We have experienced that when a large-scale disaster arises, the existing network-communication system in the disaster area becomes downed by damage of network communication facilities , stop of an electric power supply and increase of traffic through some large-scale disasters. When a large-scale disaster arises, it is important that a disaster victim secures information-sharing means in the disaster area for lifesaving, escaping, guidance, and person finding which can be used immediately after the disaster arises. In this symposium, we discuss the information-sharing system
for lifesaving, escaping, guidance and person finding which can be used by disaster victims in the disaster area immediately after the disaster arises.

Considering natural large scale disasters (earthquake, heavy rain, tornado and so on), traffic accidents or crimes for children, information and communication systems are very useful for defense or mitigation of the damage, moreover, retrieve or reconstruction of the disaster-stricken area.

In addition, the usage on the higher frequency band and small cells for the broadband transmission.
On the other hand, heterogeneous networks, which overlay picocell and femtocells onto marcocell, is proposed for improving the system channel capacity. In this symposium, we invite the session which deals with latest technologies on antenna, propagation, and systems: technologies on broadband transmission, small cell, and frequency sharing, and so on which are essential for future wireless systems. We also discuss the research and development and future prospect on this topic.

We have been studing on wireless networks with a lot of small cell base stations, which are expected to have a large frequency bandwidth and are densely deployed. The motivation of such a small cell deployment is to deal with sharply increasing mobile traffic in wireless networks. In accordance with the trend of deploying a lot of small cell base stations, it is anticipated that a various kinds of cooperations and coordinations such as among base stations, between base and mobile stations, between base stations and core networks will be required. This symposium session calls for papers on various kinds of cooperation and coordination technologies and techniques for wireless networks with a large number of small cells. The objective of the session is to concentratively discuss the technologies and techniques.

Many research projects and experiments are going on to realize xEMS
(HEMS, BEMS, FEMS, etc.) which makes efficient utilization of energy in many segments of society such as home, building and factory possible. For xEMS, wide variety of technologies such as network technology for data acquisition and control, gateway technology to connect each site (home, building, factory, etc.) to cloud and data management and processing technology in cloud are needed.
In this symposium, we will have presentations and make discussions on
the latest technologies of network and system to realize xEMS.

This session handles the themes on Network Technology.The presentation style is poster session so that people in the room including speakers could hold an active and fruitful discussion anytime during the session and could have feedbacks or tips for his or her own study. As the session aims to have a discussion about research topics in progress, 1 written paper would be sufficient.

Attentions have gathered for the energy technology which constitutes a smart grid. In the field of energy technology, energy saving and energy generation were formerly main themes.
