How to Get the Most Out of Airlink Unifi

With Airlink Unifi, you will always have unlimited, hassle-free internet. The service is billed on a monthly basis, with no contracts and no usage limits. What’s more, it’s completely void if you ever want to stop using it. Read on for more information. Here, we’ll cover Line of sight, Fresnel zones, antenna height and gain, and how to get the most out of Airlink Unifi.

Line of sight

A wireless network operator should check a number of factors to ensure a good connection. Depending on the type of wireless network, line of sight and the first Fresnel zone are crucial. The antenna height, gain, and output power can be adjusted accordingly. The height of the antenna can be difficult to determine, particularly in remote settings. A smaller tower is more suitable for the installation, and one that is under 15 meters is more manageable. The dish should have a height of about 10 meters or less.

Fresnel zones

If you’re flying on an airlink UniFi network, you’ve probably noticed that Fresnel zones appear on the graph. These zones are elliptical shapes centered on the transmitter and receiver. When a Fresnel zone is obstructed, the link will perform at reduced speed. However, the loss of the signal depends on the type of material.

Basically, a Fresnel zone is a series of confocal prolateellipsoidal regions in space. The name comes from physicist Augustin-Jean Fresnel. When a direct line-of-sight wave travels through a Fresnel zone, the stray transmitted waves will follow different paths. These aberrant waves arrive out of phase with the primary wave because of their different path lengths.

Antenna height

One of the important components of an indoor WiFi network is the antenna. There are a few ways to increase the antenna height, including adding a mast or antenna bracket to the building. If your building is a metal structure, you may need to add a tower or antenna bracket. The height of the antenna must match the estimated signal from the ISP Design Center. Any deviation can lead to a signal discrepancy of 2 or 3 dB, or it can obstruct the Fresnel Zone. Ideally, antennas should be mounted as high as possible, with a clear line of sight.

To get a clear Line of Sight and good signal strength, use the contour maps to determine the optimal height. Ensure the access point is above any reflective surfaces and is at least two to three meters off the ground. The height should be positioned at an optimal angle with the direction of the AP. Ensure the client CPE is placed on high ground and is pointing in the direction of the AP.

Antenna gain

Antenna gain is a critical feature when using the AirLink WiFi system. It determines the amount of power a device can transmit and receive at a given location. The amount of power a device can receive is directly proportional to the antenna gain. Depending on the channel width and total EIRP of a wireless router, an antenna can significantly increase or decrease the signal strength.

Output power

The AirLink is a wireless access point that can predict the throughput and distance between two stations. The device is Ofcom-compliant, but its maximum output power is still less than the theoretically recommended limit of 23 dBm (200 mW). It works on two different frequency bands: Band A for short-range and lower-powered applications, and Band B for long-range and higher-powered applications.
