Telecommunication Systems for Realizing a Smart City
In order to realize a smart city, it is important to use IT to connect a variety of everyday living services to public infrastructures, such as electric power, railways, and water. To this end, a communication network is necessary to establish all sorts of connections, including human to human, human to machine, machine to machine. A communication network that can connect all sorts of things is required that can achieve a convenient and comfortable lifestyle for people, while at the same time giving consideration to ways of reducing the system’s impact on the natural environment.
Telecommunication Systems Connecting Everything
As part of the realization of a smart city, communication systems are an indispensable part of the public infrastructure. The reason for this is that many of the requirements of a smart city, including creating systems to reduce the environmental load, revitalization of corporate activities, and the achievement of comfortable living can only be realized by seamlessly coordinating everything.
For instance, when cloud services, videoconferencing, and other such services that utilize high-speed and high-capacity communication networks spread, this allows corporations and local governments to move forward not only in the increase of work efficiency and the improvement of convenience, but in the creation of new value as well. In the home as well, in addition to the connection of telephones and PCs to the Internet, by connecting all other types of devices including home appliance products and automobiles to the network, it becomes possible to expand a lifestyle that is more enjoyable, more secure, and more convenient. Also, with all citywide services connected to the network, including transportation, distribution, finance, energy, and so on, all of these services are able to coordinate closely, which in turn makes it possible to provide services that are even more secure and convenient while simultaneously giving consideration to the global environment.

A Network Usable While Living Unaware of Its Existence
A smart city is one where a variety of different services is available without the need to be aware of the network. When there is always a dependably secure network nearby, this will lead to even further increases in new terminals and communication services that are secure and safe, and even more enjoyable and convenient.
Examples include the ability to start watching a TV show at home, and then continue watching it on a smart phone in a train, or to check up on children at home from outside via a mobile phone, or to buy freshly baked bread together with people who just happen to be in the same area, sharing an order. Users of these kinds of services do not need to be aware of the information that are occurring, and can still comfortably enjoy the services.
In a smart city, everything is “connected” to the network, which also revitalizes businesses.
The benefits of cloud services are maximized through the use of a high-speed, high-reliability network, and this will enable the expansion of operations, the creation of new business opportunities, and more rapid responses to changing markets. In addition, the communication system of a smart city will also be connected to the world’s communication network, thereby revitalizing global business as well. Videoconferencing and other visual communication services will also continue to improve in both image and sound quality.
Furthermore, when various types of sensing technology coordinate, the operation and management of systems also stabilize. Even when the operator is far away, this coordination makes it possible to rapidly and precisely respond to the signs of trouble before it occurs, thereby holding damage to a minimum if something should happen.
Networks that Reduce the Load on the Environment
Since everything is connected to the network, there is the concern that the various data transactions that occur might increase the consumption of electric power by the network.
It is first necessary to hold power consumption to the bare minimum starting from the design stage. By giving consideration to energy consumption and pursuing efficiency as a whole system starting with the design stage, it becomes possible to reduce the environmental load by increasing traffic.
Also, it is necessary to optimize energy consumption by utilizing the network itself. By grasping the energy usage state in real time over the network, it is possible to analyze how energy is used, not only improving user awareness of energy consumption, but achieving optimal usage while enjoying the network at the same time. Taking the area of mobility as an example, if automobiles communicate with each other or with a road system, it can optimize the flow of automobiles, thereby achieving comfortable and safe driving without congestion while reducing energy consumption in the mobility sector at the same time.
This is how a smart city allows reducing the load on the global environment without the need to sacrifice comfortable living, through the seamless coordination of every component.
