In indoor areas where radio waves are difficult to reach and in dead zones, radio waves are transmitted via optical fiber, connecting to multiple antennas through several photon devices to enable wireless communication.
We would like to introduce a case where the "Airport DAS System" was implemented in transportation wireless equipment. The Optical DAS System (Optical Fiber DAS, Distributed Antenna System, Optical Repeater) is an optical transmission system designed for countermeasures against dead zones, aimed at increasing the number of lines and functionality. It has scalability at the unit level, making it easy to expand the wireless area. By operating in conjunction with monitoring applications using Ethernet, it allows for the monitoring of equipment in operation, and in the event of an anomaly, it also has a reporting function that sends notifications to registered users via email. 【Case Overview】 ■ Installation Location: Public Social Infrastructure (Major Domestic Airports) ■ Installed Product: Airport DAS System *For more details, please refer to the related links or feel free to contact us.
