Wireless-G is the 54Mbps wireless networking standard that's almost five times faster than Wireless-B (802.11b) products - but since they share the same 2.4GHz radio band, Wireless-G devices can also work with existing 11Mbps Wireless-B equipment. The Linksys Wireless-G Access Point lets you connect Wireless-G or Wireless-B devices to the network. Since both standards are built in, you can protect your investment in existing 802.11b infrastructure, and migrate your network clients to the new screaming fast Wireless-G standard as your needs grow. To protect your data and privacy, the Wireless-G Access Point can encrypt all wireless transmissions. The MAC Address filter lets you decide exactly who has access to your wireless network.
