SENSOR NETWORK SYSTEM AND COMMUNICATION CHANNEL SETTING METHOD

Title:

SENSOR NETWORK SYSTEM AND COMMUNICATION CHANNEL SETTING METHOD

Document Type and Number:

WIPO Patent Application WO/2014/097874

Kind Code:

A1

Abstract:

This sensor network system (100) is equipped with: multiple sensor nodes (110) which are associated with smart meters; gateway devices (112) which collect data from the multiple sensor nodes and distribute data to the sensor nodes; and a center device (114) which receives data from the gateway devices and transmits data to the gateway devices. Radio communication is executed between the sensor nodes and between the sensor nodes and the gateway devices, and radio communication via a paid communication network is executed between the gateway devices and the center device.
