What is Bluetooth?

Bluetooth allows you to transfer data from one electronic device to another over short distances.

For instance, you can use Bluetooth to connect your laptop to wireless headphones. Your Bluetooth connection will allow the sound data from your computer to transfer to your headphones.

It also allows you to transfer files from one device to another.

Similar to WiFi, Bluetooth uses radio waves to transfer signals. Therefore, the radiofrequency of Bluetooth is the same as that of WiFi.

This can occasionally cause interference issues.

Connecting to Bluetooth is a lot easier than connecting to WiFi.

All you need to do is turn on the Bluetooth on your wireless device and then turn on the Bluetooth search on the other device. Then, when you see the name of your wireless device, click and confirm to pair the two.

Almost all current devices now come with Bluetooth technology built into the system. This makes it easier for you to connect to accessories and devices like wireless keyboards, wireless headphones, gaming consoles, Bluetooth speakers, etc.

What is WiFi or Wireless Communication?

WiFi also allows for wireless communication over radio signals. However, Wi-Fi will enable you to access the internet rather than forming a connection to transfer data.

Access to WiFi is usually provided through a WiFi router connected to a local area network (LAN).

Earlier, people would use LAN cables to connect their computers to the internet. However, with WiFi technology, you don’t have to worry about getting tangled up on wires.

You need to search for your Wi-Fi SSID, then enter your password, and you’re all set to surf the internet.

As mentioned earlier, WiFi uses the same radio wave frequency as Bluetooth, which may, in some rare instances, cause interference.

WiFi signals travel over longer distances than Bluetooth signals. Although, the speed and quality of your WiFi network are dependent on your network provider and router.

What is the Difference Between Bluetooth Devices and WiFi Devices?

Now that we’ve discussed both technologies separately, it’s time to talk about the two in comparison to one another.

Here are some of the main differences we found between Bluetooth and WiFi:

  • First, Bluetooth has a lower bandwidth requirement than Wi-Fi. In simple words, Bluetooth can transfer less data/information to the paired device than Wi Fi.
  • Bluetooth signals can travel over short distances only. Their signal range is usually 10 meters. In contrast, WiFi signals can cover more distance and go up to 100 meters.
  • Using and connecting to Bluetooth devices is quite simple. However, connecting to WiFi networks is a bit more complicated. You may need to configure software and hardware settings.
  • Most devices come with built-in Bluetooth technology. If your device doesn’t, you can always get a separate Bluetooth adapter. To access Wi Fi through your device, you will need a WiFi router and adapter.
  • The frequency range for Bluetooth devices is between 2.4 GHz to 2.483 GHz. On the other hand, the WiFi frequency range is between 2.4 GHz.
  • Bluetooth consumes less power on your device in comparison to Wi Fi.
  • Bluetooth is a lot less secure than Wi Fi. However, you can choose from multiple encryption methods for WiFi to add more security to your network.
  • Bluetooth technology is less flexible in comparison to Wi Fi. It allows for only a limited number of users to connect. In contrast, Wi-Fi networks can enable multiple users to access the internet. Some routers may have a set limit for how many users can connect at a time. However, this varies from user to user.

Can I Use Bluetooth Without WiFi?

Yes, you don’t need access to WiFi to use Bluetooth. The two features work independently of one another.

You don’t need to be connected to the internet to connect a wireless device to your laptop or phone using Bluetooth.

Just make sure you have Bluetooth enabled on both of your devices.

Can I Use Bluetooth and Wireless Router Together?

IS it possible to use both WiFi and Bluetooth on WiFi-enabled devices?

Well, you can. However, as we mentioned earlier, Bluetooth and WiFi share the same radio signal range.

You may come across some interference with your Bluetooth and internet signal if you use both together. Although, it’s not a common occurrence.

It would be best to disconnect your wireless speakers if you are facing connectivity issues.

Also, another disadvantage of using both features is that your device’s battery drains a lot faster.

Conclusion

Both WiFi and Bluetooth allow for easy and convenient communication. Wi-Fi enables you to connect to the internet, while Bluetooth makes sharing data reasonably simple.

However, there is some difference between WiFi and Bluetooth. The former allows you to access the internet, while the latter will enable you to transfer information from one device to another.

You can easily use the two features together, although be careful of any interferences.

If you’re having trouble setting up a Bluetooth or a WiFi connection, please refer to our guides for easy instructions and helpful advice.

Difference between WiFi and BlueTooth

Both WiFi and Bluetooth are wireless technologies that are widely used to send and receive data wirelessly using radio signals. WiFi is for high-speed Internet access that connects nearby devices with each other and share the Internet via hotspots, whereas Bluetooth is used for connecting devices in short range.

Go through this article to find out more about the features of WiFi and Bluetooth and how they are different from each other.

What is WiFi?

WiFi stands for Wireless Fidelity. It defines any network based on the 802.11 standards, allows computers and devices with the required wireless capacity to communicate via radio waves with other computers or devices. IEEE established the 802.11 network standards, which describe how two wireless devices interact over the air.

WiFi is a small network where smartphones, computers or other networkable devices are connected to each other wirelessly within a small range and share Internet using hotspots. WiFi uses radio frequency waves for wireless high-speed Internet and network connections. The size of a WiFi antenna is very small and can be put on small routers. WiFi can be used to connect printers, computers, gaming consoles, mobile and so on.
