N-SPOI is the industry's only third-party, vendor-agnostic DAS Point-of-Interface designed to deliver exceptional performance optimized for low power radio environments. N-SPOI's compact footprint, flexibility, scalability, intuitive GUI, remote control and monitoring capabilities set the new standards in DAS POI.
Its modular design accommodates up to eight (8) 2x2 MIMO RF cards in a 19" 3RU chassis, allowing mix-and-match across all bands. Add more cards as your system grows.
Purpose-built for low power radio environments, N-SPOI delivers exceptional performance at 5W / 37dBm power rating with TX input range from 0 to +37dBm across both 2.2-5 and SMA radio connections.
Every RF card is a native 2x2 MIMO card - no external combining or splitting required. Eight card slots mean up to eight MIMO bands in a single 3RU chassis.
Supports both 4G and 5G deployments across FDD and TDD schemes, covering all major bands from 600MHz up to C-Band (3450-3980MHz).
Choose between 110VAC (NS-MFCA) or -48VDC (NS-MFCD) chassis to match your site's power infrastructure without additional converters.
Intuitive web-based GUI for remote configuration and monitoring, with SNMP V2C and V3 alarm support for integration into enterprise NMS platforms.
Independent TX (0 to 20dB) and RX (0 to 45dB) attenuation in 0.5dB steps with ±1.5dB accuracy, plus 15dB LNA gain on FDD cards for uplink performance tuning.
N-SPOI's DAS Interface allows Simplex and Duplex to be selected in the GUI, so it can be selected to match the DAS Interface.
