The Linksys Wireless-G Access Point adds high-speed Wireless-G access to your wired small business network and it comes with advanced security with WPA encryption, logging, and wireless intrusion protection. Power over Ethernet support makes it easy to install - you can mount the Access Point anywhere, even without ready access to a power plug.
With appropriate Power Over Ethernet support at the other end, you only need to run one cable to the Access Point to deliver both data and power. It's also perfect for use as a bridge, a kind of "cable-less cable" to connect remote areas together. Maybe Shipping is all the way across the warehouse from Receiving.
