Wireless communication system using a waveguide |
摘要 |
The communication device for transmitting signals between the substations control unit (4) and the control units (3) of the bay elements (1) comprises transceiving devices (6, 7) connected to the substation and the bay element control units (3), and a wave guide (5) enclosing and connecting antennas (9) of said transceiving devices. The transceiving devices (6, 7) produce electromagnetic radio frequency airwaves to communicate information between the control units. The wave guide (5) protects the waves against interference (12). <IMAGE> |
