Overview NTT Communications is taking up the challenge of creating new business under its Vision 2015 growth strategy. What kind of approach is needed to achieve true globalization in an ICT market that demands quick results? We asked President & CEO Akira Arima to tell us about current trends in the ICT market and the strategy of leveraging the strengths of a telecom carrier in the field of cloud services.
Feature Articles: NTT I3—Seeking to Actively Develop Global Cloud Services
Abstract NTT”Ēs Medium-Term Management Policy Towards the Next Stage calls for the early development and marketing of world-class cloud and security technologies in North America, the most competitive market in the world. To achieve this objective, NTT Innovation Institute, Inc. (NTT I3) was established on April 1, 2013 as a research and development center in North America. This article introduces the NTT Group”Ēs global business strategy and the role of NTT I3 in executing this strategy.
Abstract NTT Innovation Institute, Inc. (NTT I3) has been analyzing security intelligence in collaboration with the NTT Computer Security Incident Response and Readiness Coordination Team, also known as NTT-CERT, and other CSIRTs, or Computer Security Incident Response Teams, and it aims to apply this know-how to the research and development of advanced security technologies. We asked Shin Adachi, the Lead Security Analyst at the center of security-related work at NTT I3, about the current status of information security and the benefits of establishing NTT I3 as a center for research and development in North America.
Abstract NTT I3 (NTT Innovation Institute, Inc.) has actively been carrying out the tasks of developing cloud-related network technologies. Software-defined networking (SDN) in particular is considered to be a key technology for creating differentiation services for service providers such as NTT. Robert Raszuk, Distinguished Research Engineer at NTT I3, has a lot of experience in achieving company visions of implementing networking and SDN. We asked him about the current status and prospects of SDN.
Abstract The newly developed magnetic resonance wireless power transfer technology is being intensively researched since it is easier to use than conventional technology and has potential applications in various fields. In this article, we first provide an overview of similar techniques; then we introduce a method of this power transfer technology that adopts load modulation in order to increase its range of applicability. We also describe an example of how this method can be used to reduce the effort needed for manhole maintenance, and we present evaluation results regarding the optimal placement of the transmitter and receiver coils in the example application.
Abstract This article presents the results of an electric-power-reduction experiment that was conducted in collaboration with the NTT WEST Kochi branch. One effective way to reduce the amount of electric power required for air conditioning in a telecom equipment room (TER) is to eliminate hot spots. In the experiment, the causes of two hot spots generated in the existing TER were analyzed, and various heat-control methods were implemented to eliminate them. Then the effects these methods had on reducing the temperature and on reducing the required air conditioning power were evaluated.
Abstract This article gives an overview of the Institute of Electrical and Electronics Engineers (IEEE) 802.11 Working Group (WG), which creates standards for wireless local area networks (LANs). We include information on its relationships with external organizations, its standardization processes, and a list of existing amendments to IEEE 802.11. Some of the latest trends in standardization are also introduced, including IEEE 802.11ac, which is an amendment of the IEEE 802.11 standard to increase system throughput, and we explain the status of the High Efficiency WLAN Study Group (HEW SG), which has begun standardization work to enhance transmission efficiency in high-density deployment of access points and stations.
Practical Field Information about Telecommunication Technologies
Abstract In this article, we explain some case studies of recent IP (Internet protocol) problems that have occurred in homes. This is the nineteenth in a bimonthly series on the theme of practical field information on telecommunication technologies. This month”Ēs contribution is from the Network Interface Engineering Group, Technical Assistance and Support Center, Maintenance and Service Operations Department, Network Business Headquarters, NTT EAST.
