What is USB Bluetooth?

Bluetooth is a facility that allows for sharing of data between various devices. This data could be in the form of images, contacts, etc. It is a wireless technology that has a limited range that varies from two to a hundred meters or so.

Most of the computers and laptops today have an in-built Bluetooth service.

The devices that lack this pre-existing facility can avail it by using a small hardware device termed as USB Bluetooth. It is a small chip-like card that is plugged into the USB port provided in the device. This enables the device to connect with other devices possessing Bluetooth facilities.

This hardware device allows for wireless communication on one’s device. It is extremely small. This makes it exceedingly easy to carry and handle. It helps in transferring files, music, and various other data across multiple devices. All this is possible without the need for any cables or wires.

USB Bluetooth adapters are very easily available and are cost-efficient. Any kind of external supply or connection is not required for using a Bluetooth adapter. Depending upon the range they can cover and certain other factors, they come in a variety of standards, such as v1.0, v2.0, and so on.

What is Wi-Fi Adapter?

Wi-Fi is a technology that provides better connectivity to devices like laptops, computers, etc. It is a wireless service intended to serve customers with high-speed internet connectivity. It allows for the give and takes of data through radio waves amongst a plurality of devices.

 Unlike Bluetooth, Wi-Fi is not usually in-built in devices, especially desktops. For this reason, Wi-Fi adapters are used to provide wireless connectivity. It is also called wireless Ethernet.

It is easy to use and hassle-free as it replaces wires and cables. It is exceedingly convenient to carry owing to its compact size. Yet another name for a Wi-Fi adapter is dongle.

It is a hardware device that is inserted in the USB port available in the device. It works as a radio transceiver. With the help of radio waves, it transfers data from the router to the devices that have the facility of Wi-Fi enabled.

Wi-Fi adapters aren’t extremely expensive and hence can be used efficiently. They are widely used across the globe, so they are easily accessible. Like USB Bluetooth, Wi-Fi adapters come in a wide variety of ranges.

Therefore, they must be chosen according to the type of device they are going to be plugged into.

Main Differences Between USB Bluetooth and Wi-Fi Adapter

  1. USB Bluetooth serves to provide connectivity amongst other devices and allows sharing of files and data, whereas Wi-Fi Adapter gives high-speed internet connectivity to a particular device.
  2. Both are hardware devices that can be plugged in and used, but the former is usually used less as Bluetooth comes built-in in most of the devices while the latter is widely used.
  3. USB Bluetooth allows the exchange of data such as images, contacts, music, etc., whereas Wi-Fi is generally used to obtain internet facility.
  4. By providing its service to a single device, USB Bluetooth allows connection with other devices possessing Bluetooth facility, whereas a Wi-Fi adapter provides internet services only to the device that it gets connected to.
  5. USB Bluetooth is comparatively more compact as compared to a Wi-Fi adapter which is also at times called a dongle.
  6. While Bluetooth is a facility that was first discovered in 1989, Wi-Fi service was introduced comparatively later. Its launch date fell somewhere in 1998.
