Here is a simple overview of what is the main difference between Bluetooth and Wireless, and where each of them is being commonly used. Just one of the biggest differences is in the signal range power, frequency, and power consumption.
Bluetooth is commonly used in smaller devices such as older mobile phones or wireless headphones, and on the other hand, wi-fi is better for internet connections and sending the larger portions of data.
|Frequency||2.4 GHz||2.4, 3.6, 5 GHz|
|Bandwidth||Low ( 800 Kbps )||High (11 Mbps )|
|Specifications authority||Bluetooth SIG||IEEE, WECA|
|Security||It is less secure||Security issues are already being debated.|
|Year of development||1994||1991|
|Primary Devices||Mobile phones, mouse, keyboards, office and industrial automation devices. Activity trackers, such as Fitbit and Jawbone.||Notebook computers, desktop computers, servers, TV, Latest mobiles.|
|Hardware requirement||Bluetooth adaptor on all the devices connecting with each other||Wireless adaptors on all the devices of the network, a wireless router and/or wireless access points|
|Range||5-30 meters||With 802.11b/g the typical range is 32 meters indoors and 95 meters (300 ft) outdoors. 802.11n has greater range. 2.5GHz Wi-Fi communication has greater range than 5GHz. Antennas can also increase range.|
|Ease of Use||Fairly simple to use. Can be used to connect upto seven devices at a time. It is easy to switch between devices or find and connect to any device.||It is more complex and requires configuration of hardware and software.|
