Difference Between Bluetooth and Wi-Fi

Difference Between Bluetooth and Wi-Fi

Last Updated on by Daniel Lawrence

Both Bluetooth and Wi-Fi are utilized for giving wireless correspondence through radio signs. The most qualification among Bluetooth and Wifi is that Bluetooth is really acclimated interface short-range gadgets for sharing data while Wifi is utilized for giving fast web access or web. Wifi gives high data measure on the grounds that the speed of the web is an imperative issue.

Let’s get to know the difference between Bluetooth and Wi-Fi with the chart below:

NO Bluetooth Wifi
1. Bluetooth has no full form. While wifi stands for Wireless Fidelity.
2. It requires a Bluetooth adapter on all devices for connectivity. Whereas it requires a wireless adapter on all devices and a wireless router for connectivity.
3. Bluetooth consumes low power. while it consumes high power.
4. The security of Bluetooth is less in comparison to wifi. While it provides better security than Bluetooth.
5. Bluetooth is less flexible means these limited users are supported. Whereas wifi supports a large number of users.
6. The radio signal range of Bluetooth is ten meters. Whereas in wifi this range is a hundred meters.
7. Bluetooth requires low bandwidth. While it requires high bandwidth.

Definition of Bluetooth

Bluetooth is an open detail (all-inclusive) for short-range remote voice and data interchanges. Creators of Bluetooth are Ericsson, Nokia, IBM, Toshiba, and Intel framed a Special Internet Group (SIG) to extend the idea and to build up a standard under IEEE 802.15 WPAN (Wireless Personal Area Network). Bluetooth is the principal far and wide innovation for a short-range impromptu network that is intended for joined voice and information applications.

Contrasted and Wifi, Bluetooth has a decreased information rate. Be that as it may, it has an inserted instrument to help the application. Bluetooth is an economical individual territory specially appointed network working in unlicensed terrains and claimed by the client.

Bluetooth SIG involves three applications based scenario

  • Cable replacement
  • Ad-hoc personal network
  • Integrated Access Points (APs) for data/voice.

Definition of Wifi

Wi-Fi (Wireless Fidelity) is the name given by the Wi-Fi Alliance to the IEEE 802.11 suite of guidelines. 802.11 characterized the underlying norm for wireless neighborhood), IEEE details are remote guidelines that characterize an interface that uses the vehicle for communicating and accepting signs between a remote customer and a station or passageway, just as among remote customers.

The point of the 802.11 norms was to create a MAC and PHY layer for remote networks for lasting, convenient, and versatile stations inside a neighborhood.

IEEE 802.11 standard involves the following special features:

  • It provides an asynchronous and time-bounded delivery facility.
  • It supports continuity of service within extended areas via a distribution system.

Requirements of IEEE 802.11

  1. Single MAC is supporting multiple PHYs’.
  2. Mechanisms to allow multiple overlapping networks in the same area.
  3. Provisions to manage the interface from other ISM-based radios and microwave oven.
  4. Mechanisms to manage “hidden” terminal.
  5. Options to support time-bounded services.
  6. Provision to handle privacy and access security.


Bluetooth and Wifi, the two advances were imagined to empower wireless correspondence between different gadgets. However, both have various purposes, enjoy their general benefits and inconveniences. Fundamentally, Bluetooth considered as a brief distance remote correspondence while Wifi gives more advantages and a long-range, enormous number of clients, and practical approach to associate with the web.
