Rate this post

In the world, the use of broadband is growing more and more, so it may cause us great concern to know, what this is, and how it works. Many of us may even be using a connection and not know that we are doing it.

Today we will learn all about bandwidth and how to use it. And so that we don’t get confused between broadband and narrowband or fiber connection we bring you some sections that show us the differences it has.

We can also measure the speed of our connection, by following the steps below. These steps are quite simple and short.


What is broadband and what is this type of Internet connection for?

This concept can vary a lot, but in the area of telecommunications a network connection with a high speed of information sharing is known as broadband, where the speed with which the information is transmitted is very important.

In other words, we can say that the bandwidth is that connection where data are transmitted symmetrically so several pieces of information are sent simultaneously.

So a connection with two or more simultaneous data channels is called multiplexing , most broadband connections are offered by “Fiber to the home” services , which means fiber to the home , operated by routers, whose speeds are greater than 100 Mbps.

In short, anything that operates at symmetrical transmission speeds is known as a broadband connection. This concept has evolved in the world , as it implements a method to extend the speed. For example, ISDN with 128 Kbps gave way to SDSL offering a speed of 256 Kbps , then evolved, changing from 25 to 50 Mbps symmetrical until today offering more than 600 Mbps .

How does a high-bandwidth Internet connection work?

We have to understand that, when we talk about a broadband Internet connection, we mean a system that uses multiple data channels, whose function is to send information to the various subscriber networks.

When we implement this type of connection it is specifically known as a connection that is always active, because the technology implemented for Internet access remains constantly connected, is not interrupted and does not block phone lines.

We, as broadband Internet users, can connect quickly to the Internet, unlike other connections, we do not have to connect to the network again after we log out and thus avoid experiencing delays in data, information or large content transmission.

In many countries the connection is used, so some types of this connection, influence different digital subscriber lines (DSL), as:

  • Fiber optics.
  • Wireless connection.
  • Satellite.
  • Broadband connection through power lines (BPL).

But despite the above we must take into account that although in most cases DSL connections are considered to be bandwidth , not all of them can be. One of the characteristics of a broadband Internet connection is that it transmits a communication bandwidth of about 256 Kilobits per second minimum .

From the definition of bandwidth we can define two more concepts: mobile broadband and wireless broadband . When we refer to mobile bandwidth we mean that it is a connection that allows us a connection for mobile devices.

On the other hand, the wireless band connection works in a similar way, although providing a high speed connection, for different areas covering a certain range.

Broadband and Narrowband How are they different?

When we talk about a narrowband connection, we mean that is a dial-up connection , it has a maximum data download speed of 56 kilobits per second , unlike broadband, which has a maximum data download speed of 256,512 or more kilobits per second .


In other words, a narrowband connection, means that one less amount of data flows per second, while the bandwidth offers a higher download and upload connection. To make things a little more redundant, narrowband offers a narrower transmission path, while broadband is wider.

Differences between optical fiber and broadband network

A transmission medium commonly used in data networks is called an optical fibre . It is made of a transparent glass or plastic thread, through which pulses of light are sent representing the data being transmitted.

The light beam remains confined and spreads through the fibre core with a reflection angle that is above the limit angle of a total reflection.

These are mostly used in large telecommunications , as they have the ability to send a lot of data from a long distance, with a speed similar to that of radios. This is the best means of transport for the transformation of information since are immune to electromagnetic interference .


Advantages of this connection

  • Good network speed
  • Zero problems with connection drops

Connection disadvantages

If the router does not have the connection you hired, because the connection is different, if it breaks down it may not be recognized by another one.


As we have already seen, the bandwidth connection can still offer us more connection, because the connection can be wireless, or via satellite. While the fiber connection should be primarily through a transparent thread .

Although each one has different advantages, there are some characteristics that make them very similar with respect to their behavior, especially in the speed of sharing information .

What is the average speed of a broadband Internet connection?

The idea of an Internet connection and the average speed study has been implemented for many years. M-Lab was a project that emerged thanks to the collaboration of different recognized entities, such as Google and Princeton University. Where they measured the average connection speed, in the world in 2018.

To achieve this, implemented a study of over 160 million speed tests, which were conducted over 12 months in 200 countries, where it was determined that the bandwidth connection is constantly growing.

The study showed that there was a very noticeable increase. Higher than 2017, where showed an average speed of 9.10 Mbps, being 20% higher than the last study (carried out in 2017, which obtained 7.40 Mbps)

Many of the telecommunication companies look at these studies to try to maximize their connection speed, where notoriously in 2019 many countries have increased in a qualitative way the speed position of the Internet.

Steps for measuring the speed of your broadband network easily and quickly (speed test)

Through the following link we can measure the connection speed of our network. But first we must know that we need to be connected to the network which we want to know what its speed is.

To achieve this we only need to complete the following steps:

  • Step 1: We connect directly from our Internet port.
  • Step 2: Let’s close all those applications that are running in the background.
  • Step 3: We start the Test. To do this we give in the speed test

What is multiplexing in bandwidth networks?

Telecommunication multiplexing, is known as the procedure by which different information shares data through the same channel. This process involves an extraction of a certain signal, which locates a communications channel which is defined as demultiplexing.

What is multiplexing?

This refers to an ability to allow a transfer of data coming from different devices, known as transmitters and receivers, also called low-speed channels from a physical medium, otherwise known as high-speed channel .


A multiplexer is those multiplexing devices that combine the signals from the transmitters and are sent through a high or medium speed channel.

Types of multiplexing

Multiplexing has different forms and types, which are classified in this way:

  • Time domain.
  • Frequency domain.
  • By code.
  • Wavelengths.

This term is mostly used in the field of communications, thus allowing a wide development of technology. This term has allowed the study of connection speeds and the number of channels that exist between each network, so its term is related to that of bandwidth.
