Let’s Understand Bandwidth Speed, Functions and How It Works!

Bandwidth Speed

Bandwidth Speed – Ever heard of bandwidth? Maybe if you think about it in general and what you’ve ever heard of is internet speed. Is that a description of the bandwidth? Maybe that can’t be justified but can’t be blamed either. So what does bandwidth mean?

So, maybe you often hear about bandwidth, especially when discussing the topic of Virtual Private Server (VPS). However, before going into more detail about bandwidth, let’s get to the surface first.

Before Bandwidth Speed, Let’s Discuss Internet

Bandwidth is closely related to the internet, therefore let’s first discuss what is called the internet. Because indeed the internet is the basis for you to understand what is meant by bandwidth.

Definition of the Internet

The Internet is a worldwide telecommunication system that provides connectivity for millions of smaller networks; therefore, the internet is often referred to as a network of networks. This allows computer users to communicate with each other across distance and computer platforms.

The Internet began in 1969 as the US Department of Defense Advanced Research Projects Agency (ARPA) to provide direct communications within the Department in the event of war. The computers were then installed in US universities with defense related projects. When scholars went online, these networks changed from military use to scientific use. As the ARPAnet grew, system administration was distributed to a number of organizations, including the National Science Foundation (NSF).

This shift in responsibility began the transformation of the science-oriented ARPAnet into the commercially-minded and funded Internet used by millions of people today.

Functions and Purpose of the Internet

The Internet acts as a pipe to transport electronic messages from one network to another. The heart of most networks is the server, a fast computer with a large amount of memory and storage space. The server controls the communication of information between network-connected devices, such as computers, printers, or other servers.

Benefits of the Internet

There are many benefits of the internet that you need to know about, you can get various benefits from the internet and you have even felt it now, including:

Information, Knowledge, and Learning

As previously mentioned, the Internet contains an endless supply of knowledge and information that will allow you to study almost any topic or question you may have.

Connectivity, Communication and Sharing

In the past, it would take days or even months to receive letters from other people. Now, communication can be easier.

Address, Mapping and Contact Information

With the help of GPS technology, the Internet helps to map and direct you to almost every place in the world. You are no longer lost with the internet.

Banking, Billing, and Shopping

The internet provides access to your bank account to view balances, make transactions, and send money. Also, many services allow you to view and pay bills electronically.


The Internet gives everyone access to an endless supply of entertainment, with access to watching videos, watching movies, listening to music and even playing games online.

Internet impact

The internet has a very significant impact. This impact is not always positive, because everything that is created must have a negative impact. The impact of the internet that is felt is where you can get information easily and can make information very broad so that your insight becomes wider.

However, what are the impacts of the internet both positive and negative?

Positive impact

The following are the positive impacts of the internet that you need to know:

  • It provides effective communication using e-mail and instant messaging services to any part of the world.
  • This improves business interactions and transactions, saving important time.
  • Online banking and shopping have made life less complicated.
  • You can access the latest news from anywhere in the world without depending on TV or newspapers.
  • Education has received a major boost as countless books and journals are available online from libraries around the world. This has made research easier. Students can now choose online courses using the internet.
  • Applications for jobs have also become easier as most of the vacancies are advertised online with online applications being the norm.
  • Professionals can now exchange information and materials online, thereby increasing research.

Negative impact

Meanwhile, the negative impacts of the internet that need to be monitored and avoided are as follows:

    • Availability of illegal or inappropriate material online that is not age appropriate.
    • Addiction to social networks can interfere with an individual’s life, both personally and professionally.
    • Some criminals use the internet to hack people’s accounts for fraudulent activities including stealing data or banking information.
  • But others have been known to abuse the internet to spread hatred and terrorism, two dangerous disaster scenarios.

How Does Bandwidth Work?

Now we will discuss about bandwidth, which is the main discussion of this article. How does bandwidth work? Bandwidth type? And also the benefits of bandwidth you need to know.

Get to know Bandwidth

Bandwidth is measured as the amount of data that can be transferred from one point to another in a network in a given amount of time. Usually, bandwidth is expressed as a bitrate and is measured in bits per second (bps).

The term bandwidth refers to the transmission capacity of a connection and is an important factor when determining the quality and speed of a network or internet connection.

How Does Bandwidth Work

The more bandwidth a data connection has, the more data it can send and receive at one time. Conceptually, bandwidth can be compared to the volume of water that can flow through a pipe. The wider the pipe diameter, the more water can flow through it at one time.

Bandwidth works on the same principle. The higher the capacity of the communication link, the more data can flow through it per second.

Bandwidth Type

So, in the IT world, there are two types of bandwidth that you need to know about. The two types are analog bandwidth and also digital bandwidth. What are the differences between the two types of bandwidth?

Analog Bandwidth

The first is the analog bandwidth, which is the bandwidth with the maximum sinusoidal frequency of the analog signal used by the circuit.

Digital Bandwidth

As for the digital circuit bandwidth is different. Than a circuit is less than analog bandwidth because digital signal is made of values 1 and 0 and it is a square wave signal. If you plot a square wave frequency spectrum, the maximum frequency content in the signal is more than the square wave frequency.

Bandwidth Benefits

Having a high bandwidth certainly has very many benefits. When you have high bandwidth, the benefits you can get are as follows:

  • Faster application performance. Today, people want something fast. Higher bandwidth substantially increases the responsiveness of all your website applications.
  • Enables interactivity. Interaction increases user connection and loyalty to the website. Higher bandwidth improves your users’ experience by allowing them to upload and/or download content, such as photos and videos.
  • Improved data transfer capability. Higher bandwidth allows your users to upload and download large amounts of data to your website.
  • Faster data transfer speed. The benefit of website interactivity is negated if uploads and downloads are very slow. Higher bandwidth results in much faster transfer speeds resulting in less frustration and greater customer satisfaction.
  • Allows more concurrent visitors. The more traffic your website can accommodate, the faster it will grow and the bigger your profits will be. Higher bandwidth achieves this goal by allowing multiple visitors at once.
  • Reduces breakage, reflections or “busy signals”. If users are frustrated or unable to access your website within a certain amount of time, you will lose them. Higher bandwidth helps avoid compromising your server resulting in a much smoother experience for your users.
  • Supports multiple concurrent sessions. Users rarely run one application at a time. With higher bandwidth, you enable your users to multitask and maximize their productivity by running multiple applications simultaneously.
  • Stream videos faster. Watching a video that constantly freezes is incredibly frustrating. Higher bandwidth allows your users to focus on your video content instead of distracting distractions.

Function Of Bandwidth

As for the function of the bandwidth you need to know are as follows:

Measuring Data Delivery Media

Bandwidth is very useful in network distribution. This is the main function and the first function of bandwidth that you need to know about. Bandwidth size is usually used as a benchmark for users to choose a provider or service provider related to internet connections. The greater the bandwidth offered, the better the services provided.

Sharing Data Transfer Speed

Bandwidth can be useful as a divider of data transfer rates. This is necessary so that network distribution will be felt fairly for all users. This division is also useful so that each user is not fighting for bandwidth.

Set the amount of data transferred

Bandwidth can also function to reduce high traffic over a long period of time. high traffic for a long time will certainly affect network stability right?

Bandwidth Type Existing On Computer

Computers have their own bandwidth which is useful for being able to transfer data between one user and another, and some also act as a medium for accessing the internet. However, actually what types of bandwidth are there on the computer?

The following are several types of bandwidth on your computer that you need to know:


The first maybe you know this connection. A dial-up connection uses a standard telephone line and an analog modem to access the Internet with a data transfer rate (DTR) of up to 56 Kbps.

A dial-up connection is the least expensive way to access the internet, but it is also the slowest connection.

DSL (Digital Subscriber Line)

Then next is DSL. It is a communication medium used to transfer the internet via copper cable telecommunication lines. Along with cable internet, DSL is one of the most popular ways ISPs provide broadband internet access.

Cable TV

Did you know that cable TV is one of a kind bandwidth? So, in cable TV, the bandwidth that is sent over the cable network is divided into many channels (channels). The width of each TV channel is 6 MHz.

This is because the TV signal is used for TV with a frequency of 6Mhz (NTSC standard) or 7 or 8Mhz (PAL standard), to suit a standard video bandwidth of 4.2 MHz, and HDTV (high definition glass) bandwidth which is compressed to 6 MHz.

Mobile Network

Cellular networks are one of a kind bandwidth. However, many people mistakenly think of mobile bandwidth as internet speed; but of course, the two are completely different. A common metaphor used to make the distinction clear is to visualize water flowing through a pipe.

Several Ways to Optimize Bandwidth Speed

You don’t always enjoy fast data transfer speeds and fast internet bandwidth that you have. But sometimes there are obstacles that make your bandwidth speed decrease, of course this is very annoying right? Nobody wants to surf the internet at a slow speed.

But take it easy, there are several ways to optimize bandwidth speed that you can try.

Use Qos

If you want to limit the amount of bandwidth connected devices can use, if a device is using too much, you can limit it to a percentage of the total available bandwidth. This can be found in Qos in “Expert Mode” under “Settings” then “QoS Control”. By default this feature is disabled.

Use the Cloud

So, using the cloud can also optimize bandwidth speed. Cloud Storage provides bandwidth monitoring for you to track bandwidth usage from your project bucket to your own Cloud service. Typically bandwidth monitoring is aggregated by region and tracks usage for the last 30 days. Bandwidth monitoring is not available for multi-region.

Eliminating Unnecessary Internet Use

This one method is enough to optimize bandwidth speed. For example, there are users whose devices have never connected to your network, you can delete them. Because sometimes this is very annoying. Or there are people who enter your network without your knowledge, you can get rid of them.

Update Backups

Did you know that performing an “update backup” operation can reduce network performance? Yes, backups that are always piled up will add to the burden on storage, therefore, always update backups. You can update backups outside of business hours.

How to Measure Bandwidth Speed

Are you confused about how to measure bandwidth speed? Maybe you are curious about the network you have, how much bandwidth or other cases like you are wondering why the transfer speed is so slow.

The following is an easy way to measure bandwidth speed:

Bandwidth Speed ​​Measure

To start with, Bandwidth is basically measured in bits per second and expressed as bps. However, today’s networks typically have much higher bandwidth than can be comfortably expressed using such small units. It’s now common to see higher numbers denoted by a metric prefix, such as Mbps, (megabits per second), Gbps (gigabits per second), or Tbps (terabits per second).

Using the Speed ​​Test Tool in Internet Browsers

A quick and easy way to get a bandwidth check is to use an internet based speed test. There’s nothing to install and results are available in seconds.

You can find out on the Speedtest.net website or Google Stadia bandwidth speed check.

By Downloading Large Files

If you want real bandwidth speeds, you can download large files. Because basically, this bandwidth test works by downloading and uploading a known amount of data to their servers and then measuring the time it takes. The results (at least you get information about upload speed, download speed and ping).

Using Bandwidth Meter Software

Bandwidth Meter Pro easy-to-use network software for bandwidth usage monitoring, reporting, and notification. The software monitors bandwidth through installed computers, displays real-time graphical and numerical download and upload speeds (see screenshot below), logs bandwidth usage, and provides daily, weekly, and monthly bandwidth usage reports.

What is the Standard Bandwidth Speed ​​for an Activity

Buying an internet package from an ISP must pay attention to the bandwidth speed. Pay attention to your needs, rather than wasting money to pay for an internet package, but the usage doesn’t match what you expect.

These are some standard bandwidth speeds for various activities:

Online Meeting Bandwidth Speed

For online meeting needs, what you need is around 300 Kbps – 2.6 Mbps internet speed. Depending on whether you want to get regular meeting quality or HD.

Movie Streaming Bandwidth Speed

For those of you who often stream movies, this is very important. To be able to watch streaming video smoothly at SD 480p quality, users need an internet speed of 900 Kbps and 3.5 Mbps for HD quality.

Live Streaming Bandwidth Speed

For a content creator who frequently does live streaming, the bandwidth you need is still the same as streaming movies, that is, what you need is around 900 Kbps to 3.5 Mbps. For this, take the highest for good streaming quality.

Gaming Bandwidth Speed

For those of you who like to play games, especially online games, connectivity with a bandwidth of 25 Mbps can be the best choice. This alternative can also fulfill the prerequisites if the speed can be used to do various things such as streaming as well. It’s just that, even then, if the minimum upload speed is 5 Mbps.

Bandwidth Download / Upload File Speed

For those of you who often download files and also upload files, the recommended bandwidth is as follows:

  • File size of 1 GB with a speed of 8 Mbps (8 Mbit/s) is equivalent to 1MByte/s for 17 minutes 53 seconds.
  • File size of 1 GB with a speed of 10 Mbps (10 Mbit/s) is equivalent to 1.25 MByte/s for 14 minutes 18 seconds.
  • File size of 1 GB with a speed of 100 Mbps (100 Mbit/s) is equivalent to 12.5 MByte/s for 1 minute 25 seconds.
  • File size of 1 GB with a speed of 300 Mbps (300 Mbit/s) equivalent to 37.5 MByte/s for 28 seconds.

Calculating Bandwidth Speed Needs for an Office

So, there is a separate way to calculate bandwidth speed requirements for an office. A simple system for calculating bandwidth requirements is by:

  • The assumption is that 1 staff implements 1 internet-connected device
  • Group staff in the office based on bandwidth requirements, type of professional duties for which they are responsible:
    • LIGHTWEIGHT Users: 50Kbps (applies World e.g. only for e-mail or browsing)
    • MEDIUM Users: 80Kbps (using Dunia for example for info system administration, accessing cloud-based methods, image/video files but sending per batch, downloading files regularly, etc.)
    • HEAVY Users: 120 Kbps (apply World routine for Big files and Real Time e.g. CCTV, video conferencing, high resolution images, VoIP telephony methods, online Screen services, desktop sharing and more)


Bandwidth is indeed a very crucial thing if you expect good data transfer and internet speed. Therefore, it is important to pay attention to how much bandwidth you need.
