Detailed explanation-1: -Approved in December 2012, 802.11ad is very fast-it can provide up to 6.7Gbps of data rate across the 60 GHz frequency, but that comes at a cost of distance – you achieve this only if your client device is situated within 3.3 meters (only 11 feet) of the access point.
Detailed explanation-2: -The maximum range of 802.11a wireless was approximately 95 feet with throughput of up to 54 megabits per second, while 802.11b was capable of transmitting up to 150 feet at 11 Mbps.
Detailed explanation-3: -Also called Wi-Fi, 802.11b operates at 2.4 GHz with a maximum transmission rate of 11M bit/sec. at the access point (AP). Meanwhile, 802.11a operates on the less-crowded 5-GHz band and runs at up to 54M bit/sec.
Detailed explanation-4: -Frequency Ranges of the 802.11 network-types: 802.11n: 2.4GHz & 5GHz bands: 802.11n equipment is made for either 2.4GHz or 5.8 frequency band: 5.8 is typically much less cluttered with signal-traffic. 802.11a: 5GHz band. 802.11b and 802.11g: 2.4GHz only: Operate only in the 2.4GHz frequency band.
Detailed explanation-5: -Wireless 802.11 Definition: 802.11 is a standard that was developed by the Institute of Electrical and Electronic Engineers (IEEE). It is the original wireless specification. Extensions of the 802.11 standard were given the same number with a letter suffix.
