There are many short range wireless technology exist in today’s scenario.In short range wireless technology 1)Wi-Fi 2)Bluetooth 3)Zigbee 4)NFCBLUETOOTH : a standard for the short-range wireless interconnection of mobile phones,computers, and other electronic devices.–> Bluethooth is a wireless technology is enables you to create a wireless connection between two devices–>Bluetooth topology is referred to as a scattered ad-hoc topology.
It defines a small cell called Piconet which is a collection of devices connected in an ad-hoc fashion.–> “Bluetooth technology was named after a Danish king, King Harald Blatand, who had a penchant for snacking on blueberries and was known for uniting warring factions in what is now Denmark, Norway and Sweden in 1994.–>Bluethooth technology for connecting their smartphone or computer with an audio device for wireless audio transmission Wi-Fi : a facility allowing computers, smartphones, or other devices to connect to the Internet or communicate with one another wirelessly within a particular area.
–> In 1991, NCR Corporation with AT&T Corporation invented the precursor to 802.11, intended for use in cashier systems. –>The first wireless products were under the name WaveLAN. They are the ones credited with inventing Wi-Fi.–> Wi-Fi is a wireless technology that allow to provide network connectivity.–>A WiFi 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.
***DIFFERENCE BETWEEN BLUETHOOTH AND WI-FI ***–>The main difference is that Bluetooth is primarily used to connect devices without using cables, while Wi-Fi provides high-speed access to the internet. Bluetooth is a wireless technology standard that is used to exchange data over short distances (less than 30 feet), usually between personal mobile devices–>They both bluethooth and Wi-Fi is both used to connect devices without using cables.–>Bluethooth is a wireless technology they used to exchange data over a short distances(lesss than 30 feet).–>when wi-fi allows you to transfer the network over there.wi-fi allows you to transfer data at 50 meters(160 feet)or less but is a grater than a bluethooth.–>Bandwidth of bluethooth is low when bandwidth is high.–>In bluethooth security is less comparatively wi-fi.–>When power consumption of bluethooth is low when for wi-fi is high.–>Frequency range of bluethooth is 2.400 GHz to 2.483 GHz whenfrequency range of wi-fi is 2.4 GHz and 5 GHz.–>bit-rate of bluethooth is 2.1 Mbps when of wi-fi is 600 Mbps.
