Bluetooth vs Wifi
Bluetooth and WiFi are different standards for wireless communication.
Bluetooth technology is useful when transferring information between two or more devices that are near each other when speed is not an issue, such as telephones, printers, modems and headsets. It is best suited to low-bandwidth applications like transfering sound data with telephones (i.e. with a Bluetooth headset) or byte data with hand-held computers (transferring files) or keyboard and mice.
Wi-Fi is better suited for operating full-scale networks because it enables a faster connection, better range from the base station, and better security (if configured properly) than Bluetooth.
|Improve this chart||Bluetooth||Wifi|
|Frequency:||2.4 GHz||2.4, 3.6, 5 GHz|
|Security:||It is less secure||It is more secure|
|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|
|Bandwidth:||Low ( 800 Kbps )||High (11 Mbps )|
|Specifications authority:||Bluetooth SIG||IEEE, WECA|
|Year of development:||1994||1991|
|Primary Devices:||Mobile phones, mouse, keyboards, office and industrial automation devices||Notebook computers, desktop computers, servers, TV, Latest mobiles.|
|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.|
|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.|
