Wondered Just What Is Broadband

We all know the word broadband today as something we use to connect to the internet, but just what is broadband, and what does it mean?

The official explanation is “The term broadband refers to the wide bandwidth characteristics of a transmission medium and its ability to transport multiple signals and traffic types simultaneously. The medium can be coax, optical, twisted pair or wireless. In contrast, baseband describes a communication system in which information is transported across a single channel” Clear?  No, its amazing how a simple explanation can end up confusing everyone.
Put basically a cable which can contain copper or optical (glass filaments) and which can transmit multiple signals along one cable to its destination.
Now we can all get caught up in the discussion on which is the best broadband, but there is no doubt that fibre optics is the fastest way to carry a huge number of signals down its line.  There is simply nothing to slow it down, as the pulses of light hurtle down the glass filaments of this broadband cable.
Compare that to copper wire broadband cable, and you have an element that is susceptible to problems. The problem with ol’copper is that the speeding packets of data cause electrical noise, which creates interference, or cross talk, with the connections of others flowing down the next adjacent cable. This in turn reduces the maximum speed you can push through the ancient copper cables that link our houses to the network.
But the real decider is this fact. A copper wire only holds bandwidth over about two kilometres, wear as Fibre maintains full bandwidth over a distance of 200 kilometres.
So, what does all this boil down to for broadband users? When choosing between fibre and copper wiring, most home and personal users find it difficult to justify the costs associated with fibre optic cable services, which can be a very high price. The exceptions are people who work from home, small business owners, serious gamers, and people who engage in heavy bandwidth applications such as video and music streaming in their jobs.
For business users, the choice is clear for Business Internet Broadband. In today’s online world, businesses simply can’t remain competitive with unreliable, less secure, slower copper cables. Companies and organizations simply must have the dependability and reliability that only fibre can offer.
As fibre cables continue to become more affordable, home and personal users are likely to follow suit. In another decade or two, fibre might well replace slower, less reliable copper cables for Internet service entirely.
The bottom line when selecting between copper and fibre technologies is price. If you can justify the higher cost of fibre cables, it pays off in terms of reliable service, fast speeds, and greater security.
So if you are moving to a new house, or you are considering having broadband into your home, think carefully, as to which of these is best for you, but at a price you can afford.  Fibre is beyond doubt the best medium, but it comes down to cost.  Can you afford Home Internet Broadband every month.
