Ubiquiti Networks has recently announced the launch of their upper 4GHz licensed spectrum radio: the airFiber 4X which is specifically designed for the public safety sector. It meets the growing need of broadband capacity and optimizes the use of the 4.9 GHz radio band with its industry-leading spectral efficiency and proprietary Hybrid Division Duplexing (HDD) technology. The AF-4X allows you to customize airFiber backhaul links or upgrade existing Rocket Point-to-Point (PtP) links.

Public Security Sector

With Ubiquiti AirFiber 4X you can now build networks for national security services and public protection. This is a space normally occupied by expensive traditional wireless equipment. The AirFiber 4X brings affordability to the government licensed space, enabling you to deliver a high capacity network specifically for national security.

Please note: the use of upper 4GHz is strictly for national security applications and must be approved by the licence holder (local government). 

What else does the AF-4X offer? 

4GHz Backhaul

• Engineered for Performance

Ubiquiti’s INVICTUS™ custom silicon and proprietary radio architecture is designed specifically for long-distance, outdoor wireless applications. Their INVICTUS core communications processing engine surpasses all of the limitations inherent to generic Wi-Fi chips to provide superior performance, long-range capability, and higher delivered throughput.

The airFiber X features industry-leading spectral efficiency of up to 17.1 Mbps/MHz, line rate data packet processing of up to 525 Mbps of real data throughput, and innovative xtreme Range Technology (xRT™) for communication over distances of up to 200+ km.

• Mission-Critical Communications

Since the AF-4X is specifically designed for public safety applications it uses a proprietary radio communications protocol with AES-128 encryption to help ensure network security of the highest level.

• Ultra-Low Latency with HDD Technology

The AF-4X is designed to provide the highest TDD throughput and lowest latency available using proprietary Hybrid Division Duplexing (HDD) technology.

• Optimal Operation and Channel Configuration

The AF-4X supports up to 11 different channel width sizes* to suit your deployment needs. You can configure independent TX and RX channel frequencies and place them anywhere within the radio band, and the channel centres are selectable in 1 MHz increments. You also have the ability to program different uplink and downlink duty cycles to support asymmetric traffic requirements.

* Channel widths may vary according to country/region regulations.

Co-Location

With space at a premium, the importance of being able to colocate equipment is becoming an essential attribute for modern wireless networks. The AF-4X is engineered to permit multiple radios to operate side by side, allowing maximum spectral efficiency.

• GPS Synchronization

Precise GPS frame synchronization enables co-located AF-4X radios to transmit and receive data without interfering with each other, enabling better frequency reuse and increased network stability.

• Clean Power Output

Using advanced digital signal processing, the innovative AF-4X radio design has an ultra-clean transmitter output, reducing broadband noise, facilitating co-location, and enabling higher order modulations like 1024QAM for greater throughput.

Deployment Flexibility

The AF-4X supports ± 45° slant polarization for improved noise immunity and Signal-to-Noise Ratio (SNR). The compact form factor of the airFiber X allows it to fit into the radio mount of Ubiquiti antennas, so installation requires no special tools.

• The airFiber X antennas are purpose-built with 45° slant polarity for seamless integration with the airFiber AF-4X.
• You can also pair the AF-4X with one of the following RocketDish™ antennas by using a kit to convert the RocketDish to 45° slant polarity
• The RocketDish to airFiber Antenna Conversion Kit converts the RocketDish RD-5G30 or RD-5G34 antenna to 45° slant polarity for use with the AF-4X.
• Pair the AF-4X with the UBAF-5G34-S45 slant dish, the UBAF-5G30-S45 slant dish, the UBAM-5G30D-RA rocket dish or the UBAM-5G34D-RA rocket dish.
