== Description ==
iBurst is a mobile broadband wireless access system that was first developed by ArrayComm, and announced with partner [[Sony]] in April 2000.<ref>{{cite news |title= The Wireless Advantage |author= Geneva Sapp |date= May 1, 2000 |work= Computerworld |url= http://www.computerworld.com.au/article/88158/wireless_advantage/ |access-date= August 21, 2011 }}</ref>
It was adopted as the High Capacity – Spatial Division Multiple Access (HC-SDMA) radio interface standard (ATIS-0700004-2005) by the [[Alliance for Telecommunications Industry Solutions]] (ATIS).
The standard was prepared by ATIS’ Wireless Technology and Systems Committee's Wireless Wideband Internet Access subcommittee and accepted as an American National Standard in 2005.<ref name="atis">{{cite news |title= ATIS Standard Enables Seamless Wireless Wideband Connectivity at High Speeds |work= News release |publisher= ATIS |date= September 26, 2005 |url= http://www.atis.org/PRESS/pressreleases2005/092605.htm |access-date= August 21, 2011 |archive-date= March 15, 2012 |archive-url= https://web.archive.org/web/20120315152130/http://www.atis.org/PRESS/pressreleases2005/092605.htm |url-status= dead }}</ref>

HC-SDMA was announced as considered by [[International Organization for Standardization|ISO]] TC204 WG16 for the continuous communications standards architecture, known as [[Communications, Air-interface, Long and Medium range]] (CALM), which ISO is developing for [[intelligent transport systems]] (ITS). ITS may include applications for [[public safety]], [[network congestion]] management during traffic incidents, automatic toll booths, and more. An official liaison was established between WTSC and ISO TC204 WG16 for this in 2005.<ref name="atis"/>

The HC-SDMA interface provides wide-area broadband wireless data-connectivity for fixed, portable and mobile computing devices and appliances. The protocol is designed to be implemented with [[smart antenna]] array techniques (called [[MIMO]] for multiple-input multiple-output) to substantially improve the [[radio frequency]] (RF) coverage, capacity and performance for the system.<ref>{{cite web|title=Mobile Broadband - A Third Generation - but not as we know it |date=June 30, 2005 |author=David Brunnen |publisher=Groupe Itellex |url=http://www.groupe-intellex.com/japan5.htm |url-status=dead |archive-url=https://web.archive.org/web/20051027123432/http://www.groupe-intellex.com/japan5.htm |archive-date=October 27, 2005 }}</ref>
In January 2006, the IEEE 802.20 Mobile Broadband Wireless Access Working Group adopted a technology proposal that included the use of the HC-SDMA standard for the 625[[kHz]] Multi-Carrier [[time-division duplex]] (TDD) mode of the standard. One Canadian vendor operates at 1.8&nbsp;GHz.
