The Linksys Wireless-N Access Point lets you connect Wireless-N (802.11n), Wireless-G (802.11g) or Wireless-B (802.11b) devices to your wired network so you can add PCs to the network with no cabling hassle. Power over Ethernet (PoE) support makes the Access Point easy to install, you can mount the Access Point anywhere, even without ready access to a power plug. With appropriate PoE support at the other end, you only need to run one cable to the Access Point to deliver both data and power. Of course, you can also use the included AC adapter if your installation point has power available nearby.
