Overview
Sector Coverage
The airMAX Sector Antenna is a
Carrier Class 2x2 Dual Polarity MIMO
Sector Antenna that was designed to
seamlessly integrate with RocketM
radios (RocketM sold separately).
Pair the RocketM’s radio with the
airMAX Sector Antenna’s reach to
create a powerful basestation. This
versatile combination gives network
architects unparalleled flexibility and
convenience.
On the right is one example of how
the airMAX Sector Antenna can be
deployed:
Utilize airMAX 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 efficiency. It provides
many magnitudes of performance
improvements in latency, throughput,
and scalability compared to all other
outdoor systems in its class.
Intelligent QoS Priority is given to
voice/video for seamless streaming.
Scalability High capacity and
scalability.
Long Distance Capable of
high-speed, carrier-class links.
* When airMAX Sector is paired with RocketM
airMAX Sector Antennas provide sector-wide coverage and utilize
airMAX technology to produce carrier-class performance and power.
Up to 100 airMAX clients can be connected to an airMAX Sector;
four airMAX clients are shown to illustrate the general concept.
