Do geographical features impact the effectiveness of goTenna Mesh?

Topography and Obstacles

goTenna Mesh relies on line-of-sight communication to establish and maintain network connectivity. Features such as hills, valleys, or bodies of water can block or attenuate signals, reducing the effective range and reliability of the system. For example, a 30-meter hill can block signals from devices on the other side, while a dense forest can reduce signal strength by as much as 90%.

Urban Environment and Canyons

Urban areas with tall buildings or narrow alleys can create “urban canyons” that significantly reduce signal strength and range. In such environments, goTenna Mesh devices may struggle to establish connections or maintain a reliable network, particularly if the devices are located in deep, narrow canyons. Techniques such as using higher-gain antennas or installing devices on rooftops or high-rise structures can help mitigate these effects.

Terrain Features and Obstacles

Terrain features such as rocky outcroppings, bridges, or overpasses can also impact goTenna Mesh performance. In such cases, using antennas with a wider beamwidth or installing devices in areas with unobstructed views can help maintain signal strength and range. Additionally, using techniques such as signal boosting or repeating can help extend the effective range of the system in areas with significant obstacles.
