17/06/08: Kyocera Corporation announced that Kyocera’s iBurst-based technology proposal (625k-MC mode) was approved as a new standard for IEEE 802.20 by the IEEE Standards Association at its headquarters, Piscataway, New Jersey, USA on June 12, 2008.
“Having been a draft standard since January 2006, Kyocera is gratified that iBurst has finally been approved as an 802.20 standard by the IEEE Standards Association,” said Mr. Masashi Yano, General Manager of the Corporate Communication System Equipment Division, Kyocera Corporation. “With this industry standard approval, we are expecting to expand the iBurst service area to more and more countries.”
Kyocera’s iBurst, or HC-SDMA, is a mobile broadband wireless access (MBWA) system that has been commercially rolled out in more than 10 countries and has been approved as a standard by American National Standards Institute (ANSI) and International Telecommunication Union Radiocommunication Sector ( ITU-R). iBurst has remarkably high capacity, essential for mobile broadband wireless access services, and distributes its high data rates to many mobile PC users. This is enabled by field-proven Adaptive Array Antenna (AAA) and Spatial Division Multiple Access (SDMA) technologies.
iBurst operators worldwide have formed the iBurst Association (iBA), a not-for-profit organization advocating the promotion and development of iBurst technology as a preferred MBWA solution.
IEEE 802.20 is also known as MobileFi and I have written a blog on it earlier this year.
MobileFi is more of a compitetor to WiMAX as compared to the 3G+ technologies.
WiMAX is targeted for mobile users moving at speeds of up to 60 mph inside a WiMAX region (laptop users moving across a corporate campus, for example). But 802.20 is focused more on highspeed mobile users traveling acrossan extended metropolitan area at speeds of up to 150 mph (a salesman traveling across a city or an executive traveling between nearby cities on a high-speed train, for example). WiMAX/802.16e also differs from 802.20 in that it supports substantially higher data rates (up to 71 Mbps) than 802.20 (up to 1 Mbps). Another thing is that the cell radius with 802.20 is 15km while with WiMAX is 50km.
Why iBurst? The maain Features of iBurst are:
1. High data rate: iBurst supports Data Rate of 1.061Mbps downlink/ 346Kbps uplink with System capacity 24.4Mbps downlink/ 7.9 Mbps uplink.
2. High Spectral Efficiency: iBurst supports more customers per base station. In 5 MHz Spectrum, 50X over-subscription as compared to 3G system
3. Wide Area coverage: Maximum coverage of iBurst is 12.75km. iBurst uses lower frequency, which is good for non-line-ofsight indoor penetration.
4. Mobility: iBurst supports Mobility of over 100km/h. iBurst also supports Handover between base stations.
5. Easy access to IP network: iBurst is packet based technology
6. VoIP compatibility: QoS is implemented to assure wireless VoIP quality. iBurst has achieved fixed phone level voice quality.
