Technology
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 efciency, 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 signicant 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.
