Optical wireless communication system

A optical wireless communication system for constituting a bilaterally communicating network comprising:

• a plurality of optical repeaters having a function to switch information frames, and
• a mobile optical node bilaterally communicating with said optical repeaters, wherein:
• information frames including address information of said optical node are periodically transmitted from an information processor connecting said optical node to said optical repeaters via wireless optical transmission;
• said address information is continuously transmitted from said optical repeaters to a trunk network, and
• a filter function is arranged so as to make only one frame effective among frames with the same content.

A optical wireless communication system communicating network comprising:

• a mobile optical node;
• a plurality of optical repeaters bilaterally communicating with said optical node, and
• a transit post for connecting said optical repeaters to a trunk communication network, wherein:
• a bilateral network system is attained by a optical wireless communication.

A transit post for connecting an optical repeater which has a function to switch information frames and is capable of optical bilateral communication with a mobile optical node, wherein:

• said transit post comprises:
• a filter unit for passing one frame with the same content from said repeater among information frames;
• an administration table for registering and administrating addresses of the information frames on said optical repeater and said optical node;
• and
• a frame sorting unit for refusing the passed frame when an FCS data of the frame is the same as a receiving refusal FCS data.
