What is a USB Dongle? How It Works and Its Types

In this era of advanced technology, device limitations are no longer an obstacle. A USB dongle is available if your device lacks Wi-Fi or Bluetooth.

You will be able to stay connected to WiFi or other Bluetooth devices by simply plugging the USB dongle into the USB port of your laptop or computer.

This article will provide extensive information on USB dongles, from their definition, working methods, functions, types, advantages, and disadvantages.

What is a USB Dongle?

A USB dongle is an electronic device shaped like a USB flash drive that serves as an additional tool, ranging from internet connection and Bluetooth to added security. These devices generally work plug-and-play in the USB port of a computer or laptop, although some dongles require a driver to operate.

If your device does not have a Bluetooth feature, you can simply plug in the dongle and connect to wireless devices such as a wireless mouse or True Wireless Stereo (TWS). For computers that do not have a WiFi module, there is also no need to worry; with this device, your computer can be connected to a WiFi network.

How Does it Work?

In simple terms, a USB dongle works as an additional connection on a device that does not have a specific function. Here is how it works in detail:

• Connection: The dongle is plugged into a USB port.
• Driver installation (if required): Some drivers may require driver installation to operate the device, but most dongles are plug-and-play.
• Function activation: Once connected, the dongle activates its functions such as WiFi or Bluetooth.
• Data exchange: Then, as an intermediary, the dongle will exchange data between the device and the network or other devices.

The Types

USB dongles are divided into several types with different functions and uses according to their needs. Here are some types of devices that are commonly used:

1. USB Dongle Wi-Fi

This type of USB dongle is designed for devices that do not come with a Wi-Fi module. By plugging the dongle into your device, your device will automatically have a Wi-Fi module, allowing you to connect to a wireless network.

The Functions 

The USB dongle WiFi has several functions, from connecting devices without built-in WiFi to improving performance. Here are some of its functions:

• Connects devices without built-in WiFi: This dongle allows devices that do not have a WiFi module to connect to a WiFi network.
• Alternative connection: When a wired internet connection is interrupted or unavailable, the dongle can be an alternative solution.
• Improves performance: Some WiFi networks already support WiFi 6, offering higher speed and performance.

2. USB Bluetooth dongle

For devices that don’t have Bluetooth, this USB dongle is for you. By plugging the dongle into your device, you’ll automatically gain Bluetooth functionality, allowing you to connect to other Bluetooth devices such as speakers, TWS earbuds, keyboards, or mice.

The Functions 

The USB Bluetooth dongle has several functions, from adding Bluetooth functionality to acting as a transmitter and receiver. Here are some of its functions:

• Adds Bluetooth function: Acts as an adapter for devices that do not have built-in Bluetooth to connect with other Bluetooth devices.
• Data transfer: Can be used for file transfer between devices.
• As a transmitter and receiver: Works to transmit Bluetooth signals and receive Bluetooth signals.

3. USB Dongle Modem

This USB dongle connects a computer or laptop to the internet via a 3G or 4G cellular network. It works by converting digital signals into analog signals that can be transmitted to the cellular network, and vice versa.

The Functions 

The USB dongle modem has several functions, from mobile internet access to a modem alternative. Here are some of its functions:

• Mobile internet access: Allows users to connect to the internet using mobile networks such as 3G, 4G, or 5G via a SIM card.
• Solution for devices without built-in WiFi: Same as the USB WiFi dongle, as a solution for devices without built-in WiFi.
• Modem alternative: A good alternative for users who need an internet connection when traveling or when there is no WiFi network.

4. TV tuner dongle

A TV tuner dongle is a type of dongle that allows you to watch TV broadcasts from your computer or laptop without the need for a dedicated TV set. This dongle will capture broadcast signals as an external antenna and digital decoder. Analog radio signals will be converted into a format that can be processed by the device.

The Functions 

The TV tuner dongle has several functions, from adding TV features to the device to recording TV shows. Here are some of its functions:

• Add TV features to the device: Allows devices that do not have a built-in TV tuner to still enjoy TV broadcasts.
• Receiving digital TV signals: Serves as an external receiver for digital broadcast TV signals.
• Recording TV shows: Allows users to record TV shows and save them in a digital format.

5. Dongle Software 

Dongle software is a type of dongle that serves to activate software or unlock certain features in software. Some professional software (usually for design or engineering) requires this special dongle for the license to be active. It also serves as a security system.

The Functions 

The dongle software has several functions, from access to software features to authentication. Here are some of its functions:

• Access to software features: Must connect a dongle to unlock full features or specific content of the software.
• Copy protection and software licensing: Can prevent software from being pirated or used without permission by locking certain features.
• Authentication: Authenticates authorized users to access certain software or features.

The Advantages

Here are some advantages of a USB dongle:

1. Flexibility of use

One of the advantages of a USB dongle is its flexibility of use. This device can be used in various devices that have USB ports, such as laptops, computers, and smart TVs

2. Easy to carry

Easy to carry is another advantage of USB dongles. With its small size and lightweight design, it is possible to travel easily. So while traveling, you can stay connected to the internet or access features on the device.

3. Ease of use

USB dongles are generally very easy to use. You simply plug the dongle into your device’s USB port, and the software or drivers will automatically be installed. Or some require installing the driver with a simple wizard.

4. Multiple functions

Despite its small size, a USB dongle comes with multiple functions. Not only are they capable of connecting to the internet, but they can also be used for other purposes, such as Bluetooth connections, adapters for different devices, or access to external devices.

5. No additional power required

Another advantage of USB dongles is that additional power is not required. USB dongles are generally already powered from the USB port where they are attached, so additional power is not required.

The Disadvantages 

Here are some disadvantages of a USB dongle:

1. Taking up USB ports

One of the drawbacks of a USB dongle is that it takes up USB ports. Every device, such as a laptop or a computer, usually has only a limited number of USB ports. By using a dongle, of course, it reduces the USB port allotment.

2. Prone to loss or damage

The small and lightweight design provides advantages in its ease of carrying when traveling. On the other hand, its small size and light weight make the dongle vulnerable to loss or damage if not stored properly.

3. Performance depends on quality

A USB dongle is a device that has performance depending on its quality. To get a dongle with good performance, of course, you have to buy a dongle at a higher price, because cheap dongles usually have poor performance.

4. Limited range

This type of USB WiFi dongle has a limited range, usually shorter. This depends on the size of the antenna on the dongle. Usually, a small dongle antenna will have a more limited range.

Those are the advantages and disadvantages of USB dongles that you can consider before deciding to use them. When you choose to use a USB dongle, you can enjoy the advantages of flexibility of use, ease of use, and no additional power required.
