or network.  Using this technology is very much advantageous and cost-effective.

It helps the firms to provide electrical connections to systems and devices, wherein electrical cabling is not available. Simply install a telephone connection and use it as the power source. The Institute of Electrical and Electronics Engineers (IEEE) has identified and formulated the standards to obviate any ambiguities and ensure proper functioning. Cables with certain specifications can carry electricity for a distance up to 100m, in addition to performing the duty of the network carrier.

Benefits of Using PoE

Although PoE puts up certain challenges (which we will discuss in the latter part of this article), it offers significant benefits.

  • Cost-effective – PoE is a cost-effective method for providing power and data. A single cable is used for both power and network, reducing the need to undertake multiple cabling. Therefore, the expenditure for labour, additional cable, and other extra fittings.
  • Optimal Performance – The technically advanced PoE system optimal performance, supporting the functioning of the systems without any lacunae.
  • Scalable Option – Scalability is a necessity in these times. New inventions, the introduction of novel technologies, the updating of software, and the addition of high-performing devices are happening on a daily basis. The PoE technology can adapt to the changes without any exhaustive modifications.

Challenges Encountered by PoE (Power over Ethernet)

Every digital platform and invention undergoes constant changes and technical enhancements to eradicate faults and improve performance. Experts will identify new modifications to eliminate erroneous functionalities and frequent issues. The same is the case with PoE as well. The technology faces a few challenges that could be handled effectively by obtaining dedicated support from the OEM and selecting guaranteed products.

  • Aftereffects of Power Fluctuations – The power fluctuations or constant loss of electric supply can be problematic at times. It may lead to a reboot of the systems and adversely affect the system-based activities. Consequent to errors in the power, the system may appear shut down and stop functioning altogether.
  • Defects in Cabling – Perfect cabling is mandatory for the PoE to perform continuously. The defects in cabling, including short circuit, open cabling, or split pairs can disrupt the functioning.
  • Eliminate Unwanted Power Factors – Filtering out the factors that can hamper the operation of PoE is essential. Induced power problems from attached devices can falter the system. Or any external impulse such as a thunderstorm can overload the servers and can result in cascading effect/ complete failure.
  • Improper Installation and Non-compliance of Laid Down Standards – Some manufacturers may consider following the standards derived by them. They may not consider the standard formulated by IEEE. It may turn problematic for your network/ power systems. Moreover, improper configuration/ installation and unproven system spec can affect the functioning.
  • Size of the Network/ System – PoE has to be designed and finalized depending on the size of the network or system. A generic PoE may not work in every network, irrespective of size. In case, one is seeking the technology for a wider network, it must be conveyed to the manufacturer. The competent agency will develop the system and associated equipment accordingly. Necessary augmentation would be required for maintaining the speed of data also.
  • Overheating Issues – The power requirements have increased largely over a period. It has become more than double, from the maximum limit of 30W earlier. Consequently, four pairs of cables have to be used in place of two, causing overheating of the cables.  This will adversely affect performance, besides being a safety hazard.  However, this problem could be resolved by observing the following measures.


  1.  Using a cable with a low gauge
  2. By using reliable and higher category cables
  3. By properly planning the cable management
  4. Using cables with metal sheathing
  5. Installing metallic connectors instead of plastic

How to Ensure Better Functioning of PoE?

Reputed firms offering PoE will provide you with a comprehensive solution for the challenges. They will have laid down, foolproof, procedures to ensure the ideal functioning of the system. The methodologies invented after in-depth research and development would help to eliminate faults.
