An installation requires setting up several wireless access points where electrical outlets are not readily available. Which technology would be MOST suitable for providing the necessary power along with network connectivity to these devices?
Setting up an Uninterruptible Power Supply (UPS) at each location
Using PoE injectors in combination with Ethernet cables
Laying additional standard Ethernet cables alongside power cables
Connecting devices through powerline networking adapters
Power over Ethernet (PoE) is the best option for providing power along with data connectivity to devices through the network cabling. This eliminates the need for multiple cables or power outlets at the device location. PoE Injectors specifically inject power into the Ethernet cable that can be used by devices that are PoE capable. Powerline adapters use existing electrical wiring to send data, which wouldn't be suitable if outlets are not available. An Uninterruptible Power Supply (UPS) provides backup power and is not designed to transmit data. Standard Ethernet cables can't supply power without PoE technology.
