User downlink speeds will double, to 4Mbps, by 4Q 2009;
system will add 700MHz frequency
KYOTO, Japan – April 10, 2008 – Kyocera Corporation (President: Makoto Kawamura)(NYCE:KYO) today announced an enhanced technology for the iBurst® 3.9G Mobile Broadband Wireless Access (MBWA) system that will begin appearing in iBurst base stations and terminals from Kyocera by the 4th Quarter of 2009.
iBurst, a High-Capacity Spatial-Division Multiple Access (HC-SDMA) technology, is a leading solution for mobile broadband wireless communication. With Kyocera’s enhanced technology, the user’s maximum data rate will double, to four megabits per second (4Mbps) in the downlink. Further, iBurst base stations will provide downlinks of up to 32Mbps on a 5MHz band, or 64Mbps at 10MHz, and will support a new frequency of 700MHz.
“We believe the iBurst system represents the world’s most efficient technology for increasing mobile telecommunications throughput on limited bandwidth,” said Mr. Masashi Yano, General Manager, Corporate Communication System Equipment Division, Kyocera Corporation. “With this enhancement, the iBurst system’s spectral efficiency rises to 9.8 bit/sec/Hz per sector in the downlink.”
Employing Spatial Division Multiple Access (SDMA) technology, existing iBurst equipment allows three spatial channels to be used simultaneously to communicate on the same frequency channel and time slot. Using this method, existing iBurst equipment provides user downlinks of up to 2Mbps; base station downlinks of up to 24Mbps; frequencies of 1.8, 1.9 and 2.3GHz; and mobility at speeds exceeding 100km/h (62 mph).*
Kyocera’s new iBurst equipment will deliver higher efficiency and performance through an enhanced SDMAtechnology that supports four spatial channels on the same frequency channel and time slot.
iBurst networks now operate commercially in 11 countries, offering a true mobile broadband solution that is forward-compatible with IEEE802.20, currently in the final stages of standardization. New iBurst networks are now being planned in more than 20 other countries. Kyocera will promote the newly developed 700 MHz capability for deployment in U.S. mobile broadband applications.
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.
