Local-area networks (LANs) send and receive data at rates much faster than can be transmitted over a telephone line; but the distances are limited, often to a few hundred feet maximum without using costly, long-range technologies, such as Long Reach Ethernet (LRE) or wave-division multiplexing (WDM). Because of distance limitations, LANs are found in small areas such ...
