Silent Box

Summary

Provides anechoic boxes suitable for research and development, testing, and adjustment of the next generation wireless communication systems.

Features

Enables good reproducibility as a distance of more than 3 λ is secured between the receiver and the transmitter. Available for adjusting or testing antenna measuring wireless devices.

Application examples for microwave R&D

  • Cellular antennas
    (Surface/Satellite waves (IMT-2000)) (0.8 to 2.2 GHz)
  • Stationary satellite communications (GPS) (1.5 GHz -/5.1 GHz-)
  • Wireless LAN (2.4 GHz-/5.1 GHz-/19.3 GHz-)
  • Automatic toll collection systems (ETC-electronic toll collection system) (5.6 GHz-)
  • Satellite broadcasting (BS/CS) (11.7 GHz-)
  • Intelligent Transport Systems (ITS) (60 GHz)
