How Does a DAS Point of Interface Work?

RF signals from different operators, technologies or frequency bands enter the POI through dedicated input ports. Inside the unit, the signals are filtered and combined according to the specified frequency plan. The combined output is then connected to the shared passive DAS feeder network, where power splitters, directional couplers and tappers distribute the signal to indoor antennas.

Monitoring ports, attenuation stages and termination loads may also be included to support commissioning, signal balancing and safe operation.

Why Need A Point-of-Interface?

01

Interoperability

It allows different networks or systems to work together by establishing standardized connection points. This is essential for ensuring that services from different providers or technologies can communicate effectively.

02

Efficiency

By having a clear and defined interface, network operations can be streamlined. This makes it easier to manage and troubleshoot connections, reducing downtime and operational complexity.

03

Scalability

A well-defined POI can facilitate network expansion and upgrades. As new services or technologies are introduced, they can be integrated more smoothly at the interface, allowing the network to grow and evolve efficiently.
