Apex Custom POI Solutions

POI (Point of Interface), also known as coupler cabinet or combiner, is a core device in RF indoor coverage systems. By filtering and combining multiple RF signals from different operators and systems into a single output, it enables multiple networks to share one indoor distribution infrastructure — cutting deployment cost and complexity while ensuring reliable transmission for cellular, LTE and private trunking services.

Apex POI feature high power handling and low Passive Intermodulation (PIM) to minimize signal interference, making them ideal for dense 5G environments. The ruggedized, waterproof design withstands extreme temperatures, humidity, dust, heavy rain and blizzards, for both indoor and outdoor deployment.

Leveraging years of expertise in RF passive component integration, Apex delivers end-to-end customization: multi-band support from 700MHz to 3.5GHz across 2G/3G/4G/5G and multi-operator combining; flexible port count and connector types (N-type, DIN, 4.3-10); custom dimensions and mounting options (wall, rack, pole) for confined spaces; and tailored PIM, insertion loss and isolation per requirement.

Deployed in commercial complexes, transportation hubs, metro tunnels, mining and industrial facilities, telecom towers and highway corridors, Apex POIs resolve weak signal and dropout issues in enclosed spaces, delivering uniform coverage.

Whatever your project requires, our professional RF engineering team provides tailor-made POI solutions with high-quality products and full technical support.
