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 2.4 GHz spectrum and every
received symbol to provide you with
the most advanced RF analytics in the
industry.

Real-Time Reporting

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: waveform, waterfall,
and ambient noise level.

airView provides powerful spectrum
analyzer functionality, eliminating the
need to rent or purchase additional
equipment for conducting site
surveys.

airMAX ac TDMA Technology

Unlike standard Wi-Fi protocol,
Ubiquiti’s Time Division Multiple

Access (TDMA) airMAX ac protocol
allows each client to send and receive
data using pre‑designated time
slots scheduled by an intelligent AP

Datasheet

controller.

This time slot method eliminates
hidden node collisions and maximizes

airtime efciency, so airMAX ac

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.

Up to 100 airMAX ac stations can be connected to an airMAX ac Sector;

four airMAXac stations are shown to illustrate the general concept.

airMAX ac Network Scalability

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 signicant increase from

64QAM, which is used in airMAX.

With their use of proprietary
airMAXac technology, airMAX ac
products supports up to 330+Mbps

(maximum 40 MHz channel width)
real TCP/IP throughput – up to triple
the throughput of standard airMAX
products.

Technology

To enhance airMAX ac performance,
Ubiquiti Networks introduces our
patented airPrism technology, which
is featured on the Rocket 2AC Prism,

model R2AC-PRISM.

Improves SNR

High data rates require a high

Signal-to-Noise Ratio (SNR), which is

challenging to achieve, especially in
noisy, high‑density areas.

Integrated into Ubiquiti’s custom

silicon, airPrism technology creates a

high SNR by isolating signals within

the operating channel and rejecting
interference using specialized circuitry,

the High-Selectivity Receiver(HSR).

Removes Interference

Depending on the product model and
operating mode, available channel
widths may include 10, 20, or 40 MHz.

Theoretically APs operate on different
channels; however, because of the
wider channel bandwidths, there can
be overlap in spectrum usage.

airPrism technology removes up to an

additional 30+dB of adjacent channel

interference through the active

ltering design, so an airMAXac AP

with airPrism technology can provide

signicantly greater performance than

a typical AP.

Active Radio Frequency Filtering

Facilitates AP Co-Location

Co‑location is vital in many scenarios.

For example, a WISP may have limited

tower space, so it must co‑locate all
APs within that allotted footprint.

Shielding and other means can lessen

interference but may be impractical.

By deploying airMAX ac APs with
airPrism technology, you can
co‑locate APs and enhance the overall
performance of your wireless network.
