The Gateway?? Wireless-G PC Card is 54Mbps wireless networking standard that's almost five times faster than the widely deployed Wireless-B products found in homes, businesses, and public wireless hotspots around the country. While Gateway's Wireless-G products are optimized for working within a fully integrated Gateway network, they have been designed to be compatible within any established Wireless-G network. Gateway Wireless-G devices are also backwards compatible with existing 11Mbps Wireless-B equipment. This will give you instant network access through your notebook with a simple plug-and-play device - whether it's Wireless-B or Wireless-G! This lets you be productive and in touch by checking your email, surfing the Internet, sharing printers, network storage - from wherever your network extends.
