How Does Broadband Work

Broadband is a communication channel that supports a broader range of frequency compared to the ones used by regular phone lines (baseband). Phone lines are usually used for internet connection, which can only send a maximum capacity of 56kbps of data when coupled with a modem. This makes broadband connection faster and more popular choice for consumers. It is available via ADSL phone lines, wireless fidelity, cable TV, or via satellite.

How does broadband work? Broadband is faster than baseband links because broadband connections is capable of carrying multiple signals. To put it simply, one can think of baseband lines as one channel while broadband lines as multiple channels.

Data from a computer source can therefore be divided and sent simultaneously to its destination using many paths at the same time instead of only having one path to go through. That way, internet connection is quicker and more efficient. One such great analogy to this is the number of lanes a road has. To compare, there would be less road traffic if there are more lanes where vehicles can pass at the same time than just one lane where all the said vehicles pass through one at a time.

But that’s not all. Another thing that makes broadband a fast connection is due to its frequency range. A larger frequency range only means that more data can be placed in a particular channel in contrast to using baseband lines. Going back to the road lane analogy, this means that on one lane there can be more vehicles that can fit at the same time and, which, of course, result to lesser traffic and speedier internet connection.
