ARLINGTON HEIGHTS, Ill.-Motorola Inc.’s Cellular Infrastructure Group announced two of Japan’s leading cellular service providers have selected it to deploy a trial of a third-generation wideband cdmaOne system.
DDI and IDO said the trial system, based on Code Division Multiple Access Interim Standard-95 technology, will be based in Japan’s Kanto region. DDI and IDO will operate under an experimental license in the 2 GHz frequency band, which is part of the proposed IMT-2000 frequency band reserved for worldwide wireless use. Construction is set to begin immediately.
The goal of the system trial is to evaluate, research and develop the cdma2000 wireless transmission method that has follow-on compatibility with cdmaOne, the method on which DDI and IDO are working together to achieve seamless, countrywide service, said Motorola.
Motorola last year was awarded a contract by DDI and IDO to deploy a nationwide cdmaOne network. DDI is expected to offer commercial cdmaOne service in Kansai in July. IDO is scheduled to launch cdmaOne service in Tokyo next spring.
NTT DoCoMo, Japan’s largest cellular operator, is in the midst of constructing a W-CDMA 3G network in conjunction with L.M. Ericsson, Nokia Corp. and Lucent Technologies Inc. The technology is based on Global System for Mobile communications technology.
