Proposing the use of "Optical Wireless Communication" in plant IoT

We would like to shift to wireless, but we are concerned about noise interference from the production facility and information management.

TAIYO YUDEN's "Optical Wireless Communication"
  • Provides a communication method that is not affected by mechanical noise and wireless interference
  • Enables secure, wireless plant communication
  • Low delay (latency: 0.01 ms)
  • Communication costs are not required, wireless that does not need to be certified

Speed delays due to communication methods


Radio wave interference and jamming do not occur (LED usage)
Overwhelmingly low delay (latency: 0.01 ms)
