Sail equipment is unlikely to interfere with your WiFi router. Some Sail equipment uses frequencies in the 5 GHz band, which WiFi routers also use, but the two are designed to avoid interfering with each other.
Sail’s rooftop equipment is aimed away from your home’s interior. Sail’s radios are mounted on rooftops and use directional antennas that send and receive signals only in specific directions toward other points on our network. Very little of that signal penetrates the building, and what does is further weakened by roofing and floor materials.
Your WiFi router works differently. WiFi routers use omnidirectional antennas that broadcast in all directions to reach devices throughout your home or office. Because your router’s signal stays mostly indoors and Sail’s signal is pointed outward, they don’t meaningfully overlap, even when they happen to use the same channel.
We also choose channels carefully. Our engineers configure Sail equipment to use channels that help minimize overlap with typical home and office WiFi.
If you’re having WiFi trouble, the cause is almost always something inside the home, such as router placement, walls, or a congested channel. Restarting your router or moving it to a more central location often helps.
