the antenna interface. This allows the maximum available RF power for any application.
 PIM-Free, VSWR free Installation
The IRU-O assembly is factory tested for PIM and VSWR. This eliminates the possibility of facing
PIM or Return Loss issues related to mismatched components and poor installation practices. This
significantly improves installation and commissioning time.
 Low Noise Figure and Low System Noise Rise
The IRU-O features a lower noise figure than traditional remote units, that combined with the
distributed active architecture provides a significant improvement in DAS noise rise and SNR
compared with high power traditional solutions with passive distribution. The combination of which
can improve KPI’s and throughput.
 Fault Tolerance
The active distribution architecture of RADiAnt provides fault tolerance. In the event that one
remote unit fails, only a single antenna/coverage area is affected. In a traditional solution with high
power DAS and passive distribution, if the remote unit fails, an entire group of antennas is down
affecting the service in a much larger area.
 Easy Installation and Low Project Cost
Radiant is much more than replacing coax with fiber, the core network (IM2U and NEU) will only
deal with the signal processing and covert RF signals to fiber signals and transmit over fiber with
very small loss and no increased noises, and the network extender unit (NEU) only use hybrid cable
(integrated cable with power and fiber) to connect IRU-O, each NEU can connect 16 pieces IRU-O,
it means that save project time and cost.
