Recent Advances in Distributed Antenna Network for Gigabit Communications
Abstract: Wireless networks must be restructured to cope with recent rapid popularity of smart phones. In the near future, everyone will be always connected to the network and will enjoy a variety of cloud computing data services (throughput per user ranges from a few kbps to close-to-giga bps) including voice/video conversation. Gigabit data services need prohibitively high transmit power and broad bandwidth if the present network architecture is employed. The available frequency bandwidth and power are too limited to provide gigabit data services to everyone. A new wireless network architecture that can efficiently utilize the limited bandwidth and significantly reduce the transmit power is required. One promising architecture is the distributed antenna network (DAN). In this talk, we will overview the concept of DAN and recent advances in dynamic frequency reusing, massive MIMO, multiple access, frequency-domain signal processing, etc., which are important elements in realizing DAN.

ICT for the Resilient Society
Abstract: For more than 10 years, I have been working towards the realization of the “Human Centric ICT System”, which is now becoming the reality. On March 11th, 2011, Japan was attacked sever disaster named Eastern Japan earthquake and Tsunami, and about 20,000 people lost their lives. ICT system was also damaged, and made it difficult to carry out quick restoration and recovery process. This strongly reminded ICT engineers that the ICT system is the life line of the society, and many discussions started about “How the ICT system should be”. I have been deeply involved to one of the committee activities whose theme is to realize an ICT system to contribute creating a safe and secure resilient society. The direction of the system paradigm is in good match with the Human Centric ICT System. In my talk, I will introduce the major outcomes of the committee activities together with the concept of the Human Centric ICT System.

Queuing Models for the Internet
Abstract: The analysis of modern networks, especially 3G and 4G mobile networks supporting multi-service traffic, requires the development of relevant analytical models of network-based systems. One of the more important problems currently faced by engineers is the need for designing simple and efficient queueing models for multi-service traffic. So far, no satisfactory solutions were invented, such that would allow the assessment of queue parameters for various classes of calls with diverse QoS parameters. Only approximate results were obtained for borderline cases. In traffic theory, the problem is formulated as the “Erlang formula for the Internet”, and it is considered by scientific and engineering circles.
In the presentation, the author will describe the results of recent works on ulti-service queuing systems. An approximate approach based on the single-service Erlang model will be discussed, along with proposals of precise models with a variable bitrate of a multi-service server. In such models, the quantity of the resources handled in a given state of occupancy depends on the division of this state between different classes of calls, i.e., on the number of calls of individual classes in a given occupancy state. Therefore, the bitrate assigned by a server to a selected class of calls changes along with the system change.
