Channel bandwidth 28G 400MHz bandwidth 4.5G 100MHz bandwidth 3.7G 100MHz bandwidth 3.5GHz 5G uses frequency bands that can secure 3.4GHz a wider channel bandwidth compared to the 2GHz frequency bands assigned for 4G, which enables 1.7GHz faster speeds and larger capacity! 1.5GHz 800MHz New frequency bands 700MHz 4G bands Copyright ©2020 NTT DOCOMO, INC. -
The Year of Globalisation for Cdmaone™ by Perry Laforge, Executive Director, COMA Development Group, USA
The Year of Globalisation for cdmaOne™ by Perry LaForge, Executive Director, COMA Development Group, USA Abstract The adoption rate, of cdmaOne™ has been the fastest of any wireless technology to date. It is already used in more than 30 countries around the world, serving over 7.8 million customers on five continents. The prediction is that by the year 2000 there will be about 60 million Wireless Local Loop (WLL) subscribers around the world, which represents 15% of the global mobile market, and growing to 200 million subscribers by 2005. Here, Mr. Perry LaForge of the COMA Development Group explains why he believes 1998 is the year of globalisation for the technology. The adoption rate of cdmaOne has been the fastest of any technology to date, and its adoption by major high growth wireless markets around the globe will continue to fuel subscriber growth and improve worldwide economies of scale. CDMA in Europe The unique, inherent advantages of cdmaOne, such as superior voice quality, longer battery life, and unexcelled call capacity have prompted enthusiasm for the technology even in Europe, where competing standards have historically dominated the marketplace. Nowhere is this demonstrated more clearly than the preliminary results of a field trial conducted in the UK by Vodafone Ltd. and QUALCOMM, Inc. The trial successfully displayed the technical feasibility of cdmaOne-Global System for Mobile Communications (GSM) integration, while maintaining cdmaOne over-the-air performance. Elsewhere in Europe, cdmaOne fixed wireless networks are being adopted in Poland, Ukraine and Russia. Customer Satisfaction In North America, where the competition from other digital technologies is most intense, cdmaOne has emerged as the dominant wireless standard. -

Zenji Nakazawa
TELECOMMUNICATIONS, ENVIRONMENT/ENERGY AND HEALTH 83 Telecommunications, Environment/Energy and Health Zenji Nakazawa n 1997 monumental sea changes were rocking the world of telecommunica- tions in both the U.S. and Japan. President Bill Clinton had just signed the ITelecommunications Act of 1996. This legislation, which was the single largest revision of U.S. telecommunications law in more than sixty years, focused on promot- ing local competition by eliminating barriers to entry for new telecommunications service providers. And in Japan, the drumbeat for market liberalization was grow- ing louder as the government of Japan proposed restructuring the nation’s flagship telephone carrier, Nippon Telegraph and Telephone (NTT). These twin waves of change formally converged with the consummation of the World Trade Organization’s Agreement on Basic Telecommunications Services in 1997—the same year I began my journey as a member of the third class of Mansfield Fellows. My first Fellowship placement was with the Ministry of Posts and Telecommunications (MPT), which is now the Ministry of Internal Affairs and Communications, the Japanese regulatory equivalent to the Federal Communications Commission (FCC). My work at MPT provided me with an invaluable insider’s view of the ministry’s decision-making process just at a time when it was embarking on a set of new policy initiatives to promote market-based competition. As part of my “education” at MPT I was asked to join a study group, which was work- ing on an overhaul of the laws and regulatory policies governing interconnection rates. These are charges one telecommunications provider who does not have its own facilities, such as a switch, must pay to interconnect to the network facilities owned by a second provider in order to complete a call. -
