This kit includes a pair of auto-rate Ethernet extenders, using a standard 2-wire connection, which simplifies your life and provides a cost-effective network extension by enabling you to make the most of your pre-existing twisted-pair infrastructure.You''ll be able to connect remote LANs across distances and at speeds previously unheard of. An auto-rate feature ensures that you achieve the highest possible speed on each connection.It''s easy to use, too. Plug-and-play means that you''ll be up and running in seconds, and the built-in MDI-X works with either straight-through or crossover cables.The pair auto senses the data rate up to 11.4 Mbps at a distance of 4750 feet (1450 m) to provide reliable broadband connectivity with full-duplex symmetric rates, with lower speeds at longer distances of up to about 5.2 miles (8.4 km).
