IBurst

iBurst is a wireless broadband technology originally developed by ArrayComm
. It optimizes the use of its bandwidth with the help of smart antennas. Kyocera
is the manufacturer of iBurst devices.
in April 2000.
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.
HC-SDMA was announced as considered by 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.
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.
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 625kHz Multi-Carrier time division duplex (TDD) mode of the standard. One Canadian vendor operates at 1.8 GHz.
The HC-SDMA interface operates on a similar premise as cellular phones, with hand-offs between HC-SDMA cells repeatedly providing the user with a seamless wireless Internet access
even when moving at the speed of a car or train.
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.
Currently deployed iBurst systems allow connectivity up to 2 Mbit/s for each subscriber equipment. Apparently there will be future firmware upgrade possibilities to increase these speeds up to 5 Mbit/s, consistent with HC-SDMA protocol.
