Ubiquiti PBE-5AC-400-ISO 5GHz 25dBi airMAX AC Bridge, RF Isolated

Overview
Ubiquiti Networks launches the PowerBeam^® ac ISO, an airMAX ac Bridge that is ideal for deployments requiring maximum performance and RF isolation.

Improved Noise Immunity
The PowerBeam ac ISO directs RF energy in a tighter beamwidth, and its integrated isolator design improves RF isolation to spatially filter out interference. With its combination of focused beam directivity and RF isolation, the PowerBeam ac ISO blocks noise to improve noise immunity. This is especially important in an area crowded with other RF signals of the same or similar frequency.

Integrated Radio Design
Ubiquiti’s 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.

Software

Advanced RF Analytics
airMAX ac devices feature 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 the most advanced RF analytics in the industry.
Data from the spectrum analysis and RF performance monitoring is displayed on the Main tab and airView Spectrum Analyzer of airOS V7.

Real-Time Reporting
The Main tab displays the following RF information:
• Persistent RF Error Vector Magnitude (EVM) constellation diagrams
• Carrier to Interference-plus-Noise Ratio (CINR) histograms
• Signal-to-Noise Ratio (SNR) time series plots

Spectral Analysis
airView allows you to identify noise signatures and plan your networks to minimize noise interference. airView performs the following functions:
• Constantly monitors environmental noise
• Collects energy data points in real‑time spectral views
• Helps optimize channel selection, network design, and wireless performance
airView runs in the background without disabling the wireless link, so there is no disruption to the network.
In airView, there are three spectral views, each of which represents different data.
• Waterfall Aggregate energy over time for each frequency.
• Waveform Aggregate energy collected.
• Ambient Noise Level Background noise energy shown as a function of frequency

Available with a firmware upgrade to airOS v7.1, airView provides powerful spectrum analyzer functionality, eliminating the need to rent or purchase additional equipment for conducting site surveys.

Technology
AirMAX ac
Unlike standard Wi-Fi protocol, Ubiquiti's 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.

Intelligent QoS Priority assigned to voice/video for seamless streaming.
Scalability High capacity and scalability.
Long Distance Capable of high‑speed, carrier-class links.

Superior Performance
The next-generation airMAX ac technology boosts the advantages of our proprietary TDMA protocol.
Ubiquiti's 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.

Throughput Breakthrough
airMAX ac 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, airMAX ac products supports up to 450+ Mbps real TCP/IP throughput – up to triple the throughput of standard airMAX products.


Hardware Overview
Innovative Mechanical Design
• Metal-plated interior of rear housing Enhances RF shielding.
• Built-in mechanical tilt The mounting bracket offers ± 20° of tilt.
• Convenient pole-mounting Only a single wrench is needed to mount the PowerBeam ISO on a pole.
Industrial-Strength Construction
• Fasteners GEOMET-coated for improved corrosion resistance when compared with zinc-plated fasteners.
• Dish and brackets Made of galvanized steel that is powder‑coated for superior corrosion resistance.
• Protective radome Shields the radio from nature's harshest elements.

Breakthrough RF Isolation
The integrated isolator design spatially filters out interference, so the PowerBeam ISO delivers improved noise immunity in co-location deployments.
Compare the two near-field plots below, and note the superior performance of the integrated RF isolator.
Both near-field plots are displayed in watts and use a linear scale. The strength of the electromagnetic field is color-coded:
• Red: Highest strength
• Green: Medium strength
• Indigo: Lowest strength
