iBurst is a wireless technology developed by ArrayComm. It optimizes the utilisation of its bandwidth with some help from smart antennas. Kyocera is the number one producer of iBurst devices.iBurst is a mobile broadband wireless system that was first developed by ArrayComm and afterwards adopted as the High Capacity Spatial Division Multiple Access (HC-SDMA) radio interface standard, ATIS-0700004-2005, by the coalition of Telecom Industry Solutions ATIS.

The HC-SDMA interface provides wide-area broadband data-connectivity for fixed, portable and mobile computing devices and appliances.The custom is meant to be implemented with smart antenna array strategies to significantly improve the radio frequency RF coverage, capacity and performance for the system. In Jan 2006, the IEEE 802.20 Mobile Broadband Wireless Access Working Group adopted a technology offer that includes the utilisation of the HC-SDMA standard for the 625kHz Multi-Carrier Time Division Duplex TDD style of the future IEEE 802.20 standard.

One Canadian seller which operates at 1.8 GHz. HC-SDMA is also being incorporated by ISO TC204WG16 into its standards to be used in wireless broadband systems in the continuing communications standards design, known as CALM, which ISO is developing for intellectual transport systems ITS. ITS may include applications for public safety, congestion management during traffic situations, automated toll booths, and more. An official liaison has been settled between WTSC and ISO TC204 WG16 for this reason

Technology of HC-SDMA:-

The HC-SDMA interface operates on a corresponding premise as GSM or CDMA2000 for cellular telephones, with hand-offs between HC-SDMA cells continually providing the user with a continued wideband wireless experience even if moving at the velocity of an automobile or train.

The custom:

* mentions base station and customer device RF traits, including output power levels, broadcast frequencies and timing mistake, heartbeat shaping, in-band and out-of band invalid emissions, receiver sensitiveness and selectivity.
* defines associated frame structures for the assorted burst types including standard uplink and downlink traffic, paging and broadcast burst types.
* mentions the modulation, forward boo boo correction, interleaving and scrabbling for numerous burst types.
* describes the various logical channels (broadcast,random access, configuration and traffic channels) and their roles in building communication over the radio link.
* mentions procedures for mistake recovery and retry.
