Baseband lan is single channel, supporting a single communication at a time as shown in figure. A baseband bandwidth is equal to the highest frequency of a signal or system, or an upper bound on such frequencies, for example the upper cutoff frequency of a lowpass filter. Broadband lans are extraordinary it is used to support multiple transmission via multiple frequency channels. Whereas baseband uses digital signaling, broadband uses analog signals in the form of optical or electromagnetic waves over multiple transmission frequencies. In the fourier domain, a baseband signal is a signal that occupies the frequency range from 0 hz up to a certain cutoff. It is called the baseband because it occupies the base, or the lowest range of the spectrum. Broadband lan vs baseband lan difference between broadband. A typical wireless base station consists of the baseband processing unit bbu and the rf processing unit remote radio unit rru. It is a lot faster than 3g and 4g internet, and way quicker than the old dialup internet connections.
