All possible Wired communication protocols that also transmit power supply in IoT [closed]

Question

I am on the lookout for Wired networks deployed in Industrial and other IoT applicable sectors which use cables to transfer Power + Data.

I am aware of:

1. Power over Ethernet (PoE) IEEE standard which sends information and power (48V) over the same CAT5/CAT5e cables so end nodes do not require separate power source.

However I only see this standard for practical applications and widely used throughout many sectors. I am curious which other standards are there juxaposing with PoE or competing with it?

Since CAN is widely used in industries, is there something like Power over CAN ?

Answer 1

As you know PoE is used in practical devices such as:

• IP cameras
• VoIP Phones
• Wireless Access points
• etc.

but I'm assuming what you want to know is other standards similar to PoE for passing data and power.

In that case you should take a look at KNX standard, there is wide list of devices using this standard and commonly used for Smart Homes and IoT purposes.

As stated in the KNX Wikipedia article:

The KNX standard has been built on the OSI-based EIB communication stack extended with the physical layers, configuration modes and application experience of BatiBUS and EHS.

KNX installations can use several physical communication media:

• Twisted pair wiring (inherited from the BatiBUS and EIB Instabus standards)
• Power-line networking (inherited from EIB and EHS - similar to that used by X10) Radio (KNX-RF) based on Z-Wave protocols
• Infrared
• Ethernet (also referred to as EIBnet/IP or KNXnet/IP)

KNX is not based on a specific hardware platform and a network can be controlled by anything from an 8-bit microcontroller to a PC, according to the demands of a particular building. The most common form of installation is over twisted pair medium.
