Wireless Hacks: Send Power Over Your Ethernet
Overview A number of access point manufacturers (Proxim, Symbol, and D-Link, to name just three) are now offering Power over Ethernet (PoE) add-ons for their access points. PoE modules insert DC voltage into a standard Ethernet cable. The idea is to supply the AP's power and UTP Ethernet connectivity requirements via a single Ethernet cable. This works great in areas where one might not have power easily accessible, such as a roof. This also allows one to more easily place the AP closer to the antenna, thus reducing signal loss over antenna cabling. Ethernet signal travels well over CAT5 cable; a 2.4 GHz signal doesn't do as well over antenna cabling. Also, Ethernet cabling is much cheaper than antenna cable such as LMR400.
