WiFi vs Bluetooth: Difference and Comparison

The world has digitalized, and communication has switched to wireless forms. Every device that we use is equipped with wireless capabilities.

The two most important wireless forms in every device are WiFi and Bluetooth. Both forms have different functions and capabilities.

Key Takeaways

  1. Wi-Fi enables internet access over longer distances, while Bluetooth connects devices over shorter distances for data transfer.
  2. Wi-Fi has higher data transfer rates than Bluetooth, which makes it ideal for larger data transfers and streaming.
  3. Bluetooth consumes less power than Wi-Fi, making it more suitable for battery-operated devices and low-energy applications.

WiFi vs Bluetooth

Wi-Fi is a type of communication technology used for high-speed internet connectivity and local area networking over longer distances. Bluetooth is a type of communication technology used for short-range wireless connections between devices for data transfer, audio streaming, etc.

WiFi vs Bluetooth

Wi-Fi works on radio waves for the transfer of high-speed data. It breaks the signal into pieces and transmits the fragments.

The technique used helps in transmitting the signal at a lower power per frequency and allows multiple devices to be connected simultaneously.

On the other hand, Bluetooth operates on radio signals. Bluetooth doesn’t provide web access or the Internet but is mainly used for sharing information.

For functioning, Bluetooth requires only an adapter, and the connectivity of the device is. It consumes low power. Bluetooth can provide a range of radio signals of about 10 meters. Hence all the devices need to be in close contact with each other.

What is WiFi?

Wi-Fi stands for wireless fidelity. It is a wireless networking technology that connects different types of devices to the Internet.

It is based on IEEE 802.11.WiFi is commonly used within a specific local area for connecting devices across the Internet. The exchange of data within the connected devices occurs through radio waves.

The most common application of Wi-Fi is in the home, officers, coffee shops, schools, libraries, hotels, airports, and other public and personal spaces.

The devices are connected to a wireless router which connects them to the Internet. The device’s network through wireless access points.

Wi-Fi was first introduced on 21st September 1997. The term WiFi was coined by a brand consulting firm Interbrand.

Various WiFi versions are available depending on the radio technology, radio band, maximum range, and protocol standards each type uses.

The two most common radio bands Wi-Fi uses are 2.4 GHz which is 120 mm UHF, and 5 GHz, 60 mm SHF.

The wavebands of Wi-Fi can be obstructed through walls, appliances, or pillars, which can affect the range and cause minimizations in the interference of the connected network.

The maximum access offered by WiFi indoors is about 20 meters, while some modern access points even provide arranged up to 150 meters and are installed outdoors.


What is Bluetooth?

Bluetooth is a part of wireless technology, which is used for exchanging data within a short range. The data exchange occurs within fixed and mobile devices by using UHF radio waves in the ISM bands.

The band’s range is between 2.4 GHz to 22.48 GHz. Bluetooth formed the basis of personal area networks or PANs. Initially, Bluetooth was built as an alternative to RS-232 data cables.

Bluetooth is used to exchange files between portable devices. The transmission power is mostly 2.5 milliwatts and can range only within 10 meters or 30 feet.

Bluetooth was developed by the Bluetooth Special Interest Group (SIG) and introduced on 7th May 1998.

The term Bluetooth was coined by Jim Kardach, who was working at Intel the name was taken as an inspiration from a historical novel by France G Bengsston.

The logo of Bluetooth has a bind ruin merging with the younger food truck ruins and forming a shape which is the initials of Harald’s.

The most compatible hardware with Bluetooth is personal computers, gaming consoles, smartphones, audio devices, and several other smart devices.

Various versions of Bluetooth are used depending upon the need of the place, as the versions provide a different range of connectivity.

According to a survey in 2019, over 3.6 billion Bluetooth devices were being shipped annually, and the graph seemed to increase at the rate of 12% a year.
