Competing Wireless Technologies - 802.11 vs. 802.16 vs. 4G mobile telephony IEEE 802.11 commonly known as Wi-Fi is a set of media access control and physical layer specifications for implementing wireless local area network computer communication in various frequency bands such as 2, 3, 3.6, 5 and 60 GHz. 802.16 however is a group of broadband wireless communications standards for metropolitan area networks developed by a working group of the IEEE. On the other hand 4G mobile telephony is the short term for fourth-generation, the stage of broadband mobile communications that will supersede the 3G, known as third generation. A 4G mobile telephony system in addition to usual voice and other services of 3G provides mobile broadband…show more content…
Wi-Fi even has problems with interference, and output and that is why voice, data, and video technologies cannot be hosted on traditional Wi-Fi. In contrast, 802.16 use a scheduling algorithm. This algorithm allows the user to only compete once for the access point. This gives 802.16 advantages for example in output, latency, spectral efficiency, and advanced antenna support. 802.11 is essentially an implementation of WLAN within a short range like a college for example whereas 802.16 on the other hand is a metropolitan technology whose objective is to interconnect houses for example to allow communication between them and with other networks. Though recently 802.16 technologies has several advantages compared to 802.11. They have a better reflection tolerance; a better penetration of obstacles; and an increased in the number of interconnections. Though 802.16 standard goals aren’t to replace 802.11 in its applications, but want to supplement it in order to form a wireless network web. Despite the similarity in equipment cost, 802.16 technologies require a costly setup in contrast to 802.11 which can easily be installed using low cost access points. Therefore having 802.11 and 802.16 wireless technologies, they both have common components in their operations however with a difference in communication range. Since mobile technology has advanced since the early 2000’s, mobile devices can be enabled to use a variety of
