WiFi Bridges are used in the following applications:
Long-distance point to point links: Ubiquiti offers several types of bridges that are excellent options:
- The PowerBeam series is the best equipment for low-cost point-to-point links, of up to 6 miles (depending on congestion), if high throughput is not needed: One PowerBeam on each end of the link.
- For very long-distance links (over 7 miles): Use a Ubiquiti RocketM5 with a RocketDish on each side of the link:
- Use the 30dBi RocketDish (2-FT diameter) for less than 20 miles.
- For more than 20 miles, use the RocketDish 34dBi, which is 3-FT in diameter.
Point-to-point bridges: Antenna-type used in a is parabolic-type antenna:
- Parabolics are also known as "dish" or "grid" antennas. Grid or dish antennas are far better than Yagi for point to point.
- Ubiquiti bridges have a parabolic antenna integrated as part of the bridge
Point-to-multipoint bridges: Antenna-type used is typically sectoral or panel antenna, but Yagi antennas can be used.
- For long point-to-point to multipoint links to end-users (such as a marina): RocketM2 with a large 2.4GHz sectoral antenna
- For long point-to-multi-point links to locations such as a building: Use Ubiquiti RocketM5 with a large 5GHz sectoral antenna
- Point-to-multipoint bridge using Ubiquiti NanoSation M5 (5GHz) passing signal through 3 or 4 walls in an apartment building with NanoStation M5 on each end
- WiFi Frequency Ranges: 2.4GHz, 5GHz, 900MHz: (uses, advantages & disadvantages of each frequency band)
- Mounts for Bridges
If you are not an expert, and you are experimenting with trying to make a very long-distance link try this:
- Use signal booster with a high-gain antenna on one end. Test and if it's not enough signal-strength; put a high-gain antenna on both ends.
- If it's not enough signal-strength: Put a high-gain grid antenna (such as the A24 Grid Antenna above-left) on both ends.
- 4Gbps throughput achieved by 4x4 MIMO, Dual Link, Beamforming & "Auto Everything" technologies:
- Range up to 100-km. Throughput over long distances of approximately 1Gbps, even with congestion in 5 GHz band
- We can project throughput for your point-to-point link requirement
