UBNT-AIRMAX-SEC-3G-120-18
airMAX® 2×2 BaseStation Sector Antenna Pair the airMAX® Sector Antenna with a Rocket™M BaseStation for sector coverage in Point-to-MultiPoint (PtMP) networks.
The airMAX sector Antenna is a Carrier Class 2×2 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 powerfull basestation. This versatile combination gives network architects unparalleled flexibility and conveniance. Unlike standard WiFi protocol, Ubiquiti‘s Time Division Multiple Access (TDMA) airMAX protocol allows each client to send and receive data using pre-designated time slot sheduled 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.
