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. System Information screen from the first device (OSBRiDGE 5GXt): and System Information screen from the second device (OSBRiDGE 5GXt): Iperf was used to test the link throughput, first using TCP/IP: # iperf -c 192.168.20.1 -i 5 -t 30 -r ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ ------------------------------------------------------------ Client connecting to 192.168.20.1, TCP port 5001 TCP window size: 16.0 KByte (default) ------------------------------------------------------------ [ 6] local 192.168.20.8 port 32799 connected with 192.168.20.1 port 5001 [ 6] 0.0- 5.0 sec 37.3 MBytes 62.6 Mbits/sec [ 6] 5.0-10.0 sec 37.4 MBytes 62.7 Mbits/sec [ 6] 10.0-15.0 sec 37.4 MBytes 62.7 Mbits/sec [ 6] 15.0-20.0 sec 37.3 MBytes 62.7 Mbits/sec [ 6] 20.0-25.0 sec 37.4 MBytes 62.7 Mbits/sec [ 6] 25.0-30.0 sec 37.4 MBytes 62.7 Mbits/sec [ 6] 0.0-30.0 sec 224 MBytes 62.7 Mbits/sec [ 6] local 192.168.20.8 port 5001 connected with 192.168.20.1 port 32800 [ 6] 0.0- 5.0 sec 36.5 MBytes 61.2 Mbits/sec [ 6] 5.0-10.0 sec 36.3 MBytes 60.9 Mbits/sec [ 6] 10.0-15.0 sec 35.8 MBytes 60.1 Mbits/sec [ 6] 15.0-20.0 sec 36.6 MBytes 61.5 Mbits/sec [ 6] 20.0-25.0 sec 36.6 MBytes 61.5 Mbits/sec [ 6] 25.0-30.0 sec 36.6 MBytes 61.5 Mbits/sec [ 6] 0.0-30.0 sec 219 MBytes 61.1 Mbits/sec firewall: -root- # As you can see the link was capable of running 62.7 Mbps real TCP/IP traffic in one direction and 61.1 Mbps real TCP/IP traffic in the other direction.

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.
