Power over Ethernet (PoE) is a revolutionary technology that extends the already ultra-broad functionality of Ethernet by supplying reliable DC power over the same twisted-pair cable that currently carries Ethernet data.

PoE, modeled after the technology used by the telecommunications industry to supply reliable power to telephones, enables lifeline quality power for IP telephones (VoIP) as well as many other low power Ethernet network devices like wireless access points (WAP) and security cameras.

When locating access points, system des ....etc

Power Over Ethernet


PoE
¢ Power over Ethernet is a mechanism for supplying power to network devices over the same cabling used to carry network traffic. PoE allows devices that require power, called Powered Devices (PDs),such as IP telephones, wireless LAN Access Points, and network cameras to receive power in addition to data, over existing infrastructure without needing to upgrade it.
¢ This feature can simplify network installation and maintenance by using the switch as a central power source for other n ....etc

Definition

Power line communications (PLC) or Broadband over Power Lines (BPL) allows transmission of data over power lines.Power line communications uses the RF signal sent over medium and low voltage AC power lines to allow end users to connect to the Internet. The RF signal is modulated with digital information that is converted by an interface in the home or small business into Ethernet compatible data.

To gain a good understanding of how PLC Works an excellent understanding of the Power Grid is required. Unlike telephony and it's ass ....etc

Fast Internet access is growing from a convenience into a necessity in all aspects of our daily lives. Unfortunately, this has been held back by the high expenses of wiring infrastructure essential to deliver such high-speed internet access especially to private homes, small offices and rural areas, where the installation of any kind of new wires tilts the scales of the economic feasibility to a non-profitable state. This problem is known as the ?last mile problem? which has been an active area of research throughout research community.
