In Telecommunications It Pays to See the Major Picture
We all know that telecommunications is an region that sees just one technology advance right after yet another, in speedy fire succession.
What, at occasions, is not so apparent are the implications of these technological know-how developments, significantly when it will come to telecommunications expenditures.
Just now, there is a virtual revolution having position in telecommunications, all summed up in 1 phrase — convergence. Convergence is a phrase we examine a large amount about, but just what does it mean?
Overview of convergence
In all probability the most effective way of knowledge convergence is to consider an case in point with which we are all acquainted. We have all lived at some time or an additional in residences that count on possibly gasoline or electricity for heating and cooking. We know that you are unable to take a gas oven and plug it into an electrical electric power level and count on it to do the job, and vice versa. Nonetheless, in the environment of telecommunications, thanks to the magic of convergence, you can do the equivalent. If you use your mobile telephone to obtain photographs from the Internet, this is convergence. Applying your landline to make a voice phone get in touch with and download from the Net concurrently is nother illustration of convergence. The record goes on.
Mobile phones and landlines are examples of two various networks, the cell network and the community switched phone network (PSTN).
Then there is โปรเน็ตทรู of network, usually referred to as a information network. This is the kind of network that makes it possible for an organisation to ship data amongst its many branches. Facts can be any kind of digitised materials, these kinds of as the output from a financial accounting process. The PSTN community has been all around for a quite extensive time now and facts networks have also existed in commercial organisations for quite some time. The mobile community is reasonably extra the latest.
Till fairly lately, organisations applied the 3 networks independently of every single other. The see was taken that each individual experienced its have occupation to do. So no just one anxious about the expense of preserving a few unique networks. This was taken as an unavoidable section of business. The end result was that when administrators in organisations preferred to assessment their telecommunications expenses, they tended to concentrate only on get in touch with fees — the fees they experienced to spend carriers to make fastened line and cell calls.
Reviewing simply call fees is continue to a legitimate and required work out but, as a consequence of convergence, there are numerous other factors to look at when examining telecommunications expenditures. Convergence has resulted in possibilities which in flip signifies that decisions have to be manufactured. Likely back to our initial illustration, if you have an oven which can functionality by becoming plugged into possibly your gasoline strains or your electrical circuits, you can now decide on no matter whether you want just gasoline lines or electrical circuits or equally. If equally offer you the identical utility in conditions of finding your oven to do the job, it results in being a make any difference of expense. Why pay back for both fuel traces or electrical circuits if just just one will do the career? And if, say, gas traces are considerably less costly than electrical circuits, why pay out the more for electrical energy?
Relating this again to the three forms of telecommunications networks, we have now achieved the stage wherever each individual of the networks can help other network functions. Some people today go so significantly as to say that, inside of the upcoming 20 decades, the 3 networks as we at this time know them will vanish, to be changed by a solitary network capable of supporting voice, cellular and knowledge telephony.
Whilst we may possibly not rather have reached that phase, we have surely achieved the stage where voice telephony is able of remaining carried on a knowledge network, generally referred to as IP telephony. We can also say that in idea, voice over information networks could supply a potential 90 per cent reduction in phone fees.
The catch is that issues are not really that uncomplicated. Enterprises might have to spend cash on infrastructure and the like to accomplish IP telephony and the problem then will become no matter if this sort of telephony is price-successful. So we arrive appropriate back again to the assessment of costs as a essential determinant in examining the usefulness of know-how advancements in telecommunications.
