The Making Of AirFiber
Featuring a dual-independent 2×2 MIMO 24GHz hi-gain reflector antenna system, airFiber can operate in both FDD (Frequency Division Duplex) and HDD (Hybrid Division Duplex) modes for unparalleled speed and spectral efficiency in the 24GHz worldwide license-free band.
The Making Of AirFiber
Introducing airFiber®, a truly revolutionary Point-to-Point wireless platform from Ubiquiti Networks™. Housed in a compact, highly efficient form factor, airFiber delivers amazing wireless gigabit+ performance, low latency, and long range. airFiber ushers in a new era in price-disruptive wireless technology ideal for carrier backhaul, building-to-building enterprise use, or public safety applications.
Every detail of airFiber was designed and engineered by the Ubiquiti R&D Team. From the silicon chip up to the innovative split-antenna architecture, the Ubiquiti R&D Team created airFiber to deliver superior throughput with efficiency. airFiber was purpose-built to create a high performance backhaul.
Based on Ubiquiti’s innovative and intuitive airOS®, the airFiber Configuration Interface enables quick deployment. With installation efficiency in mind, the mechanical design allows easy installation by one person. A two-person installation crew can effectively install and align an airFiber link.
To fine-tune the alignment, the received signal levels can be conveniently accessed via any of these methods:
• airFiber LED display
• airFiber Configuration Interface
• Audio tone feature
AirFiber operates in worldwide, license-free, 24 or 5 GHz frequencies. Anyone around the world can purchase and operate airFiber without any special permits, paperwork, or added licensing costs. Users are free to locate, deploy, and operate airFiber practically anywhere they choose (subject to local country regulations).
airFiber delivers gigabit performance at 1.0+ Gbps for airFiber AF5/AF5U and 1.4+ Gbps for airFiber AF24. To put this in perspective, airFiber can transmit a 100 MB file in less than a second. Rivaling common broadband providers, airFiber download speed is up to 100x faster. With speed and throughput surpassing conventional wired backhauls, airFiber prevails over expensive and labor-intensive wired infrastructures.
Ubiquiti’s innovative proprietary modem technology was purpose-built to address the specific challenges of outdoor, PtP (Point-to-Point) bridging and high-performance network backhauls. Every aspect of the radio has been carefully simulated and designed to optimize range, speed, and latency performance in the harshest RF noise environments.
Conventional wireless standards impose a latency by having to receive a packet before a packet is transmitted. airFiber can transmit data synchronously without any wait time. airFiber features traditional TDD and FDD modes of operation in addition to the proprietary Hybrid Division Duplexing (HDD) mode, which provides a breakthrough in range and spectral efficiency performance. Based on the ranging algorithm built into the air protocol, the airFiber radios use patent-pending HDD technology to calculate the propagation delay and know when each radio can transmit and receive, so they send packets in precise synchronization. Packet transmission latency is virtually eliminated.
airFiber features a dual-independent, 2×2 MIMO, high-gain reflector antenna system. Separate transmit (TX) and receive (RX) antennas help extend link budgets by eliminating the extra RF losses caused by the switches or duplexers required in systems with common TX/RX antennas. Each airFiber radio has two complete antenna systems and a mechanical back-plane that are constructed as a one-piece “monocoque” molding – a radical departure from industry practice. “Monocoque” means that the exterior skin supports the structural load of airFiber hardware. Due to its single-piece, injection-molded architecture, airFiber adds lightness in weight and affordability to its list of advantages.
airFiber supports a variety of features to help you manage your network: • Network management options A choice between the greater security of out-of-band management and the convenience of in-band management. • SNMP support Full SNMP support to aid in network management. • Local and remote airFiber status information Available on the Main tab of the airFiber Configuration Interface.
