The Router will allow you to network wirelessly better than ever, sharing Internet access, files and fun, easily and securely. How does the Router do all of this? A router is a device that allows access to an Internet connection over a network. When you use the Router, this access can be shared over the four switched ports or via the wireless network. The Wireless-G Broadband Router with SRX200 combines smart antenna technology with standards-based, Wireless-G (802.11g) networking. By overlaying the signals of two Wireless-G compatible radios, the "Multiple In, Multiple Out" (MIMO) technology effectively doubles the data rate. Unlike ordinary wireless networking technologies that are confused by signal reflections, MIMO actually uses these reflections to increase the range and reduce "dead spots" in the wireless coverage area. The robust signal travels farther, maintaining wireless 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 Wireless-G in some situations. The Router avoids interference by dynamically switching to the clearest channel available. Even your standard Wireless-G and -B equipment will work better when communicating with SRXenabled devices. In addition, WPA encryption provides greater security opportunities while the whole network is protected through a Stateful Packet Inspection (SPI) firewall and NAT technology. All of these security features, as well as full configurability, are accessed through the easy-to-use, browser-based utility. But what does all of this mean? Networks are useful tools for sharing computer resources. You can access one printer from different computers and access data located on another computer's hard drive. Networks are even used for playing multiplayer video games. So, networks are not only useful in homes and offices, they can also be fun. PCs on a wired network create a Local Area Network. They are connected with Ethernet cables, which is why the network is called "wired". PCs equipped with wireless cards or adapters can communicate without cumbersome cables. By sharing the same wireless settings, within their transmission radius, they form a wireless network. The Router bridges wireless networks of both 802.11b and 802.11g standards and wired networks, allowing them to communicate with each other. mbps: one million bits per second; a unit of measurement for data transmission browser: an application program that provides a way to look at and interact with all the information on the World Wide Web. lan (Local Area Network): The computers and networking products that make up the network in your home or office 802.11b: an IEEE wireless networking standard that specifies a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz. 802.11g: an IEEE wireless networking standard that specifies a maximum data transfer rate of 54Mbps, an operating frequency of 2.4GHz, and backward compatibility with 802.11b devices.
