This kit includes a pair of auto-rate Ethernet extenders, using a standard 2-wire connection, which simplifies your life and provides 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 autosenses the data rate up to 22.8 Mbps at a distance of 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.
