iBurst (or HC-SDMA, High Capacity Spatial Division Multiple Access) is a wireless broadband technology originally developed by ArrayComm. It optimizes the use of its bandwidth with the advice of acute antennas. Kyocera is the architect of iBurst devices.

Description
iBurst is a adaptable broadband wireless admission arrangement that was aboriginal developed by ArrayComm, and appear with accomplice Sony in April 2000.1 It was adopted as the High Accommodation – Spatial Analysis Multiple Admission (HC-SDMA) radio interface accustomed (ATIS-0700004-2005) by the Alliance for Telecommunications Industry Solutions (ATIS). The accustomed was able by ATIS’ Wireless Technology and Systems Committee’s Wireless Wideband Internet Admission subcommittee and accustomed as an American National Accustomed in 2005.2
HC-SDMA was appear as advised by ISO TC204 WG16 for the connected communications standards architecture, accepted as Communications, Air-interface, Long and Medium ambit (CALM), which ISO is developing for able carriage systems (ITS). ITS may cover applications for accessible safety, arrangement bottleneck administration during cartage incidents, automated assessment booths, and more. An official communication was accustomed amid WTSC and ISO TC204 WG16 for this in 2005.2
The HC-SDMA interface provides wide-area broadband wireless data-connectivity for fixed, carriageable and adaptable accretion accessories and appliances. The agreement is advised to be implemented with acute antenna arrangement techniques (called MIMO for multiple-input multiple-output) to essentially advance the radio abundance (RF) coverage, accommodation and achievement for the system.3 In January 2006, the IEEE 802.20 Adaptable Broadband Wireless Admission Working Group adopted a technology angle that included the use of the HC-SDMA accustomed for the 625kHz Multi-Carrier time analysis bifold (TDD) approach of the standard. One Canadian bell-ringer operates at 1.8 GHz.

Technology
The HC-SDMA interface operates on a agnate apriorism as cellular phones, with hand-offs amid HC-SDMA beef again accouterment the user with a seamless wireless Internet admission even if affective at the acceleration of a car or train.
The protocol:
specifies abject abject and applicant accessory RF characteristics, including achievement ability levels, address frequencies and timing error, beating shaping, in-band and out-of bandage affected emissions, receiver acuteness and selectivity;
defines associated anatomy structures for the assorted admission types including accepted uplink and downlink traffic, paging and advertisement admission types;
specifies the modulation, advanced absurdity correction, interleaving and scrambling for assorted admission types;
describes the assorted analytic channels (broadcast, paging, accidental access, agreement and cartage channels) and their roles in establishing advice over the radio link; and
specifies procedures for absurdity accretion and retry.
The agreement aswell supports Layer 3 (L3) mechanisms for creating and authoritative analytic access (sessions) amid applicant accessory and abject including registration, beck start, ability control, handover, hotlink adaptation, and beck closure, as able-bodied as L3 mechanisms for applicant accessory affidavit and defended manual on the abstracts links. Currently deployed iBurst systems acquiesce connectivity up to 2 Mbit/s for anniversary subscriber equipment. Apparently there will be approaching firmware advancement possibilities to access these speeds up to 5 Mbit/s, constant with HC-SDMA protocol.citation needed

Commercial use
Various options are already commercially accessible using:
Desktop modem with USB and Ethernet ports (with alien ability supply)
Portable USB modem (using USB ability supply)
Laptop modem (PC card)
Wireless Residential Gateway
Mobile Broadband Router
iBurst was commercially accessible in twelve countries in 2011 including Azerbaijan,4 Norway, Ireland, Canada, Lebanon,5 and USA.6 iBurst (Pty) Ltd started operation in South Africa in 2005.7 iBurst Africa International provided the account in Ghana in 2007, and again after in Mozambique, Democratic Republic of the Congo and Kenya.8 MoBif Wireless Broadband Sdn Bhd, started account in Malaysia in 2007, alteration its name to iZZinet.9 The provider accomplished operations in March 2011.citation needed T3 Wireless, a accessory of Pacific Internet, offered iBurst in Australia. BigAir acquired the barter in 2006,10 and shut down iBurst account in 2009.11
