Motorola has won a wide-ranging contract to build a cellular network in Japan. The leading edge network will be used by two of the country's cellular service providers, DDI and IDO, which will invest a total of $3 billion in the project.
The network will be based on code division multiple access (CDMA) technology. It will initially be available in six cities in Japan and across the country by 1999. One million extra people subscribe to Japan?s cellular network every month - at the end of February this year, 20 million people were subscribers.
CDMA is considered as the next generation of cellular network technology after GSM, which is mainly used in Europe. CDMA was first introduced into the market in Hong Kong in 1995 and Motorola has built CDMA networks in Peru, with another one planned in Singapore. The project in Japan will represent the largest CDMA network in the Asia-Pacific region.
DDI will open the network in the Kansai area, which includes the cities of Osaka, Kobe and Kyoto. The IDO portion of the network will cover the Kanto and Tokai areas of Tokyo, Nagoya and Nagano. By 1999 CDMA will cover more than 1,500 cell sites.
