Bluetooth is a way of exchanging data wirelessly over short distances, and is an attempt to do away with your computer’s jungle of wiring. Using a special radio frequency to transmit data, it creates a short range network.
Bluetooth is designed to reach short distance to pair devices
Provides a cable free connection between multiple devices
Does not need access to internet to pair devices
Runs on a 2.4Ghz frequency
Runs a low bit rate of 2.1 Mpbs
Supports keyboards, headsets, keychains, mouses, and even toothbrushes
Wifi is a technology that uses radio waves to provide network connectivity. A connection is established using a wireless adapter to create hotspots-areas in the vicinity of a wireless router that are connected to the network and allow users to access internet services. Once configured, WiFi provides wireless connectivity to your devices by emitting frequencies between 2.4GHz - 5GHz, based on the amount of data on the network.
WiFi provides high speed access to the internet
WiFi is designed to be able to access the internet from a short distance all the way up to distances roughly around 300 feet away
It can run a bit rate of about 600Mbps
It supports computers, smart phones, TVs, gaming consoles, and many more devices that access the internet
The security for WiFi is much better than that of bluetooth
