The Active SYM Point of Interface (ASPOI) is the preferred 3rd party DAS POI due to its innovative approach to remotely manage and monitor the DAS systems power levels via its intelligent and intuitive GUI.
Its modular design allows mix-and-match of different band cards. You can add more cards as you go.
It handles up to 48dBm on High Power Mode and 38dBm on Low Power mode which allows for a lower insertion loss for low power radios of only 2~3.5dB
With integrated CW tone generation, it streamlines CW test procedures without walkie-talking between two installers, significantly reducing DAS commissioning time.
In the event of power failure, it bypasses to “Safe Mode” to ensure continuous service. The downlink path will maintain its attenuation levels with no change, and the uplink will default to 7.5dB insertion loss.
Each card has a physical monitoring port for both uplink (8dB coupling) and downlink (31dB or 41dB coupling), eliminating the need to put external couplers.
With a single click of the mouse, users can download the entire daisy chain as-built report for site commissioning.
One connection (One IP) gives you bird’s-eye view of all daisy-chained units (One as a Host and the other 14 as Remotes)Allows multi-user access with different access rightsWeb-based GUI and no proprietary software required.
It produces graphic charts for each card’s downlink input power changesPower level is measured every hour. Results are stored, analyzed and charted for one year worth of data.

User Interface design is so intuitive that we don’t believe one would need to read the user manual to set up and maintain the active SPOI. – When you daisy chain the units, remote units are automatically recognized and registered in the Host unit.
