Have you heard the word bandwidth? Maybe you are already familiar with the word bandwidth, especially when you want to buy an internet package, it usually says this or that bandwidth. Be it internet for your own home i.e. Wi-Fi or you are using mobile internet network. When buying a data package, it must say how much bandwidth it has, especially for unlimited internet packages.

However, the question is actually what is internet bandwidth? How does the bandwidth itself work? And of course, what are the functions of bandwidth on an internet network? Let’s find out!

Bandwidth can be explained easily actually. Bandwidth is the frequency range that can pass through a particular transmission channel. Bandwidth determines the rate at which information can be transmitted through a circuit: the greater the bandwidth, the more information can be sent in a given amount of time.
Bandwidth is usually measured in bits per second. Increasing the potential for bandwidth has become a high priority for network planners due to the growth of multimedia, including video conferencing, and the increasing use of the Internet.
Bandwidth can also be described as the signal-to-noise ratio (SNR) of the modulated signal tested in the frequency range on both sides of the carrier frequency. This range is also called bandwidth. In the case of videodiscs, it’s often 15 kilohertz (kHz) on either side.
Bandwidth has several functions that you need to know, including:
Data Transfer Media Size
Bandwidth in a network refers to how much digital data we can send or receive over a link in a certain period of time. It is also referred to as the data transfer rate. Most of the time, bandwidth refers to maximum throughput, and the amount of data transferred is measured in bits per second. Bit is the smallest unit of digital data, and is represented by 1 or 0.
Sharing Data Transfer Speed
Another function of bandwidth is useful for dividing data transfer rates. So, bandwidth has a function to distribute internet speed fairly to all users. This division is of course useful so that users do not fight over internet speed so that it can be limited.
Set the Transferred Data Amount
Network administrators occasionally exercise control over large amounts of data that can be accessed or downloaded from the internet. This aims to reduce high traffic in the long term. High traffic for a long time can also disrupt network stability because it affects the available bandwidth capacity.
Bandwidth Example on a Computer
If you are still confused about what computer bandwidth is, so far there are two examples of computer bandwidth, including analog and digital bandwidth.
Analog bandwidth is the maximum sinusoidal frequency of the analog signal used by the circuit.
In analog design the concept of bandwidth as you all know is related to the frequency at which the output will drop its power by 1/2 maximum.
But the digital bandwidth of a circuit is different.
The digital bandwidth of a circuit is less than the analog bandwidth because digital signals are made of the 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.
Tips for Optimizing Bandwidth
Maybe if you already have internet at home, sometimes you experience problems where the bandwidth you buy is actually large, but it doesn’t work as it should. This could possibly happen due to several factors.
However, don’t worry, the distribution of internet speed can be more stable and optimal with the following ways of optimizing bandwidth:
QoS bandwidth management allows you to control the flow of traffic on the network so that traffic does not exceed network capacity (resulting in network congestion) and also allows you to allocate bandwidth for specific types of traffic and for applications and users. With QoS, you can apply bandwidth to traffic on a narrow or broad scale.
QoS profile rules allow you to set bandwidth limits for each QoS class and the combined total bandwidth for all eight QoS classes. As part of the steps for configuring QoS, you can attach QoS profile rules to physical interfaces to apply bandwidth settings to traffic leaving that interface.
Individual QoS class settings are applied to traffic that matches that QoS class (QoS class assigned to QoS Policy rules) and the overall bandwidth limit for the profile can be applied to all cleartext traffic, specific cleartext traffic originating from the source interface and source subnets, all tunneled traffic, and individual tunnel interfaces.
Using the Cloud
Of course, if you want more stable bandwidth, you can use cloud technology. Without a cloud service, companies handle their own workload. Internet connections exist primarily for email, web navigation, and e-commerce, so from a bandwidth perspective, the focus is on the core of the network where the heavy lifting happens. Deploy the fattest pipe and robust infrastructure at its core, and you’re good to go.
Eliminate Unnecessary Internet Activity
The latter, which is a very easy way, is to eliminate unnecessary internet activity. Usually, in one room you can see if there are lots of users connected to one network. The more users that are connected, the bandwidth will automatically be distributed to more IP addresses resulting in a slow network.
It’s a good idea to disconnect the internet network on the connected device if it’s not too important.
Day by day, the bandwidth that is offered to us is getting higher. It is also undeniable that the need for large bandwidth is a priority today, especially if the subscription fee is affordable.
