Throughput
 

Tests of TCP throughput were conducted using a single 2x2 MIMO client (two spatial streams) in separate tests of downstream and upstream throughput in both 2.4GHz and 5GHz bands. All three Ruijie APs were compared to both Ubiquiti APs in the 2.4GHz and, additionally, with the Huawei AP in the 5GHz test. See Figures 2 and 3 for all throughput test results.

2.4GHz Radios

In the test of downstream traffic, all of the Ruijie APs outperformed the Ubiquiti APs by anywhere from 10Mbps to 16Mbps. In the test of upstream traffic, the Ruijie RG-AP720-L and RG- AP730-L outperformed Ubiquiti APs by 6 to 8Mbps. The Ruijie RG-AP710 had throughput 1 to 3Mbps lower than Ubiquiti.

5GHz Radios

In the test of downstream traffic, all of the Ruijie APs outperformed the other APs by anywhere from 40Mbps to 170Mbps. In the test of downstream traffic, all of the Ruijie APs outperformed the other APs by anywhere from 23Mbps to 70Mbps.

Long Distance (40 Meters)

Tests of TCP throughput were conducted using a single Apple iPhone 6s client (2x2 MIMO, 2 spatial streams) using a hotel corridor having no obstructions with APs installed on the ceiling. Tests were run between the Ruijie AP-710 and the Ubiquiti "long range" AP, the UAP-AC-LR at both 2.4GHz and 5GHz bands and separately for downstream and upstream traffic. See Figure 4 and Table 2 for all long- range test results.

2.4GHz Radios

In the 2.4GHz tests, the Ruijie and Ubiquiti results were comparable with the Ruijie AP delivering 3Mbps higher throughput in the downstream test and the Ubiquiti AP delivering 3Mbps higher throughput in the upstream test. Engineers noted that the Ruijie signal strength of -44 dBm was betterthan the Ubiquiti signal strength of-56 dBm at 2.4GHz.

5GHz Radios

In the 5GHz tests, the Ruijie results were better in both the downstream and upstream traffic scenarios. In the downstream scenario, Ruijie's throughput was 48Mbps greater than Ubiquiti and in the upstream scenario it was 7Mbps greater than Ubiquiti.

L2&L3 Roaming

Tests of roaming frame loss were conducted for pairs of Ruijie and Ubiquiti APs at both layer 2 and layer 3. In the layer 2 scenario both APs under test were part of the same IP subnet. In the layer 3 test, each AP was part of a different IP subnet.

In both scenarios, the client was able to roam seamlessly using the Ruijie APs with no frame loss and, thus, no session interruption.

For Ubiquiti, engineers measured one frame dropped in the layer 2 scenario and eight frames dropped in the layer 3 scenario. The Ubiquiti re-association in the layer 3 scenario caused more than two seconds of service interruption each time the test was run. See Figure 5 for results.
