Quick Answer
To install fixed wireless internet, you'll need a clear line of sight to the tower or node, a compatible antenna, and a properly configured router. The tower or node should be within a specific distance, typically 5-10 miles, and the antenna should be installed at a precise height, usually 20-30 feet.
Choosing the Right Equipment
When selecting a fixed wireless internet system, consider the gain and beamwidth of the antenna. A higher gain antenna can increase signal strength, but may also narrow the beamwidth, requiring more precise aiming. For example, a 24 dBi antenna with a 30-degree beamwidth may be suitable for a suburban installation, while a 36 dBi antenna with a 10-degree beamwidth may be better for a rural area with multiple obstructions.
Installation and Alignment
To ensure a stable connection, the antenna should be installed at a height of 20-30 feet above the roof or a secure structure. The antenna’s azimuth (compass direction) and elevation should be carefully aligned with the tower or node, taking into account the local terrain and potential obstructions. Aiming the antenna too far off-axis can result in reduced signal strength and increased latency. A general rule of thumb is to aim the antenna within 1-2 degrees of the target to achieve optimal performance.
Network Configuration and Testing
After installing the antenna and connecting the equipment, configure the router and modem to match the settings provided by your internet service provider (ISP). This may include setting the IP address, subnet mask, default gateway, and DNS servers. Test the connection by pinging the ISP’s IP address and verifying the download and upload speeds. Troubleshooting may involve adjusting the antenna’s orientation, checking the signal strength, and ensuring a stable and clear line of sight to the tower or node.
