This article provides some guidance on what products are ideal for different purposes. Once the CPU code takes over, the MIMO, LINK, and Signal 1-3 LEDs turn off.

Devices must be professionally installed and it is the professional installer’s responsibility to make sure the device is operated within local country regulatory requirements. In order to achieve certain modulation, enough signal strength is necessary to keep it stable. In fixed outdoor wireless communications there are two primary deployment methods used for distributing wireless: Point-to-Point (PtP), and Point-to-Multipoint (PtMP). Lower frequencies have better propagation characteristics than higher frequencies, and may work better in environments where Line of Sight is obstructed (by trees for example). The airFiber ® 5 supports FDD (Frequency Division Duplexing) in full-duplex mode for 1 ms latency, resulting in increased efficiency for carrier-class network backhauls. airFiber 5 and 5U: Ideal superior performance in the 5GHz band, the airFiber 5/5U delivers up to 1.2Gbps in the 5GHz band. The links above are just some examples, you can find current airMAX antennas on this page by scrolling down to the antenna section. The following suggestions are based on reference distances.

Below is a diagram of a finished installation with recommended surge protectors installed. Failure to do so may result in damage to the Duplexer. airFiber backhauls do not share the security risks associated with wired backhauls. They provide high gain amplification of the signal power resulting in higher signals and better link quality. Only three non-overlapping 20MHz channels (1, 6, 11), It’s a very crowded band; there’s a lot of interference from cordless phones, SOHO Wireless Router, other WISPs, etc…, 300MHz bandwidth in countries where 3.4-3.7GHz band is available, Only 25MHz bandwidth in countries where 3.65GHz can be used, Higher EIRP limits allow higher gain antennas, and long distance links, Large amounts of spectrum available, easier to co-locate nearby devices, Weaker propagation vs. lower frequencies when obstacles are present (trees, walls, etc.). However, not all users know that the output power also determines what the maximum modulation rate is. Ubiquiti’s proprietary protocol enables time-synchronous packet transmission, resulting in the lowest possible, sub-millisecond latency – vital for backhaul performance.

However, these bands may also have higher levels of noise and interference, so it's important to select the frequency that works best in your situation. 685 Third Ave. 27th Floor New York, NY 10017, Visit our worldwide community of Ubiquiti experts for more answers, Ubiquiti Networks Support and Help Center. Radio sensitivity depends on channel width and modulation, for example if you want to get 8X modulation using 30MHz channel you need a received signal strength of -62dBm or better (like -60dBm, -55dBm, etc...). Note: Maximum signal strength can best be achieved by iteratively sweeping through both azimuth and elevation. Adjust the positions of the Master and the Slave to establish a link. airMAX and airFiber both have different product options to cover a multitude of different outdoor wireless scenarios. (Recommended) Surge protection should be used for all outdoor installations. Failure to do so can damage the unit and void the product warranty.
Note: One Low-Band Duplexer or High-Band Duplexer is pre-installed in the radio for SISO mode. Usually located on the top of a tower, building or mast. 2Channel widths may vary according to country/region regulations.

Rivaling common broadband providers, airFiber download speed is up to 100x faster. Categories * WORK FROM HOME * The airFiber NxN is designed for use with the airFiber 4X and 5X (AF-4X/AF-5x) radios or RocketDish antennas. If you are using DC power, connect the other end of the Ethernet cable to your LAN. Please Call 866-891-3602 for Availability.

In SISO mode, these unused ports are protected by the Duplexer Cap. Note: For example, if the numbers on the first radio’s Duplexers are (left to right) 2/4 and 4/2, the numbers on the second radio’s Duplexers should be 4/2 and 2/4. 2020 DoubleRadiusSM - All Rights Reserved.

airFiber delivers gigabit performance at 1.2+ Gbps for airFiber AF-5/AF-5U, 1.5+ Gbps for airFiber AF-24, and 2 Gbps for airFiber AF-24HD. Noise-free in most cases, very useful when the 5.8GHz band is crowded. Also, ensure that the numbers on the right-side Duplexer are in the reverse order of the numbers on the left-side Duplexer. For instructions on how to access the Duplexers and remove or install them, see “MIMO Mode Installation”. High gain antennas play an important role in high performance outdoor wireless for two main reasons. Fine-tuning is best achieved by a pair of installers with a dedicated, two-way communication link: one installer makes adjustments on one airFiber radio while the other installer reports the received signal level at the other airFiber radio. Female N-type connector to which the antenna cable is attached. For MIMO mode, a second Duplexer is available, model AF-11-DUP-L or AF-11-DUP-H. WARNING: Tighten the collars alternately, a half turn at a time, until both are fully tightened. For example, if the link has a 1 dB loss, the Signal 4 LED will flash; a 2 dB loss and the Signal 4 LED will turn off. Note: The ground wire should be as short as possible and no longer than one meter in length. It meets the growing need of broadband capacity and optimizes use of the 4.9 GHz radio band with its industry-leading spectral efficiency and …

Note: For SISO mode, use the RF connector (H or V) as determined by your licensing.

Each AF-11 radio already contains one Low-Band Duplexer or one High-Band Duplexer for SISO mode.

We recommend that you use two Ethernet Surge Protectors, model ETH-SP-G2, one within one meter of the device and the other at the entry point to the building. The Community: the airFiber Community forum is filled with experts from all over the world who have real life experience with functioning airFiber deployments. Pair the AF-5XHD with a compatible Ubiquiti® airFiber X antenna or RocketDish™ antenna for a complete 5 GHz Point-to-Point (PtP) solution. However, before you install the radios, you must ensure that Duplexers in the paired radios are positioned in the reverse order from each other. Configure the Ethernet adapter on your computer with a static IP address on the 192.168.1.x subnet. Better tolerance for trees and small obstacles vs. higher frequencies. WARNING: Failure to properly ground your airFiber radio will void your warranty. For detailed information on setting up an airFiber link, see the airFiber AF-11FX User Guide available at: ui.com/download/airfiber. And they are highly directional, which gives them spatial filtering characteristics that can help to block noise.

Each frequency has different characteristics due to physics and utilization. Gigabit PoE port for handling all user traffic and powering the device. Now based in New York City, Ubiquiti manufactures wireless data communication products for enterprise and wireless broadband providers with a primary focus on under-served and emerging markets. In-Band Management is enabled by default in the airFiber Configuration Interface. Check to see if a link is established. Note: Do NOT make simultaneous adjustments on the Master and Slave. Note: The airFiber Configuration Interface supports IPv6 formats excluding dotted quad and “::” (double-colon) notation.
Bootup to airOS When powering on, the Power, MIMO, LINK, and Signal 1-4 LEDs light on. This continues until the device is fully booted. Note: Align the dot on the side of the shroud with the arrowhead on the dish antenna. Radio sensitivity information is available in our products' datasheets (found in our Downloads page). Connect the DC power supply to its source. There is a very high chance that they have already faced the issue you are seeing now, as well as having experience in third-party devices that might have some influence in the issue. Initializing airFiber Software When the airFiber application begins to boot under airOS, the Signal 4 LED goes from solidly on to a 2.5 Hz flash. Each Signal LED has three possible states: On, Flashing, and Off. Clear line of sight between airFiber radios, At least 1 m below the highest point on the structure, For tower installations, at least 3 m below the top of the tower, (Optional) If not using PoE: DC power source and 12/30 AWG power cable. Follow the instructions for the source of power that you are using: WARNING: Applying a negative voltage such as -48VDC will damage the radio.

* Cable Loss includes loss due to the Duplexer(s).

Access the airFiber Configuration Interface and configure the following settings: Note: One airFiber radio’s TX Frequency is the other radio’s RX Frequency, and vice versa.
