Executive Summary
Our project is to co-develop a new and flexible wireless network in order to narrow digital divide area and improve energy consumption. We can design its function through evaluation of a new system by reflection of discussion, investigation etc. The term “new” means that this system function consists of not only public telecommunication network for general user but also private network of power utilities for the deployment of Smart Grid which will be the trend of power grid in the future. The term “flexible” means that there is no restriction of installation place of terminal equipment by introducing high speed wireless system as transmission line. Therefore, both of fixed terminal equipment and mobile terminal equipment can be applied easily.
In addition to the fundamental functions of narrowing digital divide area such as providing broadband access to general user in rural area, and realizing Smart Grid concept, the EMS (Energy Management System) service system for help/support of customer’s energy saving action and Disaster Information System for public safety can be added very easily. Our new and flexible system can have many users such as telecommunication companies which supply IT service to general user in rural area, power utilities which plan to realize Smart Grid concept, disaster management organizations which can gather disaster information from network camera and broadcast disaster information in order to alert people. This means that the return of system investment can be easier than conventional systems which help narrowing digital divide area.
In this project, we co-develop above excellent system and design this system through the result of mutual discussion and understanding between both countries.

1. Project Information
1.1 Introduction Our project is to co-develop a new and flexible wireless network in order to narrow Digital Divide
area and improve energy consumption. We can design its function through evaluation of a new system by reflection of discussion, investigation, etc. The term “new” means that this system function consists of not only public telecommunication network for general user but also private network of power utilities for the deployment of Smart Grid which will be the trend of power grid in the future. The term “flexible” means that there is no restriction of installation place of terminal equipment by introducing high speed wireless system as transmission line. Therefore, both of fixed terminal equipment and mobile terminal equipment can be applied easily.
In addition to the fundamental functions of narrowing Digital Divide area such as providing broadband access to general user in rural area, and realizing Smart Grid concept, the EMS (Energy Management System) service system for help/support of customer’s energy saving action and Disaster Information System for public safety can be added very easily. Our new and flexible system can have many users such as telecommunication companies which supply IT service to general user in rural area, power utilities which plan to realize Smart Grid concept, disaster management organizations which can gather disaster information from network camera and broadcast disaster information in order to alert people. This means that the return of system investment can be easier than conventional systems which help narrowing Digital Divide area.
In this project, we co-develop above excellent system and design this system through the result of mutual discussion and understanding between both countries.

3.1 Final System In order to narrow Digital Divide area, new telecommunication investment is inevitable but it is not
worth to invest such big system in rural area because the density of customers in rural area, where broadband service is restricted, is very low. Therefore, we propose a new and flexible wireless network in order to narrow Digital Divide area with not much investment.
The configuration of the final system is shown in following diagram:
Where, GE- PON: Gigabit Ethernet- Passive Optical Network WHM: Watt Hour Meter EPCD: Electricity Power Consumption Data ONU: Optical Network Unit AMI: Advanced Metering Infrastructure
Page 3-2
Expansion of subscriber area can be either connection directly from Base Station or connection through repeater as following diagram:
3.2 Investigation Research In order to expand our idea in a future project, we have investigated the system at Ogawa village
which has low population and locate in Japan’s rural area (Kohchi Prefecture) so the investment of other communication infrastructure is not worth. Ogawa village uses this system for many services such as:
・ Internet service ・ Emergency Broadcast System ・ AM Radio Retransmitting service ・ Live broadcast of congressional discussion
The diagram of the system in Ogawa village is shown in following diagram:
This system uses combination of fiber optic and wireless network by using GEPON (fiber optic) to
provide communication from Ogawa Local Government Office to Base Stations which located all over
Page 3-3
village. The Base Stations then provide Last Mile communication to users by using wireless communication either by IEEE 802.11j or IEEE 802.11g and also can communicate with other Base Stations to provide multi-hop communication in order to increase coverage area.
Overall system configuration is shown in following figure:
