This Gateway will provide your computers with a high-speed Internet connection as well as resources, including files and printers. How does the Gateway do all of this? By connecting the Internet, as well as your computers and peripherals, to the Gateway, then the Gateway can direct and control communications for your network. Plus, since the Gateway is wireless, Internet access can be shared over the wireless broadcast as well as the wired network. 802.11b: an IEEE wireless networking standard that specifies a maximum data transfer rate of The Wireless-G ADSL Gateway with SRX200 combines smart antenna technology with standards-based, 11Mbps and an operating frequency of 2.4GHz. Wireless-G (802.11g) networking. By overlaying the signals of two Wireless-G compatible radios, the “Multiple In, 802.11g: an IEEE wireless networking standard Multiple Out” (MIMO) technology effectively doubles the data rate. Unlike ordinary wireless networking that specifies a maximum data transfer rate of technologies that are confused by signal reflections, MIMO actually uses these reflections to increase the range 54Mbps, an operating frequency of 2.4GHz, and and reduce “dead spots” in the wireless coverage area. The robust signal travels farther, maintaining wireless backward compatibility with 802.11b devices. connections up to two times farther than standard Wireless-G. And the farther away you are, the more advantage you get—the higher data rate and reflection-friendly technology can yield up to six times more throughput than wpa (wi-fi protected access): a wireless security Wireless-G in some situations.
