ADSL modem is a computer network device which stands for Assymmetric Digital Subscriber Line which has the function of channeling communication via data. This data will be sent quickly via asymmetric copper cables or telephone cables. This asymmetry means that the data sent has applied a different speed from one side to the other.

This modem is also defined as a tool that can make a computer connection via the internet. Through this modem technology, the data transferred can reach 1.5 mbps to 8 mbps from the central server to the client which is called downstream speed. While customers to servers only have speeds between 16 Kbps to 640 Kbps which is called the upstream speed.
Now for people who are unfamiliar with networking or information technology, of course, ADSL modems are not very familiar to their ears, so what’s the difference between this modem and the modems that are commonly used today? for that let’s discuss it in full in the following article.

ADSL Modem Differences And Modems In General
Talking about the differences between ADSL modem and modem in general, we will differentiate them one by one according to the function and role of each type of modem.
This regular modem can be called a cable modem or cable modem which has a difference in the type of cable. For this type of modem uses a twisted pair cable that provides voice and data services. Which cable the cable modem uses is a coaxial cable. For more details, here are the differences between ADSL modems and modems in general.
|Basis for comparison||Modem ADSL||Cable modem|
|The type of fiber used||Twisted pair cable||Coaxial cable|
|Maximum speed offered||200 Mbps||1, 2 Gbps|
|Security||Dedicated connection provides security.||Not safe|
|Additional options||User can choose ISP||There is no such option.|
|frequency range||25 KHz – 1, 1 MHz||54 – 1000 MHz|
The function of the ADSL modem in its use
First, we will discuss what the function of the ADSL modem is, let’s look at the following explanation:
ADSL Modem Picks Up Home Phone For Its Internet Connection
The first function of this modem is to provide an internet connection using a home telephone network. Almost every house that has a telephone cable network can enjoy an internet connection using this ADSL technology.
This technology used to really help homeowners use the internet without the need to make complicated settings. As a customer, usually those who have subscribed to this modem are already included in the package, so they don’t need to install it themselves.
To Split the Delivery Frequency
The second function of this ADSL modem is to share the transmission frequency. If there is a dial up connection, the frequency obtained cannot be shared. It can also create conversations that take place over the phone that cannot be carried out when the client is connected to the internet.
Advantages And Disadvantages Of ADSL Modems
So why is this ADSL modem not being used so much anymore, there are several reasons why modems have advantages and disadvantages, namely:
Advantages of ADSL Modems
Beberapa kelebihan yang dimiliki ADSL yakni:
- Has a fairly high and stable internet speed.
- There is a distribution of two types of frequencies that keep him connected to the internet even though he is on a call or vice versa.
- Voice and data communication services are separated through these two channels but are still in the same cable.
- If you use the internet, then this ADSL can save your internet expenses.
Disadvantages of ADSL Modems
Some of the disadvantages that ADSL has are:
- Distance factor that can affect the speed and stability of the connection. The farther the computer is from the modem, the slower the internet speed will be.
- ADSL modem speed which still depends on the available DSLAM or telephone pole. In addition, not all computer operating systems can use this ADSL technology.
- With the load coils that shift the sound frequency to the frequency normally used by ADSL. This condition also results in interference or obstacles that exist on ADSL lines.
From the discussion above we can conclude that this ADSL modem is a modem technology that is still used today even though it has a speed that is not as fast as today’s modern cable modems. how do you understand the functions and differences between these two modems? if you like articles like this you can read other articles on NetData.
