Does your cellphone drop off the radar in most basement locales? Help may be on the way. A new “repeater” device that enables cellphones to receive signals underground has been jointly developed by the four major mobile phone companies: NTT DoCoMo Inc., KDDI Corp., Vodafone KK and Tu-Ka Cellular Tokyo Inc.
KDDI will introduce EV-DO Rev.A that enhances the function of the CDMA2000 1x EV-DO method, which is the infrastructure for their data communication on au cellphones, by the end of 2006. It is assumed that with the construction of an “Ultra 3G” network, the fixed movement integrated communication infrastructure will enable improved connection speed of up to 3.1Mbps service. The decision for this next generation standard was made at a recent 3GPP2 meeting in the United States by joint proposal of 29 major telecomm equipment manufacturer companies worldwide.
Lucent Technologies and eAccess Ltd., today announced that the two companies have completed successful High-Speed Downlink Packet Access data calls as part of a third- generation (3G) Wideband-CDMA (W-CDMA) network trial announced earlier this year. The testing took place in May and used the 1.7 Gigahertz (GHz) spectrum band that is being made available in Japan for the deployment of mobile service. Following these successful tests, the two companies plan to conduct a field trial in commercial and residential areas of Tokyo in the coming months. The trial will include deployment of an HSDPA-enhanced W-CDMA network in the 1.7 GHz spectrum band, and also will incorporate Lucent’s IP Multimedia Subsystem (IMS) solution.
Vodafone KK , Japan’s third-largest mobile operator, will boost its capital investment by 50 percent to 260 billion yen ($2.43 billion) this business year to accelerate installation of base stations for 3G services, the Nihon Keizai business daily said on Tuesday.
Corrigent Systems, a leading provider of Packet ADM (Add Drop Multiplexer) for next-generation transport networks, today announced that its CM-100 Packet ADM was selected by KDDI for the second phase deployment of its nationwide buildout of packet-based metro transport network in Japan. KDDI will use the 10Gbps Corrigent Packet ADM for its second phase build that consists of expanding its service areas further. The first phase deployment, announced last year and consists of over 1,000 units of the CM-100 packet ADM, is carrying commercial traffic. KDDI’s packet-based metro networks are built to support new services such as Metal-Plus for IP-based telephony and Hikari-Plus, a complete voice, video and data triple-play offering, as well as KDDI’s 3G cellular telephony services.
Though Softbank seems to be making more headlines with their pro baseball team, the Hawks, than Internet and broadband ventures, the company is moving decidedly forward in its long-range plan to provide mobile W-CDMA phone service in the domestic market. On 30 May, the company received its hard-fought for license to test service in the 1.7-gigahertz band. This is not yet a license for full operation as the Ministry of Internal Affairs and Communications is still working on allocation policy for this and one other bandwidth.
