This wireless broadband technology is also known and promoted as iBurst (or HC-SDMA, High Capacity Spatial Division Multiple Access).

iBurst is a mobile broadband wireless access system that was first developed by ArrayComm, and announced with partner Sony in April 2000.

[2] 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).

ITS may include applications for public safety, network congestion management during traffic incidents, automatic toll booths, and more.

[3] 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.

The standard's proposed benefits: Some technical details were: The protocol: The protocol also supports Layer 3 (L3) mechanisms for creating and controlling logical connections (sessions) between client device and base including registration, stream start, power control, handover, link adaptation, and stream closure, as well as L3 mechanisms for client device authentication and secure transmission on the data links.

[citation needed] The 802.20 working group was proposed in response to products using technology originally developed by ArrayComm marketed under the iBurst brand name.

[5][3] The Mobile Broadband Wireless Access (MBWA) Working Group was approved by IEEE Standards Board on December 11, 2002, to prepare a formal specification for a packet-based air interface designed for Internet Protocol-based services.

[8] The unprecedented step came after other working groups had also been subject to related allegations of large companies undermining the standard process.
