Overview

Aimed at creating an ecology-minded ubiquitous society with assured safety and security, the wide-area ubiquitous network provides a “bi-directional communication service with objects” that is omnipresent everywhere. The system provides the bi-directional communication service in a wide range of utilization environments both indoors and outdoors. Furthermore, it can connect terminals that have up till now been difficult to apply with conventional wireless systems (e.g., mobile phones and wireless LANs) to the network.

We have built a test environment at the “specified ubiquitous district” of the Ministry of Internal Affairs and Communications in Tokyo, and have carried out the technical verification and service validation in collaboration with partners.

Features

  • Long-term “maintenance-free” wireless terminals through low-power operation
  • A large cell size through supplementing functional capability of wireless terminals with that of base station
  • Efficient integration of the very-short-packets characteristic of communication with objects
  • Compatible with signal-processing capability and high security needed for wireless terminals

Application scenarios

  • Remote-reading services for consumed quantity of gas, water, etc. supplied by public-utility infrastructure
  • Environmental-monitoring services practically applicable as environmental-protection and energy-saving measures
  • Elderly-people and child-monitoring services for supporting the aging society with fewer children
  • Physical distribution and asset-management services that understand the whereabouts of “objects” and their mobile history
  • Status-checking and monitoring services for infrastructure installation and maintenance
