baseband LAN

The baseband network is the dominant network type for local networks. In this technology, the data is placed directly, i.e. unmodulated, on the transmission medium and transmitted.

In order for baseband networks to transmit data at high and highest data rates, the transmission media must be extremely broadband. Since the enormously high data rates could not be realized with the bandwidths made available by baseband technology, the data signals are encoded using a wide variety of coding methods. Only in this way can data rates of 1 Gbit/s and higher be achieved.

All known local networks such as Ethernet, Token Ring, Fibre Channel or FDDI are based on baseband technology. Transmission speeds range from 1 Mbit/s in the 1980s to 10 Mbit/s and 100 Mbit/s in the 1990s to 1 Gbit/s and 10 Gbit/s after 2000. Baseband networks are structured in bus, ring and star topologies and can use a wide variety of access methods.
