doctors. When a medical emergency happens, the social network can help call the 911 centre, drive an
ambulance, assist patients, advice doctors, and notify the hospital simultaneously.

Strategic trends for deployment of future ICT infrastructure
In order to deploy future ICT infrastructure successfully, there are three strategic issues as shown in Figure
12. First, the well-organized wireline/wireless network will be a good basis to construct the future ICT
infrastructure. From traffic demands and application types, user equipment and sensor devices will be plug-
in the network mostly by using 5G or WiFi wireless technologies. At the edge and core network, optical
systems with more than 100 Gigabits/s per wavelength will be available in the near future. The passive optical
network system of more than 10 Gigabits/s will replace the existing copper cable and unshielded twisted
pairs at the access network. Second, from the viewpoint of information sharing platform, all the data created
by users and collected by machines are efficiently and effectively stored at certain servers. From this
platform, the public information for human life and business may be easily accessed within a few seconds.
Moreover, some of the government-owned information may be freely and easily obtained. The design
guideline of the information sharing platform is how to access data with acceptable scalability and
confidentiality. The cloud computing platform will be a good candidate to be a future information sharing
platform.

Third, from the viewpoint of knowledge creation, the most outstanding issues are how to support a creative
knowledge eco-society with innovative ideas. Here, it is noted that all the relevant information and
knowledge are created, shared, processed, and utilized originally by human beings. If some people raise
questions, interests, and/or curiosity, they can share the relevant information and knowledge easily at that
instance. However, unfortunately, the current cloud computing system is mainly designed only for efficiency
of storage and processing. This means that the cloud computing platform will be evolved to help people's
curiosity. In addition, the digital data format which is used to display video screening and deliver
audio/sound/voice signals should be evolutionally tuned with the human organ and human perception
mechanism. Until now, the data structure and formats are defined and classified according to the spectrum
of long-lived knowledge silo as in education, transportation, energy, health, science, and engineering, etc.
New integrated data formats based on semantic ontology may be challenging, which are easily interpreted
and perceived by users.
