LAN extension is an easy solution to the problems created by the limited range of Ethernet cables. A LAN extension device operates at the physical layer, transparent to higher network-layer protocols. LAN extenders forward all traffic between two LANs.

When the source and the destination of a data transmission are very close to each other, as with components of an integrated circuit, we can achieve very high-speed communication with little or no interference. Unfortunately such an ideal environment for data communications is not always practical. As transmission distance increases, the data-transfer signal becomes increasingly susceptible to interference from noise and distortion.

When a computer must be connected to more than one peripheral device, or to other computers, Ethernet LAN connections are commonly used. Standard Ethernet cabling media, however, have some restrictive distance limitations. Using standard CAT5 cable, the connection between the source and the destination begins to break down at 328 feet. Real-world situations frequently require network connections that exceed this Ethernet distance limitation. For such situations, LAN extension devices can provide a valuable solution.

The particular needs of your network will determine the type of LAN extension equipment you should buy. To learn more about the options available, check out Patton's line of Ethernet LAN extenders.
