Difference Between Bluetooth And Wifi In Tabular Form
BLUETOOTH
Bluetooth is a wireless technology standard for exchanging data over short distances from fixed and mobile devices, and building personal area networks (PANs).
Invented by Dutch electrical engineer Jaap Haartsen, working for telecom vendor Ericsson in 1994,it was originally conceived as a wireless alternative to RS-232 data cables..
WiFi
Wi-Fi is the name of a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. A common misconception is that the term Wi-Fi is short for “wireless fidelity,” however this is not the case. Wi-Fi is simply a trademarked phrase that means IEEE 802.11x.
The “Father of Wi-Fi,” Vic Hayes is senior research fellow at Delft University of Technology in Delft, Netherlands. From its inception in 1990 through 2000, Mr. Hayes chaired the IEEE standards workgroup that defined the IEEE 802.11 set of wireless networking standards, better known as Wi-Fi.
