INTRODUCTIONWireless communication can be simply defined as a type of data communication that isbeing performed and transferred wirelessly (Arnon, Barry and Karagiannidis, 2012). This is awide term that consists of every procedure and form of connecting and communicating amongtwo or more devices that are using a wireless signal via technologies and instruments of wirelesscommunication. The present report is based on wireless communication whereby differentstandards of WiMAX networks are compared and contrasted. It also describes the securitychallenges of WPAN technologies.TASKS1. Comparison of three encryption standards of WiMAX networks802.11802.16802.16aThis standard describes ordefines the wireless LAN(Local Area Network)technology based products. But it defines WiMAXtechnology based products.It also defines WiMAXtechnology based products. The standard variants are802.11a, 11b, 11g, 11n, 11ac,11ad, etc. While its standard variants are802.16a, 302.16d, 802.16e,802.16m, etc. This is a standard variant of802.16. The coverage range is from 30to 100 metres.While its coverage range isfrom 7 km to 50 kmIt covers more large range incomparison to 802.16. It is used in indoor.While it is in outdoorIt is also used in outdoor.The band width of thisstandard is 20MHz, 80MHz,40MHz and 160MHzaccording to the standardvariants.On the contrary, in this casedynamic allocation is done asper the need from 1.5 to 28MHzWhile the band width of this standard variant is selectable that is from 1.25 to 20 MHzData rate is up to 54Mbps inlegacy WLAN (11a), 300 to600Mbps (11n), Gbps in802.11ac/11ad.Whereas the data rate of thisstandard is 150 Mbps as perBW of use.On the other hand, data rate this variant is less than 70 or 100 Mbps, (20 MHz BW channel).1
