The 5-pack of PBE-5AC-400 PowerBeam ac ISO 5 GHz airMAX ac Bridges from Ubiquiti Networks directs RF energy in a tighter beamwidth. With the focus in one direction, the PowerBeam ac blocks or spatially filters out noise, so noise immunity is improved. This feature is especially important in an area crowded with other RF signals of the same or similar frequency.

InnerFeed technology integrates the radio into the feedhorn of an antenna, so there is no need for a cable. This improves performance because it eliminates cable losses. This device features a multi-radio architecture to power a revolutionary RF analytics engine. An independent processor on the PCBA powers a second, dedicated radio, which persistently analyzes the full 5 GHz spectrum and every received symbol to provide you with advanced RF analytics.

Data from the spectrum analysis and RF performance monitoring is displayed on the Main tab and airView Spectrum Analyzer of airOS V7. The Time Division Multiple Access (TDMA) airMAX protocol allows each client to send and receive data using pre-designated time slots scheduled by an intelligent AP controller.

This time slot method eliminates hidden node collisions and maximizes airtime efficiency, so airMAX technology provides performance improvements in latency, noise immunity, scalability, and throughput compared to other outdoor systems in its class. The airMAX engine with custom IC dramatically improves TDMA latency and network scalability. The custom silicon provides hardware acceleration capabilities to the airMAX scheduler, to support the high data rates and dense modulation used in airMAX ac technology.

The bridge supports high data rates, which require dense modulation: 256QAM – a significant increase from 64QAM, which is used in airMAX. With their use of proprietary airMAX ac technology, the bridge supports up to 450+ Mb/s real TCP/IP throughput.
