OSBRiDGE 5GXt deployment, Case Scenario 1


The devices were deployed on a 1200 meters distance. One of the devices is deployed on a 40 meters tall tower, the other one is deployed on the rooftop of a building, 2 meters above the roof. There's a clear line of sight between these two points and fresnel zone is partialy obstructed.

Pictures of the instalation on the tower:

Pictures of the installation on the rooftop, on second side of our link:

For testing purposes we have configured devices to operate using 40MHz channel widths.

Iperf was used to test the link throughput, first using TCP/IP:

As you can see the 45 Mbps full duplex real TCP/IP traffic was achieved.

UDP throughput test was performed too:

Results: 61.7/52.00 Mbps full duplex UDP throughput.

Please note that all these tests are performed using uncompressable data, therefore they are pretty close to the real life traffic. This has nothing to do with so-called 'test' traffic which is highly compressable, may give better visual effects, but is hardly ever spotted in real-life deployment scenarios.
