The Linksys Wireless-G Router for 3G/UMTS Broadband is really three devices in one box. First, there's the Wireless Access Point, which lets you connect both screaming fast Wireless-G (802.11g at 54Mbps) and Wireless-B (802.11b at 11Mbps) devices to the network. There's also a built-in 4-port full-duplex 10/100 Switch to connect your wired-Ethernet devices together. Connect four PCs directly, or attach more hubs and switches to create as big a network as you need. The Router function ties it all together and lets your whole network share a 3G/UMTS or GPRS Internet connection (requires Vodafone Mobile Connect 3G/UMTS data card, available separately). You can also use a standard Ethernet attached Internet connection, like a cable or DSL modem, if available.Once your computers are connected to the Router and the Internet, they can communicate with each other too, sharing document files, a printer, storage space, and other resources.To protect your data and privacy, the Wireless-G Router for 3G/UMTS Broadband can encode all wireless LAN transmissions with WEP or industrial-strength WPA Personal encryption.
