The Wireless Point-to-Point Ethernet Extender Kit gives you a quick way to extend an Ethernet link between buildings. Because it's wireless, you avoid the hassle and expense of laying cable.You get a 40-Mbps wireless link up to 3 miles away - and that's enough bandwidth to support several workstations - with lower speeds at longer distances of up to about 6 miles (9.6 km).The kit comes with two wireless extender units synchronized to work together. Mount each on a building within line of sight of each other. The extenders are waterproof, weatherproof, and compact - about the size of a bottle of water. They blend unobtrusively into building architecture without large, unsightly antennas.What's more, the kit's extender units don't require a nearby power outlet because they receive their power through the Ethernet cable via a 12-VDC power injector included with each extender unit.The extender units also offer easy setup. An LED indicator shows when the extenders are properly aligned and receiving a strong signal.Use the Wireless Point-to-Point Ethernet Extender Kit in any number of wireless extension applications, including last-mile access for broadband networks. Quickly and economically extend your network's reach to areas such as guard stations or utility buildings, or any site where it's not cost effective to run cable for just one or two workstations.And, for data security, the extender kit uses 64-/128-152-bit WEP encryption, WPA/WPA2 and pre-shared key WPA-PSK/WPA2-PSK protocols, as well as IEEE standard 802.1X authentication.
