I often receive questions from some friends who complain because the connection Internet slow. Though they use 3G and HSDPA connections according to its ads, has the fastest connection. However, when used to automatically download a text file of 200 KB only, why take half an hour more? Can an unknown cause, and then resolved, so the connection can be fast as promised by the service provider?
To be able to find the cause of your Internet connection is sometimes faster and more often slow, you need to know in advance the technology behind the screen.
Internet connection requires three terminals. The first terminal is a device used by the user, namely you. These terminals can be PCs, notebooks, mobile phones and other devices that can be used to open the Internet site. The second terminal connection service providers to the Internet, for example by Speedynya Telkom, Indosat with her Broom, Telkomsel with Flash it, and so on.
third terminal are companies that provide storage services and management of Internet sites. The company was referred to the web-hoster. In some big cities in Indonesia, including Yogyakarta, is there a company of this kind. Often they work with similar companies in other countries that connection and electrical systems are not frequent outages.
Because there are three terminals, the Internet speed is also influenced by the quality of the connection between the terminal one-two-three. If the connection between terminals one and two very fast, but the connection between the terminal two and three were slow, then the result, the connection terminal one to three, to be slow as well.
Connection Type
In addition there are three terminals, there is also a type of connection that connects each terminal. Indeed, for the connection between the terminal two to terminal three, usually a very fast connection. Both the speed of sending data as well as the ability to send data is relatively very large. Therefore, connections are very expensive price. The price of this expensive connection and then sold to its customers, in the capacity of smaller pieces. Well, the connection between customers who use a single terminal and an Internet connection service providers (terminal two) is what you often see his ads.
type of connection there are two major groups. The first group is a group that uses a cable, can be a telephone cable (such as Wasantara and Speedy), cable network (as provided by Jogja Media Net that in Yogya, or also several cable television service providers often unites television services and Internet services), as well as fiber cable optics (such as XL and Indosat). The second group is a wireless service, which currently are offered by various mobile operators and service hotspots in various public places.
cable services, such as those provided by Speedy, distributed through multiple connection points, and each point can be subdivided for multiple users. For example in your area your new home that has a phone line connected to a Speedy, then you can enjoy a self-service. When the promised speed is 384 KB per second, it could be, the speed will not be reduced. However, when all around you there are 7 neighbors who are also connected to Speedy, Telkom can share a single connection point to 8 channels, so that each gets 384 connections divided by 8 to 48 KB per second. With notes, all users together using a computer to open the Internet. When the eight men were not wearing the same time, mean speed remained enjoyed a high, maximum 384 KBPS. It could be argued, his connections ratio is 1: 8, one point is used for 8 users. One advantage of the connection through cable is the number of user should be limited.
wireless services, has characteristics different. Say an operator offers you a fast connection via the GSM network with HSDPA quality, meaning the maximum speed for downloading data is 3.6 MB per second or 3600 KB per second.
That is, if you download an MP3 of the song about 3 MB, it should only need 1 second only. But in reality, why can up to 10 minutes, even 30 minutes? Because at the same time, there are many users who also are using your HSDPA network. How much? No limit! If there are 100 people at the same time also enjoy the Internet with you, then speed becomes 3600 MB divided by 100 people, each will get 36 KB only. Compare this with a wired connection over which only 384 KB per second but only divided by 8 people (ratio 1: 8), the speed is 48 KB per second. Well, so it looks very clear here, HSDPA (3600 KB / sec) is not necessarily superior to a charge equivalent to a 3G connection (384 KB / sec), because the ratio of HSDPA can be 1: 100 or maybe even more.
One example is the connection offered by Smart, which should be reached on the path to 3G CDMA (ie 240 KB / sec), but because it is cheap, so many users, so that when you used to download the file size 200 KB, may take time of 40 minutes, because its speed is only 5 MB per second. That, too, was lucky if I can finish, because it often also can not be completed properly. Choosing
Quick Connection
Now, how do you select the service to a fast Internet connection? Wherever possible choose a number of user should be limited. HSDPA services are currently the most rapid course, because it is not limited to the number of users, so when used to download files, will be very slow. An advertisement in a national newspaper offers an Internet connection 384 MB / sec with a quota (the number of data you download) of 1 GB, taripnya Rp1 million per month? Why so expensive? Yes, because the ratio is 1: 1, that is, the speed is only your own life. To download an MP3 song only takes 10 seconds.
What about the connection without a computer, such as a terminal one, you are using mobile devices. Why do more faster than with the computer? Because when you access through mobile phones, the data is smaller, the images are not loaded, the animation is exceeded, so that was quick.
So you get a fast connection, try to find time when others did not use the Internet. Can be after midnight, may after dawn. But if all people think the same with you, yes it's useless as well. Therefore, we wait hopefully more companies that offer Internet connection services.
