Line of Sight Considerations for Fixed Wireless Internet
In the realm of modern connectivity solutions, fixed wireless internet has emerged as a game-changer, offering high-speed internet access without the need for traditional wired infrastructure. However, the success of fixed wireless technology hinges on a critical factor: the "line of sight." In this blog, TERAGO explains what line of sight means in the context of fixed wireless internet, why it's crucial, and the considerations surrounding this requirement.

Understanding Line of Sight
Line of sight refers to the direct and unobstructed path between the fixed wireless transmitter (usually a tower or base station) and the receiver located at your premises. This pathway is pivotal for reliable communication as any obstructions (trees, buildings, or other structures) can hinder or even disrupt a signal.
Why Line of Sight Matters
The line of sight is crucial to the functioning of fixed wireless internet for several reasons:
Signal Strength: An unobstructed line of sight allows for stronger and more consistent signal transmission. Obstacles in the signal path can weaken the signal, leading to slower speeds and potential dropouts.
Signal Quality: A clear line of sight ensures minimal interference and signal degradation. Interference from physical obstacles can cause signal distortion and affect the overall performance of your connection.
Reliability: The line-of-sight requirement enhances the reliability of fixed wireless connections. Without obstructions, the risk of sudden signal loss is significantly reduced.

What are some barriers to Line of Sight for Fixed Wireless Internet?
Generally, the frequencies at which fixed wireless Internet systems operate require an 80% unobstructed line of sight to function properly. Natural or man-made stationary obstacles can interfere with this layout and block the radio signals. This can include:
1.??? Mountains
2.??? Trees

When considering fixed wireless internet for your location, there are several considerations related to line of sight:
Terrain: Assess the terrain around your premises. Hills or densely wooded areas might obstruct the line of sight, impacting a fixed wireless installation.
Obstacles: Identify any potential obstacles such as tall trees, buildings, or even hills.
Height and Elevation: The elevation of the transmitter and receiver antennas plays a role. Higher mounting positions can enhance the line of sight and potentially overcome certain obstacles.
Tower Placement: Research the location of nearby fixed wireless transmission towers. Proximity to a tower can increase the likelihood of a clear line of sight.
Professional Assessment: Consider getting a professional assessment from a fixed wireless provider. They can evaluate the line of sight and recommend suitable solutions if needed.
