SmartCoupler

SmartCoupler Monitoring System

Microlab, celebrating 70 years of service with a global reputation for high quality PIM rated passive devices is proud to release its patent-pending SmartCoupler. Unlike commercial wireless cellular distributed antenna systems (DAS), conventional two-way, push-to-talk, public safety radio DAS does not have constant network traffic. Critical communication systems carry radio traffic only during an incident. Specialized directional couplers are combined with IoT circuitry and powered over the coaxial cabling from a headend gateway unit. The gateway also provides the diagnostics and communications to and from each SmartCoupler throughout a building. Through a graphical user interface, system integrator, authorities with jurisdiction, and or building owners may connect to the gateway locally or via the internet to continuously monitor the in-building, emergency first responder DAS network. The output of a building’s RF bi-directional amplifier i.e. booster or control head/repeater combination is connected to the gateway’s RF input. Original signal integrity is maintained, and the DAS is fed from the RF output. At specified intervals the gateway communicates with each SmartCoupler within a building by sending and receiving diagnostic signals. The SmartCoupler replaces the required tappers and couplers that are typical in a passive DAS and may be ordered with 6, 8, 10, 15, and 20 dB forward power coupled ports.
