The benefits of this enabling technology are not limited to Wi-Fi, however. Many applications that deploy equipment with low power requirements in areas which are not already wired for power will benefit from reduced cabling costs. A single standard Ethernet cable will now be able to provide both power and communication services to IP phones, IP cameras, security badge readers, and many other devices.
A key element in the migration to IP-based communication is the consideration of the network itself. The convergence of voice into a data network has also a created a convergence of power and data in the form of Power-over-Ethernet. The significance of PoE is just beginning to take root in office telephony solutions where traditional phones can be migrated to VoIP capable handsets and powered and networked using PoE capable Ethernet switches.
