Broadband LAN vs Baseband LAN

This page Broadband LAN vs Baseband LAN describes difference between Broadband LAN and Baseband LAN.

In Baseband LAN, digital data is transmitted directly over the medium. No modulation is applied to the data.

Baseband LAN systems are very simple but only one signal is transmitted at one time. Also distance is limited due to attenuation and distortion of the baseband information. Distance covered by this type of LAN is usually about 1 mi with twisted pair and 5 mi with coaxial cable.

In Broadband LAN,digital data signals are translated into higher frequency band before being transmitted over the medium. Here modulation technique is applied to baseband data.

FDM (Frequency Division Multiplexing) is employed to multiplex multiple channels for the binary data signals in broadband LAN systems. Broadband systems use coaxial cables due to larger bandwidth of about 300-450 MHz. Also broadband LAN covers about 10 mi distance. This type of systems are complex and expensive and requires modem at various distance depending upon the need/application.
