Uses direct-sequence spread-spectrum technologyĨ02.11gExtension of 802.11b, with the same disadvantages (security and interference) Has 11 channels, with 3 non-overlapping, and supports rates from 1 to 11 Mbps, but realistically about 4-5 Mbps max Limits to the number of access points in range of each other, three Uses frequency division multiplexing technologyĨ02.11bBeen around the longest, well-supported, stable, and cost effective, but runs in the 2.4 GHz range that makes it prone to interference from other devices (microwave ovens, cordless phones, etc) and also has security disadvantages Has 12 channels, 8 non-overlapping, and supports rates from 6 to 54 Mbps, but realistically about 27 Mbps max Runs in the 5 GHz range, so less interference from other devices IEEE create standard but Wireless Ethernet Compatibility Alliance certifies productsĨ02.11aCompletely different from 11b and 11g.įlexible because multiple channels can be combined for faster throughput and more access points can be co-located IEEE modified the standard in 1999 to include 802.11 a and bĨ02.11b equipment first available, then a, followed by g Specifications for standard ratified in 1997 Wi-Fi is a wireless technology that uses radio frequency to transmit data through the airīrief HistoryIEEE (Institute of Electrical and Electronics Engineers) established the 802.11 Group in 1990. Short for wireless fidelity and is meant to be used generically when referring to any type of 802.11 network, whether 802.11b, 802.11a 802.11g, dual-band, etc Sections of the PresentationWhat is Wi-Fi?Brief History of Wi-Fi.Types of Wi-Fi.Why Wi-Fi is used.What is Bluetooth?Brief History of Bluetooth.How does it works.What is its Range.Bluetooth VS Wi-Fi. Objective of this PresentationTo understand what is Wi-Fi and what is Bluetooth.
