Write-up upon Wimax, LTE and 3.5G
WiMAX is an IP dependent, wi-fi broadband arrive at technological innovation that gives functionality very similar toward 802.11/Wi-Fi networks with the insurance and QOS of mobile networks. WiMAX is way too an acronym indicating 揥orldwide Interoperability for Microwave Attain (WiMAX). The significant differnce amongst a WIMAX and cell GPRS is inside rate, wherever WIMAX specials significant bandwidths.
WiMAX could commonly be separated inside in direction of 2 classes:
i. Non-line-of-sight: Below a lower antenna at the purchaser premises communicates with the foundation antenna located at the WiMAX tower. Within just this manner, WiMAX works by using a minimal frequency number ?2 GHz towards 11 GHz (equivalent towards Wi-Fi).
ii. Line-of-sight: Listed here, a treated dish antenna info at buyer premises details instantly in direction of the WiMAX tower towards a rooftop or pole. The line-of-sight romance is dependable and excess sound, thus it抯 equipped in the direction of shift excess details with a lot less faults. Line-of-sight transmissions seek the services king of thieves hack tool of superior frequencies, with levels acquiring a up in direction of 66 Ghz.
WiMAX know-how is primarily based upon IEEE 802.16 . A few types of the IEEE 802.16 criteria are presented beneath:
1. IEEE 802.16-2004 (or 802.16d): Based mostly upon Orthogonal Frequency Department Multiplexing (OFDM), and supports cured and nomadic reach.
2. IEEE 802.16e-2005 (or 802.16e). Dependent upon Orthogonal Frequency Section A number of Arrive at (OFDMA), this common model supports remedied and nomadic attain, nevertheless it on top of that incorporates even more functions towards provide cellular attain.
3. IEEE 802.16m: At present below growth, the fresh new edition of the common will contain far better cell get to and voice products and services and is a applicant for inclusion as a person of the upcoming ITU IMT-Highly developed technological innovation.
The sensible elements of a WiMAX community consist of Foundation stations, Attain serice community, and Cell stations.
The traditional plans supported via WiMAC incorporate the right after:
1. Broadband Net achieve
2. Movie streaming
3. Legitimate season packages
4. VoIP, Online video upon Require
5. Telemedicine software package/Online video Meeting, and other people.
