is for resident equipment and its applications and is intended as a replacement for cabling for general local area network access in work areas. The category of applications is outlined as WLAN, the wireless local area networks.
Wi-Fi is a trademark of the Wi-Fi Alliance for certified products based on the IEEE 802.11 standards. This certification warrants interoperability between different wireless devices.
Wi-Fi is often used for wireless internet (WLAN ), but actually every product does not have the Wi-Fi certification and hence not all WLAN's are Wi-Fi.
Wi-Fi is supported by most personal computer operating systems, many game consoles, laptops, smartphones, printers, and other peripherals.
Through interconnected access points (hotspots) Wi-Fi can lead to connectivity over large square miles of area, though a typical Wi-Fi home router has a range of 32 m indoors and 95 m outdoors.
Bluetooth is an open wireless protocol for exchanging data over short distances from fixed and mobile devices, creating personal area networks (PANs).
Bluetooth is intended for non resident equipment and its applications. The category of applications is outlined as the wireless personal area network (WPAN). Bluetooth is a replacement for cabling in a variety of personally carried applications.
Bluetooth has a range of less than 10m for gadegts we use (class II device), but it can go upto 100m (class I device). The current version of Bluetooth is 2.1
Next version Bluetooth 3.0 (codename Seattle ) is expected to be released this year which will allow use of Bluetooth over UltraWideBand ( UWB) radio, and data transfer upto 480 Mbit/s.
I guess it's enough for the day. Now we can keep an eye on the future developments in Wireless Connectivity in a more informed way !!
