Ethernet is a widely used data communications network standard developed by DEC, Intel, and Xerox in 1976. Initially it  used a bus topology and CMSA/CD access method.

LANs (Local Area Networks) are high speed data communications networks spanning a limited geographic area, a few miles at most. LANs allows high speed sharing information and computer resources including mass data storage, backup facilities, software printers and processors. The most widely used LAN (Local Area Network) protocols are Ethernet, Fast Ethernet and Gigabit Ethernet.

The first Ethernet supported data transfer rates of 10 Mbps. A newer version of Ethernet, supports data transfer rates of 100 Mbps, 1000 Mbps, Gigabit Ethernet and (10,000 Mbps) 10 Gigabit Ethernet.

RADCOM has a wide range of products supporting connection to lines at rates of 10,100, 1000 Mbps and anlaysis of protocols at all levels, from the physical level, where collisions, CRC errors etc, are identified to the level of TCP/IP protocols and other protocols running above them.
