Can point-to-point systems work for off-grid cabins?

System Design

Point-to-point wireless internet systems can be an ideal solution for off-grid cabins, especially when there’s a clear line of sight between the two locations. For example, using Ubiquiti equipment, a long-range bridge can be established between the cabin and a nearby location with internet access. With a high-gain antenna (around 24 dBi) and a strong transmitter (up to 1 W), a distance of up to 10 miles (16 km) can be covered, depending on the terrain and environmental conditions.

Installation Considerations

When designing a point-to-point system for an off-grid cabin, it’s essential to consider the installation’s complexity and cost. Factors such as the terrain, elevation, and weather conditions can affect signal strength and reliability. In some cases, it may be necessary to install a tower or mount the equipment on a rooftop or mast to achieve a clear line of sight. The choice of equipment and installation should be guided by the specific needs and conditions of the off-grid cabin.

Technical Details

To ensure a reliable and high-speed connection, it’s crucial to choose the right equipment and configure it correctly. For example, using a Ubiquiti EdgePoint or airMAX device, with a 24 GHz or 5 GHz frequency, can provide high-speed data transfer rates (up to 1 Gbps). It’s also essential to configure the system for optimal performance, including adjusting the transmit power, modulation, and coding, as well as setting up Quality of Service (QoS) and bandwidth management.
