Title:
RADIO SENSOR NETWORK
Document Type and Number:
Japanese Patent JP2019036816
Kind Code:
A
Abstract:
To provide a radio sensor network that is high speed and less likely to cause communication errors due to radio wave interference.SOLUTION: A radio sensor network includes one or more radio sensor modules and a gateway. Each radio sensor module includes: a first radio module for performing radio communication by using a first frequency band (2.4 GHz band); a second radio module for performing radio communication by using a second frequency band (920 MHz band); and a computation processing circuit for trying data transmission by using the first radio module, and performing control to switch to data transmission using the second radio module only when data transmission using the first radio module is failed.SELECTED DRAWING: Figure 3
